IP Address Settings and Computer Settings In order to install the DFL-600 you will need to check your computer’s settings and the values from your ISP.
Introduction and Overview The DFL-600 Firewall/VPN Router creates two separate networks on the LAN side of your network − by default, a 192.168.0.0 subnet and a 192.168.1.0 subnet (both with a subnet mask of 255.255.255.0). The DFL600 routes packets between these two subnets and the Internet (or the network connected to the DFL-600’s WAN port). An Internet Service Provider (ISP) or a network administrator provides the network address information on the WAN network. The 192.168.0.0 network − LAN.
The DMZ port is used to allow computers and devices connected to this port to have more direct access to the Internet. This is useful for certain applications that may conflict with the firewall and Network Address Translation (NAT) features of the DFL-600. Computers and devices connected to the DMZ port will not have the level of protection that the LAN ports can provide, however.
address, subnet mask, default gateway address, and primary and (optional) secondary DNS addresses. This information will be provided by your ISP. Point-to-Point Protocol over Ethernet (PPPoE) − this protocol requires the use of a Username and Password to gain access to the network. In addition, you can specify a Connect on Demand connection that will connect to the Internet only when a computer or device on your LAN makes a request, or when the DFL-600 is rebooted.
Using the Configuration Utility Launch your web browser and type the device IP address (https:// 192.168.0.1) in the browser’s address box. This is the default IP address of your DFL-600. Press Enter. The following dialog-box will appear to prompt you to enter the DFL-600’s default User Name and Password. The DFL-600’s default User Name is admin and the default Password is also admin − all lower case. Click OK to open the Home menu.
The Setup Wizard will guide you the most basic setup tasks, such as setting an administrative password, selecting the type of WAN connection you have, entering your computer’s host name (if required by your ISP), saving the configuration and restarting the router. All other setup tasks can be accomplished using the configuration utility from your web browser. To use the Setup Wizard, click on the Run Setup Wizard link. This will start the Setup Wizard.
Setup Wizard The Setup Wizard will guide you through the most basic setup tasks for the DFL-600. All other configuration tasks can be accomplished through the web-based manager. The Home menu contains a Run Setup Wizard link. Click on this button to run the Setup Wizard. Click Next to continue.
Enter a password in the Password field, and again in the Verify Password field. This will become the logon password for the DFL-600. This password is case-sensitive, so remember to use capital letters when logging on to the DFL-600’s web-based manager − if you enter a password with capital letters here. The user name, admin, will not be changed here. Note: If you choose to input a password, please remember it.
This menu allows you to select the type of connection your ISP provides. Many ISPs use the PPPoE (Point-to-Point Protocol over Ethernet) for DSL connections, while many Cable ISPs use DHCP (Dynamic Host Configuration Protocol). DHCP assigns an IP address for your Internet connection each time you log on (and is therefore, a dynamic IP address). DHCP is referred to as Dynamic IP address on the DFL-600.
Some ISPs require you to use an assigned host name for your Internet connection. If your ISP requires this, you can enter the assigned host name in the Host Name field. If you selected Static IP Address on the Select Internet Connection Type (WAN) wizard screen above, the following screen will open: This screen will allow you to enter the static IP address information, if your ISP has assigned a static IP address to your Internet account. Your ISP must provide this information.
This screen will allow you to enter the PPPoE information, if your ISP uses the PPPoE protocol for your Internet account. Your ISP must provide this information. Click Next to continue.
You have completed the basic setup Wizard. The configuration now needs to be entered into the DFL-600’s non-volatile RAM. Clicking Restart will save the configuration to non-volatile RAM and restart the router.
Home The Home menu contains links to all of the setup menus for the DFL-600.
WAN Settings The WAN Settings menu allows you to view the current configuration for your DFL-600, and to choose the protocol by which your DFL-600 will receive its WAN network settings. The settings listed under WAN Settings are the network settings currently in use by the DFL-600. The fields where you will enter the WAN Settings will change depending upon the choice you make in the IP Settings Mode dropdown menu. These settings are described below.
IP Settings Mode This drop-down menu determines how the DFL600 will obtain its IP address information. The fields where you will enter the information will change, as appropriate, to reflect the mode you have selected. The page shown above is in Dynamic mode. Dynamic allows the DFL-600 to get its IP address information from your ISP using the Dynamic Host Configuration Protocol (DHCP). Use this setting if your ISP instructs you to use DHCP or to automatically obtain an IP address.
