CHAPTER 1 Introducing the ZyWALL This chapter gives an overview of the ZyWALL. It explains the front panel ports, LEDs, introduces the management methods, and lists different ways to start or stop the ZyWALL. 1.1 Overview and Key Default Settings The ZyWALL is an Internet Security Gateway designed for Small and Medium Businesses (SMB). Its flexible configuration helps network administrators set up the network and enforce security policies efficiently.
Chapter 1 Introducing the ZyWALL The following table describes the LEDs. Table 1 Front Panel LEDs LED COLOR STATUS DESCRIPTION Off The ZyWALL is turned off. Green On The ZyWALL is turned on. Red On There is a hardware component failure. Shut down the device, wait for a few minutes and then restart the device (see Section 1.4 on page 55). If the LED turns red again, then please contact your vendor. Green Off The ZyWALL is not ready or has failed. On The ZyWALL is ready and running.
Chapter 1 Introducing the ZyWALL 1.3.2 Command-Line Interface (CLI) The CLI allows you to use text-based commands to configure the ZyWALL. You can access it using remote management (for example, SSH or Telnet) or via the console port. See the Command Reference Guide for more information about the CLI. 1.3.3 Console Port You can use the console port to manage the ZyWALL. You have to use CLI commands, which are explained in the Command Reference Guide.
Chapter 1 Introducing the ZyWALL " It is recommended you use the shutdown command before turning off the ZyWALL. When you apply configuration files or running shell scripts, the ZyWALL does not stop or start the system processes. However, you might lose access to network resources temporarily while the ZyWALL is applying configuration files or running shell scripts.
CHAPTER 2 Features and Applications This chapter introduces the main features and applications of the ZyWALL. 2.1 Features The ZyWALL’s security features include VPN, firewall, anti-virus, content filtering, IDP (Intrusion Detection and Prevention), ADP (Anomaly Detection and Protection), and certificates. It also provides bandwidth management, NAT, port forwarding, policy routing, DHCP server and many other powerful features.
Chapter 2 Features and Applications Intrusion Detection and Prevention (IDP) IDP (Intrusion Detection and Protection) can detect malicious or suspicious packets and respond instantaneously. It detects pattern-based attacks in order to protect against networkbased intrusions. See Section 29.8.2 on page 427 for a list of attacks that the ZyWALL can protect against. You can also create your own custom IDP rules.
Chapter 2 Features and Applications Table 4 Packet Flow Key AC Application Classifier is the Application Protocol (AP) layer-7 classifier. DNAT Destination NAT Routing Routing includes policy routes, interface routing, static routes and load balancing for example.
Chapter 2 Features and Applications Ethernet -> VLAN -> Encap -> ALG -> AC -> DNAT-> Routing -> FW -> AC -> IDP -> AV -> AP -> CF -> SNAT -> IPSec E -> Routing -> BWM -> Encap -> VLAN -> Ethernet 2.3 Applications These are some example applications for your ZyWALL. See also Chapter 6 on page 125 for configuration tutorial examples. 2.3.1 VPN Connectivity Set up VPN tunnels with other companies, branch offices, telecommuters, and business travelers to provide secure access to your network.
Chapter 2 Features and Applications With reverse proxy mode, remote users can easily access any web-based applications on the local network by clicking on links or entering the provided URL. You do not have to install additional client software on the remote user computers for access. Figure 4 Network Access Mode: Reverse Proxy 2.3.2.2 Full Tunnel Mode In full tunnel mode, a virtual connection is created for remote users with private IP addresses in the same subnet as the local network.
Chapter 2 Features and Applications Figure 6 Applications: User-Aware Access Control 2.3.4 Multiple WAN Interfaces Set up multiple connections to the Internet on the same port, or set up multiple connections on different ports. In either case, you can balance the loads between them. Figure 7 Applications: Multiple WAN Interfaces 2.3.5 Device HA Set up an additional ZyWALL as a backup gateway to ensure the default gateway is always available for the network.

CHAPTER 5 Configuration Basics This section provides information to help you configure the ZyWALL effectively. Some of it is helpful when you are just getting started. Some of it is provided for your reference when you configure various features in the ZyWALL. • Section 5.1 on page 111 introduces (very briefly) how granular the configuration is in the ZyWALL. • Section 5.
Chapter 5 Configuration Basics 5.2 Terminology in the ZyWALL This section highlights some differences in terminology or organization between the ZyWALL and other routers, particularly ZyNOS routers.
Chapter 5 Configuration Basics A physical port is the place to which you connect the cable. As shown above, you do not usually configure physical ports to use various features. You configure interfaces and zones. The ZyWALL supports one-to-one, one-to-many, many-to-one, and many-to-none relationships between physical ports and interfaces. There are many types of interfaces in the ZyWALL.
Chapter 5 Configuration Basics Figure 43 Interfaces and Zones: Example • The LAN zone contains the ge1 (Gigabit Ethernet 1) interface. This is a protected zone and uses private IP addresses. ge1 uses 192.168.1.1 and the connected devices use IP addresses in the 192.168.1.2 to 192.168.1.254 range. • The WAN zone contains interfaces ge2 and ge3. They use public IP addresses to connect to the Internet. • The DMZ zone contains interface ge4. The DMZ zone has servers that are available to the public.
Chapter 5 Configuration Basics PREREQUISITES These are other features you should configure before you configure the main screen(s) for this feature. If you did not configure one of the prerequisites first, you can often select an option to create a new object. After you create the object you return to the main screen to finish configuring the feature. You may not have to configure everything in the list of prerequisites.
Chapter 5 Configuration Basics PREREQUISITES Interfaces WHERE USED Policy routes Example: See Chapter 6 on page 125. 5.4.4 IPSec VPN Use IPSec VPN to provide secure communication between two sites over the Internet or any insecure network that uses TCP/IP for communication. The ZyWALL also offers hub-andspoke VPN. MENU ITEM(S) VPN > IPSec VPN; you can also use the VPN Setup Wizard, which handles most of the prerequisites for you.
Chapter 5 Configuration Basics Zones cannot overlap. Each interface and VPN tunnel can be assigned to at most one zone. Virtual interfaces are automatically assigned to the same zone as the interface on which they run. When you create a zone, the ZyWALL does not create any firewall rules, assign an IDP profile, or configure service control for the new zone.
Chapter 5 Configuration Basics 2 Click Network > Routing > Policy Route to go to the policy route configuration screen. Add a policy route. 3 Name the policy route. 4 Select the interface that the traffic comes in through (ge4 in this example). 5 Select the FTP server’s address as the source address. 6 You don’t need to specify the destination address or the schedule. 7 For the service, select FTP.
Chapter 5 Configuration Basics 2 Create an address object for the VoIP server (Object > Address). 3 Click Firewall to go to the firewall configuration. 4 Select from the DMZ-2 zone to the LAN zone, and add a firewall rule using the items you have configured. • You don’t need to specify the schedule or the user. • In the Source field, select the address object of the VoIP server. • You don’t need to specify the destination address. • Leave the Access field set to Allow and the Log field set to No.
Chapter 5 Configuration Basics 5.4.14 Anti-Virus Use anti-virus to detect and take action on viruses. You must subscribe to use anti-virus. You can subscribe using the Licensing > Registration screens or one of the wizards. MENU ITEM(S) Anti-X > AV PREREQUISITES Registration, zones 5.4.15 IDP Use IDP to detect and take action on malicious or suspicious packets. You must subscribe to use IDP. You can subscribe using the Licensing > Registration screens or one of the wizards.
Chapter 5 Configuration Basics 11 Add a policy that uses the schedule, the filtering profile and the user that you created. 5.4.18 Virtual Server (Port Forwarding) Use this to change the address and/or port number of packets coming in from a specified interface. This is also known as port forwarding. The ZyWALL does not check to-ZyWALL firewall rules for packets that are redirected by virtual server. It does check regular (through-ZyWALL) firewall rules.
Chapter 5 Configuration Basics 5.4.20 ALG The ZyWALL’s Application Layer Gateway (ALG) allows VoIP and FTP applications to go through NAT on the ZyWALL. You can also specify additional signaling port numbers. MENU ITEM(S) Network > ALG 5.5 Objects Objects store information and are referenced by other features. If you update this information in response to changes, the ZyWALL automatically propagates the change through the features that use the object. The following table introduces the objects.
Chapter 5 Configuration Basics Table 28 TYPE ABILITIES Guest Access network services Ext-User The same as a User or a Guest. The ZyWALL looks for the specific type in an external authentication server. If the type is not available, the ZyWALL applies default settings. If you want to force users to log in to the ZyWALL before the ZyWALL routes traffic for them, you might have to configure prerequisites first. MENU ITEM(S) Object > User/Group PREREQUISITES Addresses, address groups, schedules.
Chapter 5 Configuration Basics 5.6.2 File Manager Use these screens to upload, download, delete, or run scripts of CLI commands. You can manage • Configuration files. Use configuration files to back up and restore the complete configuration of the ZyWALL. You can store multiple configuration files in the ZyWALL and switch between them without restarting. • Shell scripts. Use shell scripts to run a series of CLI commands.
CHAPTER 6 Tutorials This chapter provides some examples of using the web configurator to set up features in the ZyWALL. See also Chapter 26 on page 351 for an example of configuring L2TP. 6.1 Interfaces and Zones The following example shows how to use port grouping, Ethernet interfaces, trunks, and zones to set up the following configuration.

