WPA Wi-Fi Protected Access (WPA) combines temporal key integrity protocol (TKIP) and 802.1x mechanisms.
CONFIGURING THE ADSL ROUTER 802.1X If 802.1x is used in your network, then you should enable this function for the ADSL Router. These parameters are used for the ADSL Router to connect to the authentication server. Parameter Description 802.1X Authentication Enable or disable this authentication function. Session Idle timeout Defines a maximum period of time for which the connection is maintained during inactivity.
ADVANCED SETUP Parameter Description Secret Key The secret key shared between the authentication server and its clients. NAS-ID Defines the request identifier of the Network Access Server.
CONFIGURING THE ADSL ROUTER NAT Network Address Translation allows multiple users to access the Internet sharing one public IP. Address Mapping Allows one or more public IP addresses to be shared by multiple internal users. This also hides the internal network for increased privacy and security. Enter the Public IP address you wish to share into the Global IP field. Enter a range of internal IPs that will share the global IP into the “from” field.
ADVANCED SETUP Virtual Server If you configure the ADSL Router as a virtual server, remote users accessing services such as web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the ADSL Router redirects the external service request to the appropriate server (located at another internal IP address).
CONFIGURING THE ADSL ROUTER Special Applications Some applications require multiple connections, such as Internet gaming, video-conferencing, and Internet telephony. These applications may not work when Network Address Translation (NAT) is enabled. If you need to run applications that require multiple connections, use these pages to specify the additional public ports to be opened for each application.

CONFIGURING THE ADSL ROUTER Route These pages define routing related parameters, including static routes and RIP (Routing Information Protocol) parameters. Static Route Click “Add” to add a new static route to the list. Parameter Description Network Address Enter the IP address of the remote computer for which to set a static route. Subnet Mask Enter the subnet mask of the remote network for which to set a static route. Gateway Enter the WAN IP address of the gateway to the remote network.
ADVANCED SETUP RIP Parameter Description General RIP Parameters RIP mode Globally enables or disables RIP. Auto summary If Auto summary is disabled, then RIP packets will include sub-network information from all subnetworks connected to the router. If enabled, this sub-network information will be summarized to one piece of information covering all subnetworks. Table of current Interface RIP parameter Interface The WAN interface to be configured.
CONFIGURING THE ADSL ROUTER Parameter Authentication Required Authentication Code Description • None: No authentication. • Password: A password authentication key is included in the packet. If this does not match what is expected, the packet will be discarded. This method provides very little security as it is possible to learn the authentication key by watching RIP packets. Password Authentication key. RIP sends routing-update messages at regular intervals and when the network topology changes.
ADVANCED SETUP Routing Table Parameter Description Flags Indicates the route status: C = Direct connection on the same subnet. S = Static route. R = RIP (Routing Information Protocol) assigned route. I = ICMP (Internet Control Message Protocol) Redirect route. Network Address Destination IP address. Netmask The subnetwork associated with the destination. This is a template that identifies the address bits in the destination address used for routing to specific subnets.
CONFIGURING THE ADSL ROUTER Firewall The ADSL Router’s firewall inspects packets at the application layer, maintains TCP and UDP session information including time-outs and the number of active sessions, and provides the ability to detect and prevent certain types of network attacks. Network attacks that deny access to a network device are called Denial-of-Service (DoS) attacks. DoS attacks are aimed at devices and networks with a connection to the Internet.
ADVANCED SETUP Access Control Access Control allows users to define the outgoing traffic permitted or not-permitted through the WAN interface. The default is to permit all outgoing traffic. The following items are on the Access Control screen: Parameter Description Enable Filtering Function Click Yes to turn on the filtering function. Normal Filtering Table Displays the IP address (or an IP address range) filtering table.

The MAC Filtering Table allows the ADSL Router to enter up to 32 MAC addresses that are not allowed access to the WAN port. Click Yes to enable, or No to disable this function. Enter the MAC address in the space provided.
CONFIGURING THE ADSL ROUTER URL Blocking The ADSL Router allows the user to block access to web sites by entering either a full URL address or just a keyword. This feature can be used to protect children from accessing violent or pornographic web sites. You can define up to 30 sites here.
ADVANCED SETUP Schedule Rule You may filter Internet access for local clients based on rules. Each access control rule may be activated at a scheduled time. Define the time schedule on this page, and apply the rule on the Access Control page.
CONFIGURING THE ADSL ROUTER Follow these steps to add a schedule rule: 1. Click “Add Schedule Rule”. 2. Define the appropriate settings for a schedule rule (as shown in this example). 3. Click “OK” and then click “SAVE SETTINGS” to save your settings.
ADVANCED SETUP Intrusion Detection • Intrusion Detection Feature Stateful Packet Inspection (SPI) and Anti-DoS firewall protection (Default: Enabled) — The Intrusion Detection Feature of the ADSL Router limits access for incoming traffic at the WAN port. When the SPI feature is turned on, all incoming packets will be blocked except for those types marked in the Stateful Packet Inspection section.
CONFIGURING THE ADSL ROUTER 4-46
ADVANCED SETUP • Stateful Packet Inspection This is called a “stateful” packet inspection because it examines the contents of the packet to determine the state of the communications; i.e., it ensures that the stated destination computer has previously requested the current communication. This is a way of ensuring that all communications are initiated by the recipient computer and are taking place only with sources that are known and trusted from previous interactions.
CONFIGURING THE ADSL ROUTER • Connection Policy Enter the appropriate values for TCP/UDP sessions as described in the following table. Parameter Defaults Description Fragmentation half-open wait 10 sec Configures the number of seconds that a packet state structure remains active. When the timeout value expires, the router drops the unassembled packet, freeing that structure for use by another packet.
ADVANCED SETUP • DoS Criteria and Port Scan Criteria Set up DoS and port scan criteria in the spaces provided (as shown below). Parameter Defaults Description Total incomplete TCP/UDP sessions HIGH 300 sessions Defines the rate of new unestablished sessions that will cause the software to start deleting half-open sessions. Total incomplete TCP/UDP sessions LOW 250 sessions Defines the rate of new unestablished sessions that will cause the software to stop deleting halfopen sessions.
CONFIGURING THE ADSL ROUTER DMZ If you have a client PC that cannot run an Internet application properly from behind the firewall, you can open the client up to unrestricted two-way Internet access. Enter the IP address of a DMZ (Demilitarized Zone) host on this screen. Adding a client to the DMZ may expose your local network to a variety of security risks, so only use this option as a last resort.
ADVANCED SETUP SNMP Use the SNMP configuration screen to display and modify parameters for the Simple Network Management Protocol (SNMP). Community A computer attached to the network, called a Network Management Station (NMS), can be used to access this information. Access rights to the agent are controlled by community strings. To communicate with the ADSL Router, the NMS must first submit a valid community string for authentication.
CONFIGURING THE ADSL ROUTER Trap Specify the IP address of the NMS to notify when a significant event is detected by the agent. When a trap condition occurs, the SNMP agent sends an SNMP trap message to any NMS specified as a trap receiver. Parameter Description IP Address Traps are sent to this address when errors or specific events occur on the network. Community A community string (password) specified for trap management.
ADVANCED SETUP ADSL ADSL (Asymmetric Digital Subscriber Line) is designed to deliver more bandwidth downstream (from the central office to the customer site) than upstream. This section is used to configure the ADSL operation type and shows the ADSL status.