Default Gateway Primary DNS Server Secondary DNS Server This is the IP address of a device at your ISP’s office where packets destined for the Internet − from your home network − are sent, before being forwarded to their final destination. For the DFL-600, the Default Gateway address is provided by your ISP. For computers on your home network, their Default Gateway is the IP address of your DFL-600.
MAC address when connecting to the cable modem. Clicking on the Clone button will enable this function. Remember to click the Apply button and then to save the changes using Tools, System, and the Save button.
Static IP Address − If your ISP has assigned you an IP address that will never change, choose this option.
PPPoE − If your ISP uses Point-to-Point Protocol over Ethernet (PPPoE), choose this option. When this option is chosen, the following fields appear to allow you to enter the network address information: Connect on Demand − allows the PPPoE WAN connection to be active only when a computer on your LAN makes a connection request. This is similar to the way a dial-up modem initiates a connection.
LAN Settings The LAN Settings allows you to view the current IP address and subnet mask assigned to the DFL-600. It also allows you to change these settings. If it is necessary to change the IP Address or Subnet Mask assigned to the DFL-600, enter the new values in the appropriate fields, and press Apply to make the changes current.
As an example, if your LAN network is to be a 192.168.0.x network with a subnet mask of 255.255.255.0, you might assign the DFL-600 an IP address of 192.168.0.1 and configure the DFL-600’s DHCP server to assign addresses in the range between 192.168.0.2 to 192.168.0.100. The default gateway setting for computers on the LAN side will be the DFL-600’s IP address − in this case, 192.168.0.1.
DHCP Settings DHCP (Dynamic Host Configuration Protocol) is a method of automatically assigning IP addresses, subnet masks, default gateway and DNS server IP address to computers on the LAN side of the DFL-600. The DFL-600 can be a DHCP server for your LAN, assigning IP addresses, etc. to computers on your network from a range of addresses you specify below. DHCP Server Status Starting IP Address This allows you to Enable or Disable the DHCP Server feature on the DFL-600. The default is Enabled.
the IP address assigned to the DFL-600 be contained in the range of IP addresses available for the DFL-600 to assign. In this case, the IP address of the DFL-600 is 192.168.0.1, so the first IP address in the range is 192.168.0.2. Ending IP Address Lease Time Auto Configuration IP addresses can range from 0.0.0.0 to 255.255.255.255, but in the DFL-600’s default IP addressing scheme, the range is from 192.168.0.0 to 192.168.0.255.
Domain Name Primary DNS Server Secondary DNS Server The DFL-600 can provide a domain name to computers on your network. This domain name suffix can be provided automatically by your ISP, or you can enter it statically here. This suffix will then be automatically added to URL requests for access to your ISP’s servers. This is the IP address of a server on the Internet that provides the service of changing text URLs into IP address for sites on the Internet.
MAC Address IP Address DHCP Client This is the MAC address of the PC you want to assign the IP address specified below using DHCP. This is the IP address you want to assign the PC identified by its MAC address above, using DHCP. This identifies the PC as either a DHCP client or not. This allows you to check to see if the specified MAC address has already been assigned an IP address using DHCP.
NAT Network Address Translation Note: NAT is automatically applied between the WAN and the LAN sides of the DFL-600. It does not require any user configuration. Network Address Translation (NAT) is a routing protocol that allows your network to become a private network that is isolated from, yet connected to the Internet.
DMZ NAT and the firewall features of your DFL-600 may conflict with certain interactive applications such as video conferencing or playing Internet video games. For these applications, a bypass can be set up using the DMZ port and a corresponding DMZ IP address. The DMZ IP address is “visible” to the Internet (or WAN) and does not benefit from the full protection of the NAT function.
DMZ Settings The DMZ Settings screen allows you to Enable and Disable the DMZ port on the DFL-600 and to specify the IP address and Subnet Mask that the DMZ port will use. The default DMZ IP address is 192.168.1.1 with a subnet mask of 255.255.255.0. IP Address Subnet Mask This is the IP address assigned to the DMZ port, and will be assigned to a PC that you connect to this port. You can assign any IP address to the DFL-600’s DMZ port that is within the range 192.168.1.1 to 192.168.1.254.
to connections to the WAN or Internet. The IP address must be from the same range as the IP address of the DMZ port. The default DMZ IP address is 192.168.1.1, so DMZ Servers must be from the IP address range from 192.168.1.2 to 192.168.1.254, with a subnet mask of 255.255.255.0. DMZ host IP address This is the IP address you have assigned to your DMZ computer. You will need to manually configure the IP address settings for each computer you connect to the DFL-600's DMZ port.