Create the VPN tunnel between IP addresses 192.168.1.33 to 192.168.1.232 on our local network A and the remote network B (192.168.10.0/24).
Chapter 6 Tutorials Figure 60 VPN > IPSec VPN > VPN Gateway > Add 6.2.3 Set up the VPN Connection The VPN connection manages the IPSec SA. You have to set up the address objects for the local network and remote network before you can set up the VPN connection. 1 Click Object > Address > Address. Click the Add icon. 2 Give the new address object a name (“VPN_LOCAL_RANGE”), change the Address Type to RANGE, and set up the rest of the fields to 192.168.1.33 and 192.168.1.232. Click OK.
Chapter 6 Tutorials Figure 62 VPN > IPSec VPN > VPN Connection > add 6.2.4 Set up the Policy Route for the VPN Tunnel You should create a new policy route to use the VPN tunnel. This policy route will only use the existing address objects, so you do not have to create any additional objects first. 1 Click Network > Routing > Policy Route.
Chapter 6 Tutorials Figure 64 Network > Routing > Policy Route > Add Because the new VPN connection has not been assigned to a zone yet, there are no restrictions (for example, firewall) on traffic to or from this VPN connection. You should set up the VPN settings on the remote IPSec router and try to establish the VPN tunnel before continuing. 6.2.5 Set up the Zone for the VPN Tunnel The new VPN connection has not been assigned to a zone yet.
Chapter 6 Tutorials 6.3 Device HA This example is going to show you how to set up device HA as illustrated below. Figure 66 Device HA Example 192.168.1.1 192.168.1.101 In this example, router A is the default gateway for the network and uses IP address 192.168.1.1. This is the default gateway IP address for the network. There are two ZyWALL routers to ensure this gateway is available. Router A is the master; router B is the backup. Router B has a management IP address of 192.168.1.101.
Chapter 6 Tutorials Figure 67 Device HA > VRRP Group > Add: ge1 3 Click Status, and scroll down to the Interface Status Summary. The H/A Status field is Active. Figure 68 Status: Interface Status Summary: Device HA Master Configured 4 Repeat these steps for the interface that is connected to the Internet. The second VRRP group should have a different VR ID. Part of an example using ge4 is shown below.
Chapter 6 Tutorials Figure 69 Network > Device HA > VRRP Group > Add: ge4 " Once you configure an interface in a VRRP group, you should not configure the interface to have a dynamic IP address. 6.3.3 Set up the Password for Synchronization 1 Click Device HA > Synchronize. 2 Type the password for synchronization in the Password field. This password does not have to be the same as the password for the admin account, but you have to set the same password in the master and backup. Click Apply.
Chapter 6 Tutorials 6.3.4 Finish Configuring the Master Finish configuring the master. The backup router will get these updates later, when it synchronizes with the master. 6.3.5 Set up the Ethernet Interfaces on the Backup On the backup ZyWALL, ge1 should be configured exactly the same way it is configured on the master, including the same IP address. Therefore, you should not configure the backup while it is connected to the same network as the master, or there will be an IP address conflict.
Chapter 6 Tutorials 6.3.7 Synchronize the Backup 1 Connect the backup to the same network as the master. 2 Click Device HA > Synchronize. 3 Type the password for synchronization in the Password field. Enter the IP address of the master (on a secure network), and click Sync Now to get the configuration from the master. Figure 73 Device HA > Synchronize You can also set up the backup to synchronize with the master at regular intervals. 6.
Chapter 6 Tutorials 6.4.1 Set up User Accounts Set up one user account for each user account in the RADIUS server. If it is possible to export user names from the RADIUS server to a text file, then you might create a script to create the user accounts instead. This example uses the web configurator. 1 Click User/Group > User. Click the Add icon. 2 Enter the same user name that is used in the RADIUS server, and set the User Type to Ext-User because this user account is authenticated by an external server.
Chapter 6 Tutorials 6.4.3 Set up User Authentication Using the RADIUS Server This step sets up user authentication using the RADIUS server. First, configure the settings for the RADIUS server. Then, set up the authentication method, and configure the ZyWALL to use the authentication method. Finally, force users to log in to the ZyWALL before it routes traffic for them. 1 Click Object > AAA Server > RADIUS > Default. Configure the RADIUS server, and click Apply.
Chapter 6 Tutorials " The users will have to log in using the web configurator login screen before they can use HTTP or MSN.

After the screen refreshes, enter 2 and 1 in the Weight column for ge2 and ge3, respectively. Click OK.
Chapter 6 Tutorials The firewall is enabled, so you also need to create a rule to allow traffic in from the WAN zone. Figure 89 NAT 1:1 Example Network Topology 192.168.1.21 1.1.1.1 6.6.1 NAT 1:1 Address Objects First create two address objects for the private and public IP addresses (LAN_SMTP and WAN_EG) in the Object > Address screen as shown next.
Chapter 6 Tutorials 6.6.2 NAT 1:1 Virtual Server This section sets up a virtual server rule that changes the destination of SMTP traffic coming to IP address 1.1.1.1 at the ZyWALL’s ge3 (WAN) interface, to the LAN SMTP server’s IP address (192.168.1.21). This is also called Destination NAT (DNAT) Figure 92 NAT 1:1 Example Virtual Server Destination 192.168.1.21 SMTP NAT Destination 1.1.1.1 SMTP 192.168.1.21 The ge3 WAN interface has a different IP address than 1.1.1.

Be careful of where you create the route as routes are ordered in descending priority. Figure 95 Create a Policy Route 6.6.4 NAT 1:1 Firewall Rule Create a firewall rule to allow access from the WAN zone to the mail server in the LAN zone.
Chapter 6 Tutorials Figure 96 Create a Firewall Rule 6.7 NAT Loopback The NAT 1:1 example in Section 6.6 on page 147 maps a public IP address to the private IP address of a LAN SMTP mail server to allow users to access the SMTP mail server from the WAN. LAN users can also use an IP address to access the mail server. However, you need to configure NAT loopback for LAN users to use a domain name to access the server. Figure 97 LAN Computer Queries the DNS Server DNS xxx.LAN-SMTP.com = 1.1.1.1 xxx.LAN-SMTP.
Chapter 6 Tutorials 6.7.1 NAT Loopback Virtual Server When a LAN user sends SMTP traffic to IP address 1.1.1.1, the traffic comes into the ZyWALL through the ge1 (LAN) interface, thus it does not match the NAT 1:1 mapping’s virtual server rule for SMTP traffic coming to IP 1.1.1.1 from ge3 (the WAN). So you must configure a similar virtual server rule for ge1. Figure 98 NAT Loopback Virtual Server NAT Destination 192.168.1.21 1.1.1.1 Destination 1.1.1.1 SMTP SMTP LAN 192.168.1.21 192.168.1.
Chapter 6 Tutorials 6.7.2 NAT Loopback Policy Route Without a NAT loopback policy route, the LAN user SMTP traffic goes to the LAN SMTP server has the LAN computer’s IP address as the source. The source address is in the same subnet, so the LAN SMTP server replies directly. The return traffic uses the SMTP server’s LAN IP address as the source address1. This creates a triangle route since the source does not match the original destination address (1.1.1.1). The user’s computer shuts down the session.
Chapter 6 Tutorials Figure 102 Create a Policy Route Now the LAN SMTP server replies to the ZyWALL’s LAN IP address and the ZyWALL changes the source address to 1.1.1.1 before sending it to the LAN user’s computer. The source in the return traffic matches the original destination address (1.1.1.1) and the LAN user can use the LAN SMTP server. Figure 103 NAT Loopback Successful NAT Source 192.168.1.21 Source 1.1.1.1 SMTP SMTP LAN 192.168.1.21 154 192.168.1.
Chapter 6 Tutorials 6.8 Service Control and the Firewall Service control lets you configure rules that control HTTP and HTTPS management access (to the web configurator) and separate rules that control HTTP and HTTPS user access (logging into SSL VPN for example). See Chapter 44 on page 587 for more on service control. The To-ZyWALL firewall rules apply to any kind of HTTP or HTTPS connection to the ZyWALL. They do not distinguish between administrator management access and user access.
Chapter 6 Tutorials Figure 105 System > WWW > Service Control Rule Edit 4 Click Apply. Figure 106 System > WWW Now administrators can only log into the web configurator from the LAN zone. Non-admin users can still use HTTPS to log into the ZyWALL from any of the ZyWALL’s zones (to use SSL VPN for example).
CHAPTER 7 Status This chapter explains the Status screen, which is the screen you see when you first log in to the ZyWALL or when you click Status. 7.1 Status Screen Use this screen to look at the ZyWALL’s general device information, system status, system resource usage, licensed service status, and interface status.

CHAPTER 10 Interface See Section 5.4.2 on page 115 for related information on these screens. 10.1 Interface Overview In general, an interface has the following characteristics. • • • • • • An interface is a logical entity through which (layer-3) packets pass. An interface is bound to a physical port or another interface. Many interfaces can share the same physical port. An interface is bound to at most one zone. Many interface can belong to the same zone.
Chapter 10 Interface • Trunks manage load balancing between interfaces. Port groups, trunks, and the auxiliary interface have a lot of characteristics that are specific to each type of interface. They are discussed in more detail in Section 10.3.1 on page 194, Chapter 11 on page 219, and Section 10.7.1 on page 215, respectively. The other types of interfaces--Ethernet, VLAN, bridge, PPPoE/PPTP, and virtual--have a lot of similar characteristics.
Chapter 10 Interface Figure 122 Example: Entry in the Routing Table Derived from Interfaces Table 44 Example: Routing Table Entries for Interfaces IP ADDRESS(ES) DESTINATION 100.100.1.1/16 ge1 200.200.200.1/24 ge2 For example, if the ZyWALL gets a packet with a destination address of 100.100.25.25, it routes the packet to interface ge1. If the ZyWALL gets a packet with a destination address of 200.200.200.200, it routes the packet to interface ge2.
Chapter 10 Interface 10.1.3 Interface Parameters The ZyWALL restricts the amount of traffic into and out of the ZyWALL through each interface. • Upstream bandwidth is the amount of traffic from the ZyWALL through the interface to the network. • Downstream bandwidth is the amount of traffic from the network through the interface into the ZyWALL.2 If you set the bandwidth restrictions very high, you effectively remove the restrictions. The ZyWALL also restricts the size of each data packet.
Chapter 10 Interface Table 46 Example: Assigning IP Addresses from a Pool (continued) START IP ADDRESS POOL SIZE RANGE OF ASSIGNED IP ADDRESS 99.99.1.1 1023 99.99.1.1 - 99.99.4.255 120.120.120.100 100 120.120.120.100 - 120.120.120.199 The ZyWALL cannot assign the first address (network address) or the last address (broadcast address) in the subnet defined by the interface’s IP address and subnet mask. For example, in the first entry, if the subnet mask is 255.255.255.
Chapter 10 Interface 10.1.6 Relationships Between Interfaces In the ZyWALL, interfaces are usually created on top of other interfaces. Only Ethernet interfaces are created directly on top of the physical ports (or port groups). The relationships between interfaces are explained in the following table.
Chapter 10 Interface In addition, you use Ethernet interfaces to control which physical ports exchange routing information with other routers and how much information is exchanged through each one. The more routing information is exchanged, the more efficient the routers should be. However, the routers also generate more network traffic, and some routing protocols require a significant amount of configuration and management. The ZyWALL supports two routing protocols, RIP and OSPF.