Time Settings The DFL-600 can be set to obtain and distribute the correct time to computers on your LAN using the Simple Network Time Protocol (SNTP). Click on the Time button to open the following page: System Date Time Time Zone Time Set Type Displays the current system date and time. This drop-down menu allows you to select the time zone in which your DFL-600 is located. This drop-down menu allows you to specify the method the DFL-600 will use to obtain the date and time.
Set Type IP address Domain Name YYYY-MM-DD HH:MM:SS This drop-down menu allows you to select either the IP address of an SNTP server, or the Domain Name (URL) of an SNTP server that the DFL600 will contact to obtain the correct date and time. Enter the IP address of an SNTP server here. Enter the Domain Name (URL) of an SNTP server here. These fields allow you to manually enter the date using a year-month-day format. These fields allow you to manually enter the time using an hour: minute: second format.
Clicking the Enable click box, opposite the User Control table entry, will open the rest of the User Management page, including the Bandwidth control and Management Type table entries.
User Control Logout Timer Bandwidth Management Type This allows you to enable or disable the authentication of users on the LAN side of the DFL-600, without changing the configuration settings. This is useful when you need to troubleshoot Internet access problems for PCs on your LAN. You can enter a maximum amount of time that users are allowed to be “logged in”. When a user is logged in for a period of time longer than that specified here, they must log in again.
Clicking the Add Users link will open the following page: Add Users User name Password This allows you to add User names and Passwords for users on your LAN. In the Local mode, the DFL-600 authenticates users based upon the User name and Password entered here. Enter a User name here. Enter a Password corresponding to the User name entered above. POP3 The Post Office Protocol, version 3 (POP3) is used to access and retrieve email from a mailbox on a server that is usually located at your ISP’s facility.
POP3 Server IP Server Port The Post Office Protocol, version 3. This is used to view and retrieve e-mail from a POP3 server on the WAN. Enter the IP address of your POP3 server here. Your ISP should provide you with this address. This is the TCP port number that the POP3 server will use to communicate with PCs on your LAN. TCP port 110 is the ‘well known’ or default port used for the POP3 protocol.
If you have some PCs (or other network devices) that do not require RADIUS user authentication to access the WAN (Internet), you can enable 802.1x, and then enter the IP Address and IP (subnet) Mask of these devices under the Edit link (which will appear when you enable 802.1x). PCs and network devices that have their IP Address and IP (subnet) Mask entered on the 802.
RADIUS 802.1X Server IP Authentication Port Accounting Port The Remote Access Dial-in User Service (RADIUS) is one of the most common protocols used to carry authorization, authentication, and configuration information between a RADIUS server on the WAN and PCs on your LAN. Choosing RADIUS will allow the DFL-600 to connect PCs on your LAN to a RADIUS server on the WAN. 802.1x is a standard for passing the Extensible Authentication Protocol (EAP) packets over a LAN.
Secret Key Accounting Service Authentication Method RADIUS server will use to connect to PCs on your LAN for the RADIUS accounting function. The default port number for accounting is 1813. Enter the shared key used between PCs on your LAN and the RADIUS server. Use the drop-down menu to enable or disable the RADIUS accounting service. Use the drop-down menu to enable or disable the RADIUS accounting service. Clicking the 802.1x Enable click-box, and then Edit link will open the following page: 802.
Clicking on the Edit link (which appears when you enable 802.1x) will open the 802.1x Device Configuration page, as shown below. If you have PCs on your LAN that do not require RADIUS user authentication to access the Internet (or other networks through your ISP), you can use Enable 802.1x, and then click the Edit link. This will allow you to enter the IP Address and IP (subnet) Mask of PCs on your LAN that need to bypass the RADIUS user authentication.
802.1X 802.1x is a standard for passing the Extensible Authentication Protocol (EAP) over a LAN. You should enable this only if there are 802.1x devices between the DFL-600 and the RADIUS server on the WAN. Clicking on the Edit link (which appears when you enable 802.1x) will open the 802.1x Device Configuration page, as shown below. Use this table to enter the IP Address and IP Mask The DFL-600 supports only 802.1X pass through. This means that the DFL-600 will forward 802.
Clicking the LDAP click box will open the following page: LDAP Server IP Server Port Base DN Enter the IP address of your LDAP server here. Your ISP should provide you with this address. This is the TCP port number that the LDAP server will use to communicate with PCs on your LAN. Port 389 is the ‘well known’ or default port used for LDAP, while Secure LDAP uses port 636. This is the Distinguished Name used for LDAP.
Advanced Settings NAT Network Address Translation Network Address Translation (NAT) is a routing protocol that allows your network to become a private network that is isolated from, yet connected to the Internet. It does this by changing the IP address of packets from a global IP address − assigned by your ISP − usable on the Internet to a local IP address − assigned by you − usable on your private network (but not on the Internet.
Private IP Transport Type This is the IP address of the server on your LAN that will provide the service to remote users. You can select the transport protocol (TCP or UDP) that the application on the virtual server will use for its connections. The choice of this protocol is dependent on the application that is providing the service. If you do not know which protocol to choose, check your application’s documentation.
Application Gateway (ALG) Some applications (programs running on a PC on your LAN) require multiple TCP or UDP ports to function properly. Applications such as Internet gaming, video conferencing, and Internet telephony are some examples of applications that often require multiple connections. These applications often conflict with NAT, and therefore require special handling.
Trigger Type Max Activity Interval Session Chained Address Replacement Replacement Format Allow sessions initiated from/to 3rd host Popular Applications single port, or a range of ports. If only a single port is used, enter the same port number in both the starting and ending port number fields. This is the protocol (TCP or UDP) that the application uses to make the connection. This is the maximum interval, in milliseconds, between the triggering of a protocol session and the protocol’s dynamic session.
firmware and can be selected here from the dropdown menu. Selecting one of the listed applications is the equivalent of entering the correct settings in the fields above for the specific application. For example, the Netmeeting application requires a Trigger Port Range of 1720 – 1720, a Trigger Type of TCP, and so on. The correct settings for the applications listed in this drop-down menu have been entered into the DFL-600’s firmware, for your convenience.
Destination IP Network Subnet Mask Gateway IP Address This is the IP address of the remote network that the DFL-600 will route service requests to. This is the corresponding subnet mask for the remote network. This is the IP address of the gateway on the remote network that will provide the connection between your DFL-600 and servers on the remote network. Dynamic Routing Your DFL-600 can automatically discover routes to destinations on both your LAN and the WAN (Internet).
Rip Version RIP Enabled Interface Your DFL-600 can automatically discover routes to destinations on both your LAN and the WAN (Internet). You can choose either RIP1, RIP2 or None. RIP2 (Routing Information Protocol version 2) adds support for variable-length subnet masks, and is generally the best choice. Choosing None will disable the routing function of your router, as will choosing Disabled for the WAN or LAN RIP interface.
Network Address Subnet Mask Interface Name Multicast Support Update Timer Timeout Timer Garbage Collection Timer LAN RIP interface will disable the routing function of your router. This is the IP address of either the LAN or WAN side of your DFL-600. This is the subnet mask corresponding to the Network Address above. This is the name of the interface corresponding to the Network Address above. You can enable or disable multicast support. It is recommended that you enable this feature.
In the case shown above, the DFL-600’s WAN port was connected to a 10.0.0.0 network − with a subnet mask of 255.0.0.0. The LAN ports used the default 192.168.0.0 network addresses, and the DMZ port used the default 192.168.1.0 network addresses − both with a subnet mask of 255.255.255.0. The 0.0.0.0 IP address signifies the Broadcast address − the address within the DFL-600 where all packets that have an unknown destination address are forwarded. The DFL-600 then relates the 0.0.0.
Policy (Firewall) Configuration Some Examples Your DFL-600 allows you to make policy rules and then group these rules into a policy that will limit the types of access PCs on your LAN can have to the WAN (Internet). In addition, you can create a Schedule that will determine at what times and days of the week these policies are enforced.
A schedule called NoWeekDays has been entered with the hours between 6 pm and 9 pm checked for the weekdays Monday through Friday. Click on the Apply button to enter this schedule into the Schedule Table. You can enter up to 15 Schedules, but two default schedules are automatically maintained by the DFL-600 − Always and None. You can make changes to the None Schedule, but the Always Schedule is intended for policies that should always be enforced.