Chapter 10 Interface Each physical port is assigned to one Ethernet interface. In port grouping, the Ethernet interfaces are called representative interfaces. If you assign more than one physical port to a representative interface, you create a port group. Port groups have the following characteristics: • There is a layer-2 Ethernet switch between physical ports in the port group. This provides wire-speed throughput but no security.
Chapter 10 Interface Figure 129 Network > Interface > Port Grouping Each section in this screen is described below. Table 51 Network > Interface > Port Grouping LABEL DESCRIPTION Representative Interface (ge1, ge2, ge3, ge4, ge5, ge6, ge7) These are Ethernet interfaces. To add a physical port to a representative interface, drag the physical port onto the corresponding representative interface.
Chapter 10 Interface Figure 130 Example: Before VLAN A B C In this example, there are two physical networks and three departments A, B, and C. The physical networks are connected to hubs, and the hubs are connected to the router. Alternatively, you can divide the physical networks into three VLANs. Figure 131 Example: After VLAN A B Each VLAN is a separate network with separate IP addresses, subnet masks, and gateways. Each VLAN also has a unique identification number (ID).
Chapter 10 Interface • Better manageability - You can align network policies more appropriately for users. For example, you can create different content filtering rules for each VLAN (each department in the example above), and you can set different bandwidth limits for each VLAN. These rules are also independent of the physical network, so you can change the physical network without changing policies. In this example, the new switch handles the following types of traffic: • • • • Inside VLAN 2.

Chapter 10 Interface 10.5.1 Bridge Overview A bridge creates a connection between two or more network segments at the layer-2 (MAC address) level. In the following example, bridge X connects four network segments. When the bridge receives a packet, the bridge records the source MAC address and the port on which it was received in a table. It also looks up the destination MAC address in the table. If the bridge knows on which port the destination MAC address is located, it sends the packet to that port.
Chapter 10 Interface 10.5.2 Bridge Interface Overview A bridge interface creates a software bridge between the members of the bridge interface. It also becomes the ZyWALL’s interface for the resulting network.

Chapter 10 Interface PPPoE is often used with cable modems and DSL connections. It provides the following advantages: • The access and authentication method works with existing systems, including RADIUS. • You can access one of several network services. This makes it easier for the service provider to offer the service • PPPoE does not usually require any special configuration of the modem. PPTP is used to set up virtual private networks (VPN) in unsecure TCP/IP environments. It sets up two sessions.

CHAPTER 11 Trunks This chapter shows you how to configure trunks on your ZyWALL. See Section 5.4.3 on page 115 for related information on these screens. 11.1 Trunks Overview You can group multiple interfaces together into trunks to have multiple connections share the traffic load to increase overall network throughput and enhance network reliability. If one interface’s connection goes down, the ZyWALL sends traffic through another member of the trunk.
Chapter 11 Trunks Maybe you have two connections with different bandwidths. For jitter-sensitive traffic (like video for example), you could set up a trunk group that uses spillover or weighted round robin load balancing to make sure that most of the jitter-sensitive traffic goes through the higherbandwidth interface. For some traffic connections, you might want to use least load first load balancing in order to even out the distribution of the traffic load. 11.
Chapter 11 Trunks 11.4.2 Weighted Round Robin Round Robin scheduling services queues on a rotating basis and is activated only when an interface has more traffic than it can handle. A queue is given an amount of bandwidth irrespective of the incoming traffic on that interface. This queue then moves to the back of the list. The next queue is given an equal amount of bandwidth, and then moves to the end of the list; and so on, depending on the number of queues being used.

When this spillover bandwidth limit is exceeded, the ZyWALL sends new session traffic through the next interface.
CHAPTER 12 Policy and Static Routes This chapter shows you how to configure policies for IP routing and static routes on your ZyWALL. See Section 5.4.10 on page 117 for related information on the policy route screens. 12.1 Policy Route Traditionally, routing is based on the destination address only and the ZyWALL takes the shortest path to forward a packet.
Chapter 12 Policy and Static Routes IPPR follows the existing packet filtering facility of RAS in style and in implementation. 12.2.1 NAT and SNAT NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address in a packet in one network to a different IP address in another network. Use SNAT (Source NAT) to change the source IP address in one network to a different IP address in another network. 12.2.
Chapter 12 Policy and Static Routes Figure 148 Trigger Port Forwarding Example 12.2.3 Maximize Bandwidth Usage The maximize bandwidth usage option allows the ZyWALL to divide up any available bandwidth on the interface (including unallocated bandwidth and any allocated bandwidth that a policy route is not using) among the policy routes that require more bandwidth. When you enable maximize bandwidth usage, the ZyWALL first makes sure that each policy route gets up to its bandwidth allotment.

Table 69 Network > Routing > Static Route > Edit 234 LABEL DESCRIPTION Destination IP This parameter specifies the IP network address of the final destination. Routing is always based on network number. If you need to specify a route to a single host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the network number to be identical to the host ID.
CHAPTER 13 Routing Protocols This chapter describes how to set up RIP and OSPF routing protocol settings for the ZyWALL. First, it provides an overview of RIP and OSPF, and, then, it introduces the RIP and OSPF screens used to configure routing protocols. See Section 5.5 on page 122 for related information on these screens. 13.1 Routing Protocols Overview Routing protocols give the ZyWALL routing information about the network from other routers.
Chapter 13 Routing Protocols RIP uses UDP port 520. 13.1.2 Authentication Types Authentication is used to guarantee the integrity, but not the confidentiality, of routing updates. The transmitting router uses its key to encrypt the original message into a smaller message, and the smaller message is transmitted with the original message. The receiving router uses its key to encrypt the received message and then verifies that it matches the smaller message sent with it.
Chapter 13 Routing Protocols Figure 154 Network > Routing > RIP The following table describes the labels in this screen. Table 71 Network > Routing Protocol > RIP LABEL DESCRIPTION Authentication Authentication Select the authentication method used in the RIP network. Choices are: None, Text, and MD5. Text Authentication Key This field is available if the Authentication is Text. Type the password for text authentication.
Chapter 13 Routing Protocols • OSPF filters and summarizes routing information, which reduces the size of routing tables throughout the network. • OSPF responds to changes in the network, such as the loss of a router, more quickly. • OSPF considers several factors, including bandwidth, hop count, throughput, round trip time, and reliability, when it calculates the shortest path. • OSPF converges more quickly than RIP.
Chapter 13 Routing Protocols This OSPF AS consists of four areas, areas 0-3. Area 0 is always the backbone. In this example, areas 1, 2, and 3 are all connected to it. Area 1 is a normal area. It has routing information about the OSPF AS and networks X and Y. Area 2 is a stub area. It has routing information about the OSPF AS, but it depends on a default route to send information to networks X and Y. Area 3 is a NSSA. It has routing information about the OSPF AS and network Y but not about network X. 13.
Chapter 13 Routing Protocols Figure 156 OSPF: Types of Routers In order to reduce the amount of traffic between routers, a group of routers that are directly connected to each other selects a designated router (DR) and a backup designated router (BDR). All of the routers only exchange information with the DR and the BDR, instead of exchanging information with all of the other routers in the group.
Chapter 13 Routing Protocols 2 Set up the OSPF areas. 3 Configure the appropriate interfaces. See Section 10.2.1 on page 184. 4 Set up virtual links, as needed. 13.4 OSPF Screens The OSPF screens are used to specify the ID the ZyWALL uses in the OSPF AS and to maintain the policies for redistribution. In addition, they are also used to create, maintain, and remove OSPF areas. 13.4.1 OSPF Summary The OSPF screen is used to specify the OSPF router and maintain the policies for redistribution.