You can change the times and days entered for a Schedule by clicking on the link below the Schedule View heading. This will open the Schedule Rules page for the corresponding Schedule Name, and allow you to make changes. Setting the Policy Rules Now you need to configure the DFL-600 to block PCs on your LAN from accessing Web-pages on the WAN (Internet). To do this, click on the Policy button to open the Policy Rules page, as shown below. Enter a name for this rule in the Rule Name field.
range to PCs that you want the Policy Rule to apply to, and leave PCs with IP addresses outside the range free to access web-pages on the WAN (Internet). For simplicity in this example, we are going to specify Any in both the Source IP Range and Destination IP Range fields. This will mean that any PC on your LAN will be denied access to web-pages on the WAN (Internet) regardless of that PC’s IP address.
Now that the Policy Rule − Block Web − is configured, we want to add this Policy Rule to a Policy group. Click on the Policies link to open the Policy Add page, as shown below.
Enter a name for the Policy group in the Policy Name field. This name will be used to reference this Policy group. In this case, we have named this Policy group StudyTime. The schedule we created previously will appear in the Assign to Schedule drop-down menu and is selected as the times and days of the weed this Policy will be enforced. We want to deny access to PCs on our LAN, so in the Action drop-down menu, we select Deny.
Under the Rule Filter heading, click Enabled, and then click the “Outbound Firewall Rule” link. This will open a page that contains all of the Policy Rules that apply to Outbound packets, as shown below.
Click the box under the Add heading to add the BlockWeb Policy Rule to the StudyTime Policy group. Click the Apply button to make the entry current. Click the Back button to return to the Policy Add page. Setting the Policy Global Status Now we need to configure the Global Policy Status. Click the Global Policy Status link − from the Policy Add page − to open the following page.
For the BlockWeb Policy Rule and the StudyTime Policy group, we need to set the Outbound Port Filter to Enabled − by clicking the Enabled clickbox − and to select the Allow all except policy settings option. When Allow all except policy settings is selected, the DFL-600 will drop (filter) packets that meet the criteria established in the Policy Rules (in this case, HTTP packets). All other packets will be forwarded to their destination.
Remember to save the Policy configuration into the DFL-600’s non-volatile RAM using the Save button (under the Tools tab, click the System button to see the Save options). This will ensure that the DFL-600 will retain the Policy configurations when it is restarted or if the AC power is interupted. Example 2 − Limiting Access to Internet Domains Policy Rules The DFL-600 allows you to specify rules that it will use to limit access (filter packets) to and from PCs on your LAN.
Enter a name for the policy rule you want to configure in the Rule Name field. This name will appear in the Service Rules table, along with all of the parameters you specify for the rule, and is used to identify and reference the rule on subsequent web pages, as described below. In the case shown above, a rule called notelnet has been entered to block telnet packets from coming in from the WAN to the LAN.
The next step is to specify if you want the policy rule to apply to Inbound or Outbound packets. Inbound here means from the WAN to your LAN, while Outbound means from your LAN to the WAN. The Direction drop-down menu allows you to choose which direction the DFL-600 will filter packets that meet the criteria of the policy rule.
Policy Status page, “Default allow all” means that the DFL-600 will allow all packets except those that meet the criteria established in the policy rules. “Default deny all” means that the DFL-600 will deny (filter) all packets except those that meet the criteria established in the policy rules. Policies − Policy Add Once you have defined what type of packets you want the DFL-600 to look for, you need to assign those rules to a policy.
Enter a name for the new group of policy rules in the Policy Name field. This name is used to reference the group of policy rules. You can also assign this group of policy rules to a schedule (which is either Always or a schedule you can create below). Finally, you can choose to Allow or Deny access. Blocking Internet Domains The DFL-600 will allow you to make a list of Domain names for which packets will be filtered. Clicking on the Domain Add link on the Policy Rules page will open the following page.
Enter a domain name you want to limit access to in the Domain Name field. Click the Apply button to add this domain name to the list. Blocking Keywords The DFL-600 will allow you to make a list of keywords for which packets will be filtered Clicking on the Keywords Add link on the Policy Rules page will open the following page. Enter a key word you want the DFL-600 to examine packets for in the Key Word field. Click the Apply button to enter this key word into the list.