CHAPTER 14 Zones Set up zones to configure network security and network policies in the ZyWALL.See Section 5.4.7 on page 116 for related information on these screens. 14.1 Zones Overview A zone is a group of interfaces and VPN tunnels. The ZyWALL uses zones, not interfaces, in many security and policy settings, such as firewall rules and service control. Zones cannot overlap.
Chapter 14 Zones Intra-zone traffic is traffic between interfaces or VPN tunnels in the same zone. For example, in Figure 160 on page 245, traffic between VLAN 2 and the Ethernet is intra-zone traffic. In each zone, you can either allow or prohibit all intra-zone traffic. For example, in Figure 160 on page 245, you might allow intra-zone traffic in the LAN2 zone but prohibit it in the WAN zone.
Chapter 14 Zones 14.3 Zone Add/Edit The Zone Add/Edit screen allows you to define a zone or edit an existing one.

CHAPTER 15 DDNS This chapter describes how to configure dynamic DNS (DDNS) services for the ZyWALL. First, it provides an overview, and then it introduces the screens. See Section 5.4.9 on page 117 for related information on these screens. 15.1 DDNS Overview DNS maps a domain name to a corresponding IP address and vice versa. Similarly, dynamic DNS maps a domain name to a dynamic IP address. As a result, anyone can use the domain name to contact you (in NetMeeting, CU-SeeMe, etc.
Chapter 15 DDNS 15.1.2 High Availability (HA) The DDNS server maps a domain name to the IP address of one of the ZyWALL’s WAN ports. If that WAN port loses its connection, high availability allows the ZyWALL to substitute the HA port’s IP address in the domain name mapping. 15.1.3 Mail Exchanger DynDNS can route e-mail for your domain name to a specified mail server. The server is called a mail exchanger. For example, if there is e-mail for john-doe@yourhost.dyndns.
Chapter 15 DDNS 15.3 DDNS Summary The DDNS screen provides a summary of all DDNS domain names and their configuration. In addition, this screen allows you to add new domain names, edit the configuration for existing domain names, and delete domain names. To access this screen, login to the web configurator.

CHAPTER 16 Virtual Servers This chapter describes how to set up, manage, and remove virtual servers. First, it provides an overview of virtual servers, and, then, it introduces the virtual server screens and commands. See Section 5.4.18 on page 121 for related information on these screens. 16.1 Virtual Server Overview Virtual server is also known as port forwarding or port translation. " The virtual server changes the destination address of packets. This is also known as Destination NAT (DNAT).
Chapter 16 Virtual Servers The ZyWALL checks virtual servers before it applies to-ZyWALL firewall rules, so toZyWALL firewall rules do not apply to traffic that is forwarded by virtual servers. The ZyWALL still checks regular (through-ZyWALL) firewall rules according to the source IP address and mapped IP address. Some common port numbers are listed in Appendix C on page 701. 16.

CHAPTER 17 HTTP Redirect This chapter shows you how to configure HTTP redirection on your ZyWALL.See Section 5.4.19 on page 121 for related information on these screens. 17.1 HTTP Redirect Overview HTTP redirect forwards the client’s HTTP request (except HTTP traffic destined for the ZyWALL) to a web proxy server. 17.1.1 Web Proxy Server A proxy server helps client devices make indirect requests to access the Internet or outside network resources/services.
Chapter 17 HTTP Redirect Figure 168 HTTP Redirect Example In the example, proxy server A is connected to ge4 in the DMZ zone. When a client connected to ge1 wants to open a web page, its HTTP request is redirected to proxy server A first. If proxy server A cannot find the web page in its cache, a policy route allows it to access the Internet to get them from a server. Proxy server A then forwards the response to the client. To make this example work, make sure you have the following settings.

CHAPTER 18 ALG This chapter covers how to use the ZyWALL’s ALG feature to allow certain applications to pass through the ZyWALL. See Section 5.4.20 on page 122 for related information on these screens. 18.1 ALG Introduction The ZyWALL can function as an Application Layer Gateway (ALG) to allow certain NAT unfriendly applications (such as SIP) to operate properly through the ZyWALL’s NAT.
Chapter 18 ALG You could also have a trunk with one interface set to active and a second interface set to passive. The ZyWALL does not automatically change ALG-managed connections to the second (passive) interface when the active interface’s connection goes down. When the active interface’s connection fails, the client needs to re-initialize the connection through the second interface (that was set to passive) in order to have the connection go through the second interface.
Chapter 18 ALG Figure 171 H.323 ALG Example 18.1.6 SIP The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet. SIP is used in VoIP (Voice over IP), the sending of voice signals over the Internet Protocol. SIP signaling is separate from the media for which it handles sessions.
Chapter 18 ALG 18.1.6.2 SIP Signaling Session Timeout Most SIP clients have an “expire” mechanism indicating the lifetime of signaling sessions. The SIP user agent sends registration packets to the SIP server periodically and keeps the session alive in the ZyWALL. If the SIP client does not have this mechanism and makes no calls during the ZyWALL SIP timeout, the ZyWALL SIP ALG deletes the signaling session after the timeout period. 18.
Chapter 18 ALG For example, you configure firewall and virtual server rules to allow LAN IP address A to receive calls through public WAN IP address 1. You configure different firewall and port forwarding rules to allow LAN IP address B to receive calls through public WAN IP address 2. You configure corresponding policy routes to have calls from LAN IP address A go out through WAN IP address 1 and calls from LAN IP address B go out through WAN IP address 2.
Chapter 18 ALG The following table describes the labels in this screen. Table 83 Network > ALG 270 LABEL DESCRIPTION Enable SIP Transformations SIP is a signaling protocol used in VoIP (Voice over IP), the sending of voice signals over Internet Protocol. Turn on the SIP ALG to allow SIP sessions to pass through the ZyWALL. Using the SIP ALG allows you to use bandwidth management on SIP traffic. SIP Signaling Port If you are using a custom UDP port number (not 5060) for SIP traffic, enter it here.
Chapter 18 ALG 18.4 WAN to LAN SIP Peer-to-peer Calls Example This example shows how to configure firewall and virtual server (port forwarding) rules to allow H.323 calls to come in through WAN IP address 10.0.0.8 to computer A at IP address 192.168.1.56 on the LAN. Figure 176 WAN to LAN H.323 Peer-to-peer Calls Example Configure the virtual server policy first to forward H.323 (TCP port 1720) traffic received on the ZyWALL’s 10.0.0.8 WAN IP address to LAN IP address 192.168.1.56.

CHAPTER 19 Firewall This chapter introduces the ZyWALL’s firewall and shows you how to configure your ZyWALL’s firewall.See Section 5.4.12 on page 118 for related information on these screens. 19.1 Firewall Overview The ZyWALL’s firewall is a stateful inspection firewall. The ZyWALL restricts access by screening data packets against defined access rules. It can also inspect sessions. For example, traffic from one zone is not allowed unless it is initiated by a computer in another zone first.
Chapter 19 Firewall Your customized rules take precedence and override the ZyWALL’s default settings. The ZyWALL checks the schedule, user name (user’s login name on the ZyWALL), source IP address, destination IP address and IP protocol type of network traffic against the firewall rules (in the order you list them). When the traffic matches a rule, the ZyWALL takes the action specified in the rule.
Chapter 19 Firewall The following table explains the default firewall rules for traffic going through the ZyWALL. See Section 19.2.1.2 on page 280 for details on the firewall rules for traffic going to the ZyWALL itself. Table 84 Default Firewall Rules " " FROM ZONE TO ZONE STATEFUL PACKET INSPECTION From LAN to LAN Traffic between interfaces in the LAN is allowed. From LAN to WAN Traffic from the LAN to the WAN is allowed. From LAN to DMZ Traffic from the LAN to the DMZ is allowed.
Chapter 19 Firewall 19.2.1.2 To-ZyWALL Rules Rules with ZyWALL as the To Zone apply to traffic going to the ZyWALL itself. By default, the firewall allows any computer from the LAN zone to access or manage the ZyWALL. By default, the ZyWALL drops most packets from the WAN or DMZ zone to the ZyWALL itself, except for VRRP traffic for Device HA and ESP/AH/IKE/NATT/HTTPS services for VPN tunnels, and generates a log.
Chapter 19 Firewall Figure 183 Blocking All LAN to WAN IRC Traffic Example Your firewall would have the following configuration. Table 85 Blocking All LAN to WAN IRC Traffic Example # USER SOURCE DESTINATION SCHEDULE SERVICE ACTION 1 Any Any Any Any IRC Deny Default Any Any Any Any Any Allow • The first row blocks LAN access to the IRC service on the WAN. • The second row is the firewall’s default policy that allows all traffic from the LAN to go to the WAN.
Chapter 19 Firewall Figure 184 Limited LAN to WAN IRC Traffic Example Your firewall would have the following configuration. Table 86 Limited LAN to WAN IRC Traffic Example 1 # USER SOURCE DESTINATION SCHEDULE SERVICE ACTION 1 Any 192.168.1.7 Any Any IRC Allow 2 Any Any Any Any IRC Deny Default Any Any Any Any Any Allow • The first row allows the LAN computer at IP address 192.168.1.7 to access the IRC service on the WAN.
Chapter 19 Firewall 19.4 Alerts You can choose to generate an alert or log when a rule is matched and have the ZyWALL send an immediate e-mail message to you. Otherwise, see the logs created (for the categories you specified) in the View Log screen. Refer to the chapter on logs for details. 19.5 Asymmetrical Routes If an alternate gateway on the LAN has an IP address in the same subnet as the ZyWALL’s LAN IP address, return traffic may not go through the ZyWALL.
Chapter 19 Firewall 19.6 Configuring the Firewall Click Firewall to open the Firewall screen. This screen varies depending on the firewall rule type and the way you choose to display the firewall rules. " The ordering of your rules is very important as rules are applied in sequence. Specify from which zone packets come and to which zone packets travel to display only the rules specific to the selected direction. Figure 186 Firewall The following table describes the labels in this screen.

CHAPTER 20 IPSec VPN This chapter explains how to set up and maintain IPSec VPNs in the ZyWALL. See Section 5.4.4 on page 116 for related information on these screens. 20.1 IPSec VPN Overview A virtual private network (VPN) provides secure communications between sites without the expense of leased site-to-site lines. A secure VPN is a combination of tunneling, encryption, authentication, access control and auditing.
Chapter 20 IPSec VPN Figure 195 VPN: IKE SA and IPSec SA In this example, a computer in network A is exchanging data with a computer in network B. Inside networks A and B, the data is transmitted the same way data is normally transmitted in the networks. Between routers X and Y, the data is protected by tunneling, encryption, authentication, and other security features of the IPSec SA. The IPSec SA is secure because routers X and Y established the IKE SA first.
Chapter 20 IPSec VPN Usually, you should select ESP. AH does not support encryption, and ESP is more suitable with NAT. 20.1.1.3 Encapsulation There are two ways to encapsulate packets. Usually, you should use tunnel mode because it is more secure. Transport mode is only used when the IPSec SA is used for communication between the ZyWALL and remote IPSec router (for example, for remote management), not between computers on the local and remote networks.
Chapter 20 IPSec VPN If you enable PFS, the ZyWALL and remote IPSec router perform a DH key exchange every time an IPSec SA is established, changing the root key from which encryption keys are generated. As a result, if one encryption key is compromised, other encryption keys remain secure. If you do not enable PFS, the ZyWALL and remote IPSec router use the same root key that was generated when the IKE SA was established to generate encryption keys.
Chapter 20 IPSec VPN • Source address in outbound packets - this translation is necessary if you want the ZyWALL to route packets from computers outside the local network through the IPSec SA. • Source address in inbound packets - this translation hides the source address of computers in the remote network.
Chapter 20 IPSec VPN • Destination - the original destination address; the local network (A). • SNAT - the translated source address; a different IP address (range of addresses) to hide the original source address. 20.1.2.2.3 Destination Address in Inbound Packets (Inbound Traffic, Destination NAT) You can set up this translation if you want the ZyWALL to forward some packets from the remote network to a specific computer in the local network.
Chapter 20 IPSec VPN • Make sure the to-ZyWALL firewall rules allow IPSec VPN traffic to the ZyWALL. IKE uses UDP port 500, AH uses IP protocol 51, and ESP uses IP protocol 50. • The ZyWALL supports UDP port 500 and UDP port 4500 for NAT traversal. If you enable this, make sure the to-ZyWALL firewall rules allow UDP port 4500 too. • Make sure regular firewall rules allow traffic between the VPN tunnel and the rest of the network.
Chapter 20 IPSec VPN Each field is discussed in the following table. See Section 20.3.3 on page 302 and Section 20.3.2 on page 298 for more information.

This is the address object for the remote network. The size of the original source address range (Source) must be equal to the size of the translated source address range (SNAT).
Chapter 20 IPSec VPN It takes several steps to establish an IKE SA. The negotiation mode determines how many. There are two negotiation modes--main mode and aggressive mode. Main mode provides better security, while aggressive mode is faster. " Both routers must use the same negotiation mode. These modes are discussed in more detail in Section 20.4.2.1 on page 310. Main mode is used in various examples in the rest of this section. 20.4.1.
Chapter 20 IPSec VPN " Both routers must use the same encryption algorithm, authentication algorithm, and DH key group. In most ZyWALLs, you can select one of the following encryption algorithms for each proposal. The algorithms are listed in order from weakest to strongest. • Data Encryption Standard (DES) is a widely used method of data encryption. It applies a 56-bit key to each 64-bit block of data. • Triple DES (3DES) is a variant of DES.
Chapter 20 IPSec VPN In main mode, the ZyWALL and remote IPSec router authenticate each other in steps 5 and 6, as illustrated below. The identities are also encrypted using the encryption algorithm and encryption key the ZyWALL and remote IPSec router selected in previous steps.
Chapter 20 IPSec VPN For example, in Table 93 on page 310, the ZyWALL and the remote IPSec router authenticate each other successfully. In contrast, in Table 94 on page 310, the ZyWALL and the remote IPSec router cannot authenticate each other and, therefore, cannot establish an IKE SA. Table 93 VPN Example: Matching ID Type and Content ZYWALL REMOTE IPSEC ROUTER Local ID type: E-mail Local ID type: IP Local ID content: tom@yourcompany.com Local ID content: 1.1.1.
Chapter 20 IPSec VPN 20.4.2.2 VPN, NAT, and NAT Traversal In the following example, there is another router (A) between router X and router Y. Figure 204 VPN/NAT Example If router A does NAT, it might change the IP addresses, port numbers, or both. If router X and router Y try to establish a VPN tunnel, the authentication fails because it depends on this information. The routers cannot establish a VPN tunnel. Most routers like router A now have an IPSec pass-thru feature.
Chapter 20 IPSec VPN • Instead of using the pre-shared key, the ZyWALL and remote IPSec router check the signatures on each other’s certificates. Unlike pre-shared keys, the signatures do not have to match. • The local and peer ID type and content come from the certificates. " You must set up the certificates for the ZyWALL and remote IPSec router first. 20.4.