Blocking MAC Addresses The DFL-600 will allow you to make a list of MAC addresses for which packets will be filtered. MAC (Media Access Control) addresses are the physical addresses that are assigned to networking devices by their respective manufacturers. These addresses are 12 hexadecimal digits long and are in the form 01-23-45-67-89-AB − where the numerals 0-9 and the letters A-F are used. Clicking on the MAC Add link on the Policy Rules page will open the following page.
IPSec Settings IPSec (IP Secure) is a group of IP extensions developed by the Internet Engineering Task Force (IETF) to provide security services that are compatible with the existing IP standard. IPSec provides authentication, integrity, access control, and confidentially. The data and information exchanged between two ends of an IPSec connection can be encrypted and verified. Virtual Private Network (VPN) Tunnels can be created to allow encrypted and secured communication across networks or the Internet.
IPSec Pass-through IPSec Status Click Enable to allow IPSec packets to pass through the router to the destination computer on your LAN. When IPSec Pass-through is enabled, the DFL-600 will allow IPSec packets to reach their destination computer on your LAN. Click Enable to make the IPSec settings active. Manual Key Settings There are two methods for exchanging the encryption/decryption keys required by IPSec − Manual Key entry and Internet Key Exchange (IKE).
SPIs to maintain the IPSec connection. An IKE VPN is generally considered more secure than a Manual Key VPN because IKE can generate new keys and SPIs randomly during the negotiation phase. To configure a Manual Key VPN, click the Manual Key link to open the page shown below.
Add/New Tunnel Tunnel ID Termination IP Shared Key Local SPI Remote SPI IPSec Operation The following fields will identify the Manual Key VPN tunnel on the DFL-600. An alphanumeric string that identifies the remote tunnel. A sting of up to 63 characters can be entered. The Tunnel ID is sometimes called the Negotiation ID of the remote gateway. The IP address of the remote gateway. The encryption key that should be entered exactly the same way on both endpoints in order to establish Phase 1 negotiation.
ESP Transform This drop-down menu allows you to select the encryption algorithm that will be used when ESP is selected in the IPSec Operation dropdown menu above. You can choose between Null − no encryption, DES − using DES encryption, and 3DES − using triple DES encryption. Encryption Key (ASCII) ESP Auth You must select the exact same ESP transform (encryption algorithm) on both ends of a VPN tunnel. Enter the predetermined alphanumeric Encryption key.
AH Transform Authentication key on both ends of a VPN tunnel. This drop-down menu allows you to select the authentication method that will be used when AH is selected in the IPSec Operation dropdown menu above. You can choose between MD5 − using MD5 message digest authentication, and SHA − using the SHA authentication method. You must select the exact same AH authentication method on both ends of a VPN tunnel. AH Auth Key (ASCII) Enter the predetermined alphanumeric AH Authorization key.
Subnet Mask Enter the subnet mask corresponding to the IP address range entered above. Tunnel Settings − IPSec There are two methods for exchanging the encryption/decryption keys required by IPSec − Manual Key entry and Internet Key Exchange (IKE). The difference between Manual Key and IKE is how the encryption keys and SPI are determined. The Tunnel Settings page on the DFL-600 allows you to configure IKE for an IPSec VPN tunnel.
Add/New Tunnel Tunnel Name Peer Tunnel Type The following fields will identify the VPN tunnel on the DFL-600. Enter a name by which this IPSec VPN tunnel configuration can be referrenced.
this VPN tunnel will connect with using this drop-down menu. Static IP address allows you to specify the IP address of the remote end of the VPN tunnel − assuming that this IP address does not change (is statically assigned by the remote peer’s ISP). Domain Name allows you to specify the domain name of the remote end of the VPN tunnel. This requires that the designated DNS server for the DFL-600 be able to resolve the specified domain name into an IP address.
Sting(FQDN) − This allows you to specify that the “fully-qualified domain name” of the remote end of the IPSec VPN tunnel will be used to identify and authenticate the remote host. Peer ID Shared Key Phase 1 Proposal Phase 2 Proposal Target Host Range Starting Target Host Email(UFQDN) − This allows you to specify that the E-mail address of the remote end of the IPSec VPN tunnel will be used to identify and authenticate the remote host.
IP addresses of computers on the remote LAN that will be allowed to access the VPN.