CHAPTER 27 Application Patrol This chapter describes how to use application patrol for the ZyWALL. It provides an overview first and then introduces the screens. See Section 5.4.13 on page 119 for related information on these screens. 27.1 Application Patrol Overview Application patrol provides a convenient way to manage the use of various applications on the network.
Chapter 27 Application Patrol " The ZyWALL allows the first eight packets to go through the firewall, regardless of the application patrol policy for the application. The ZyWALL examines these first eight packets to identify the application. The second approach is called service ports. In this approach, the ZyWALL only uses OSI level-3 information, such as IP address and port, to identify what application is using the connection.
Chapter 27 Application Patrol 27.4.1 Connection and Packet Directions Application patrol looks at the connection direction, that is from which zone the connection was initiated and to which zone the connection is going. A connection has outbound and inbound packet flows. The ZyWALL controls the bandwidth of traffic of each flow as it is going out through an interface or VPN tunnel. • The outbound traffic flows from the connection initiator to the connection responder.
Chapter 27 Application Patrol Figure 297 LAN to WAN, Outbound 200 kbps, Inbound 500 kbps WAN DMZ LAN GE1 GE2 GE3 GE4 GE5 Outbound: 200 kbps Inbound: 500 kbps Outbound: 200 kbps 27.4.3 Bandwidth Management Priority The ZyWALL gives bandwidth to higher-priority traffic first, until it reaches its configured bandwidth rate. Then lower-priority traffic gets bandwidth. The ZyWALL uses a fairness-based (round-robin) scheduler to divide bandwidth among traffic flows with the same priority.
Chapter 27 Application Patrol Figure 298 Bandwidth Management Behavior BWM 1000 kbps 1000 kbps 1000 kbps 27.4.5.1 Configured Rate Effect In the following table the configured rates total less than the available bandwidth and maximize bandwidth usage is disabled, both servers get their configured rate. Table 108 Configured Rate Effect POLICY CONFIGURED RATE MAX. B. U. PRIORITY ACTUAL RATE A 300 kbps No 1 300 kbps B 200 kbps No 1 200 kbps 27.4.5.
Chapter 27 Application Patrol 27.4.5.4 Priority and Over Allotment of Bandwidth Effect Server A has a configured rate that equals the total amount of available bandwidth and a higher priority. You should regard extreme over allotment of traffic with different priorities (as shown here) as a configuration error. Even though the ZyWALL still attempts to let all traffic get through and not be lost, regardless of its priority, server B gets almost no bandwidth with this configuration.
Chapter 27 Application Patrol Figure 299 Application Patrol Bandwidth Management Example SIP: Any to WAN Outbound: 200 Kbps Inbound: 200 Kbps Priority: 1 Max. B. U. SIP: WAN to Any Outbound: 200 Kbps Inbound: 200 Kbps Priority: 1 Max. B. U. HTTP: Any to WAN Outbound: 100 Kbps Inbound: 500 Kbps Priority: 2 Max. B. U.

Chapter 27 Application Patrol Figure 300 SIP Any to WAN Bandwidth Management Example Outbound: 200 kbps BWM BWM Inbound: 200 kbps 27.5.3 SIP WAN to Any Bandwidth Management Example You also create a policy for calls coming in from the SIP server on the WAN. It is the same as the SIP Any to WAN policy, but with the directions reversed (WAN to Any instead of Any to WAN). 27.5.
Chapter 27 Application Patrol • Third highest priority (3). • Disable maximize bandwidth usage since you do not want to give FTP more bandwidth. Figure 302 FTP WAN to DMZ Bandwidth Management Example Outbound: 300 kbps BWM BWM Inbound: 100 kbps 27.5.6 FTP LAN to DMZ Bandwidth Management Example • The LAN and DMZ zone interfaces are connected to Ethernet networks (not an ADSL device) so you limit both outbound and inbound traffic to 50 Mbps. • Fourth highest priority (4).
Chapter 27 Application Patrol 27.6 Other Applications Sometimes, the ZyWALL cannot identify the application. For example, the application might be a new application, or the packets might arrive out of sequence. (The ZyWALL does not reorder packets when identifying the application.) In these cases, you can still provide a default rule for the ZyWALL to follow.

CHAPTER 28 Anti-Virus This chapter introduces and shows you how to configure the anti-virus scanner.See Section 5.4.14 on page 120 for related information on these screens. 28.1 Anti-Virus Overview A computer virus is a small program designed to corrupt and/or alter the operation of other legitimate programs. A worm is a self-replicating virus that resides in active memory and duplicates itself.
Chapter 28 Anti-Virus 4 Once the virus is spread through the network, the number of infected networked computers can grow exponentially. 28.1.3 Types of Anti-Virus Scanner The section describes two types of anti-virus scanner: host-based and network-based. A host-based anti-virus (HAV) scanner is often software installed on computers and/or servers in the network. It inspects files for virus patterns as they are moved in and out of the hard drive.
Chapter 28 Anti-Virus Figure 313 ZyWALL Anti-virus Example The following describes the virus scanning process on the ZyWALL. 1 The ZyWALL first identifies SMTP, POP3, IMAP4, HTTP and FTP packets through standard ports. 2 If the packets are not session connection setup packets (such as SYN, ACK and FIN), the ZyWALL records the sequence of the packets. 3 The scanning engine checks the contents of the packets for virus.
Chapter 28 Anti-Virus • Encrypted traffic. This could be password-protected files or VPN traffic where the ZyWALL is not the endpoint (pass-through VPN traffic). • Traffic through custom (non-standard) ports. The only exception is FTP traffic. The ZyWALL scans whatever port number is specified for FTP in the ALG screen. • ZIP file(s) within a ZIP file. 28.3 Anti-Virus Summary Click Anti-X > Anti-Virus to display the configuration screen as shown next.

Chapter 30 ADP 30.8.1 Port Scanning An attacker scans device(s) to determine what types of network protocols or services a device supports. One of the most common port scanning tools in use today is Nmap. Many connection attempts to different ports (services) may indicate a port scan.
Chapter 30 ADP 30.8.1.4 Filtered Port Scans A filtered port scan may indicate that there were no network errors (ICMP unreachables or TCP RSTs) or responses on closed ports have been suppressed. Active network devices, such as NAT routers, may trigger these alerts if they send out many connection attempts within a very small amount of time. These are some filtered port scan examples.
Chapter 30 ADP 30.8.2.3 TCP SYN Flood Attack Usually a client starts a session by sending a SYN (synchronize) packet to a server. The receiver returns an ACK (acknowledgment) packet and its own SYN, and then the initiator responds with an ACK (acknowledgment). After this handshake, a connection is established. Figure 343 TCP Three-Way Handshake A SYN flood attack is when an attacker sends a series of SYN packets. Each packet causes the receiver to reply with a SYN-ACK response.
Chapter 30 ADP 30.8.2.5 UDP Flood Attack UDP is a connection-less protocol and it does not require any connection setup procedure to transfer data. A UDP flood attack is possible when an attacker sends a UDP packet to a random port on the victim system. When the victim system receives a UDP packet, it will determine what application is waiting on the destination port.

CHAPTER 33 Device HA Use device HA and Virtual Router Redundancy Protocol (VRRP) to increase network reliability. See Section 5.4.8 on page 117 for related information on these screens. 33.1 Virtual Router Redundancy Protocol (VRRP) Overview Every computer on a network may send packets to a default gateway, which can become a single point of failure. Virtual Router Redundancy Protocol (VRRP) allows you to create redundant backup gateways to ensure that the default gateway is always available.
Chapter 33 Device HA " Every router in a virtual router must use the same advertisement interval. If Router A becomes unavailable, it stops sending messages to Router B. Router B detects this and assumes the role of the master router. This is illustrated below. Figure 364 Example: VRRP, Master Becomes Unavailable Router B is now using the IP address of the default gateway, and it is forwarding packets for the network. The loss of Router A has no effect on the network.
Chapter 33 Device HA 33.1.1 Additional VRRP Notes • It is possible to set up two virtual routers so that they back up each other. • VRRP uses IP protocol 112. 33.2 VRRP Group Overview In the ZyWALL, you should create a VRRP group to add one of its interfaces to a virtual router. You can add any Ethernet or VLAN interface with a static IP address. You do not configure VRRP groups for virtual interfaces. " You can only use interfaces that have static IP addresses.
Chapter 33 Device HA 33.2.1 Link Monitoring and Service Control With link monitoring enabled, a backup ZyWALL that takes over for an unavailable master ZyWALL takes over all of the master ZyWALL’s static IP addresses. This way the backup ZyWALL takes over all of the master ZyWALL’s functions. However, this also means you can no longer access the original master ZyWALL through one of its static IP addresses (because the backup ZyWALL now uses this address).

CHAPTER 40 Certificates This chapter gives background information about public-key certificates and explains how to use the Certificates screens. See Section 5.5 on page 122 for related information on these screens. 40.1 Certificates Overview The ZyWALL can use certificates (also called digital IDs) to authenticate users. Certificates are based on public-private key pairs. A certificate contains the certificate owner’s identity and public key.
Chapter 40 Certificates Certification authorities maintain directory servers with databases of valid and revoked certificates. A directory of certificates that have been revoked before the scheduled expiration is called a CRL (Certificate Revocation List). The ZyWALL can check a peer’s certificate against a directory server’s list of revoked certificates. The framework of servers, software, procedures and policies that handles keys is called PKI (public-key infrastructure). 40.1.
Chapter 40 Certificates " Be careful to not convert a binary file to text during the transfer process. It is easy for this to occur since many programs use text files by default. 40.4 Certificate Configuration Screens Summary This section summarizes how to manage certificates on the ZyWALL. Use the My Certificate screens to generate and export self-signed certificates or certification requests and import the ZyWALL’s CA-signed certificates.

Add icon Click the Add icon in the heading row to open a screen where you can add a new domain zone forwarder record. Refer to Table 202 on page 584 for information on the fields.
Chapter 43 System 43.5.4 Address Record An address record contains the mapping of a fully qualified domain name (FQDN) to an IP address. An FQDN consists of a host and domain name. For example, www.zyxel.com is a fully qualified domain name, where “www” is the host, “zyxel” is the second-level domain, and “com” is the top level domain. mail.myZyXEL.com.tw is also a FQDN, where “mail” is the host, “myZyXEL” is the third-level domain, “com” is the second-level domain, and “tw” is the top level domain.
Chapter 43 System 43.5.7 Domain Zone Forwarder A domain zone forwarder contains a DNS server’s IP address. The ZyWALL can query the DNS server to resolve domain zones for features like VPN, DDNS and the time server. A domain zone is a fully qualified domain name without the host. For example, zyxel.com.tw is the domain zone for the www.zyxel.com.tw fully qualified domain name. 43.5.8 Adding a Domain Zone Forwarder Click the Add icon in the Domain Zone Forwarder table to add a domain zone forwarder record.
Chapter 43 System 43.5.9 MX Record A MX (Mail eXchange) record indicates which host is responsible for the mail for a particular domain, that is, controls where mail is sent for that domain. If you do not configure proper MX records for your domain or other domain, external e-mail from other mail servers will not be able to be delivered to your mail server and vice versa. Each host or domain can have only one MX record, that is, one domain is mapping to one host. 43.5.

CHAPTER 45 File Manager This chapter covers how to use the ZyWALL’s File Manager screens to handle the ZyWALL’s configuration, firmware and shell script files. 45.1 Configuration Files and Shell Scripts Overview The File Manager screens allow you to store multiple configuration files and shell script files. When you apply a configuration file, the ZyWALL uses the factory default settings for any features that the configuration file does not include.
Chapter 45 File Manager While configuration files and shell scripts have the same syntax, the ZyWALL applies configuration files differently than it runs shell scripts. This is explained below. Table 215 Configuration Files and Shell Scripts in the ZyWALL Configuration Files (.conf) Shell Scripts (.zysh) • • • • • Resets to default configuration. Goes into CLI Configuration mode. Runs the commands in the configuration file. Goes into CLI Privilege mode. Runs the commands in the shell script.
Chapter 45 File Manager Lines 1 and 2 are comments. Line 5 exits sub command mode. ! this is from Joe # on 2006/06/05 interface ge1 ip address dhcp ! 45.1.2 Errors in Configuration Files or Shell Scripts When you apply a configuration file or run a shell script, the ZyWALL processes the file lineby-line. The ZyWALL checks the first line and applies the line if no errors are detected. Then it continues with the next line.
Chapter 45 File Manager You can change the way the startup-config.conf file is applied. Include the setenvstartup stop-on-error off command. The ZyWALL ignores any errors in the startupconfig.conf file and applies all of the valid commands. The ZyWALL still generates a log for any errors. 45.2 Configuration File Screen Click Maintenance > File Manager > Configuration File to open the Configuration File screen.

THIS SOFTWARE IS PROVIDED ``AS IS'' AND ANY EXPRESSED OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.
Appendix F Open Software Announcements This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below.
Appendix F Open Software Announcements For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License.
Appendix F Open Software Announcements 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change.
Appendix F Open Software Announcements However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables.
Appendix F Open Software Announcements It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7.
Appendix F Open Software Announcements 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13.

Appendix F Open Software Announcements right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3.
