[. . . ] To have this function working properly, please run on router mode only, disable the DHCP server on the LAN port, and make sure the routing table has the correct routing entry. Figure 4-11 · DHCP Server IP for Relay Agent: Enter the DHCP server IP Address runs on WAN side. Note: If you select Disabled, the DHCP function will not take effect. 21 TD-8840T 4-port ADSL2/2+ Ethernet Router User Guide 4. 4 Advanced Setup Choose "Advanced Setup", you can see the next submenus: Figure 4-12 Click any of them, and you will be able to configure the corresponding function. 4. 4. 1 Firewall Choose "Advanced SetupFirewall" menu, and you will see the next screen (shown in Figure 4-13). Figure 4-13 Firewall: Select this option can automatically detect and block Denial of Service (DoS) attacks, such as Ping of Death, SYN Flood, Port Scan and Land Attack. SPI: If you enable SPI, all traffics initiated from WAN would be blocked, including DMZ, Virtual Server, and ACL WAN side. 4. 4. 2 Routing Choose "Advanced SetupRouting" menu, and you will see the routing information in the next screen (shown in Figure 4-14). 22 TD-8840T 4-port ADSL2/2+ Ethernet Router User Guide Figure 4-14 Click ADD ROUTE button to add a new route in the next screen (shown in Figure 4-15). Figure 4-15 Destination IP Address: This parameter specifies the IP network address of the final destination. The gateway is an immediate neighbor of your ADSL Router that will forward the packet to the destination. On the LAN, the gateway must be a router on the same segment as your Router; over Internet (WAN), the gateway must be the IP address of one of the remote nodes. Metric: Metric represents the "cost" of transmission for routing purposes. IP Routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks. Announced in RIP: This parameter determines if the ADSL router will include the route to this remote node in its RIP broadcasts. If set to Yes, the route to this remote node will be propagated to other hosts through RIP broadcasts. If No, this route is kept private and is not included in RIP broadcasts. 4. 4. 3 NAT Choose "Advanced SetupNAT" menu, you can setup the NAT (Network Address Translation) function for the Router (shown in Figure 4-16). 23 TD-8840T 4-port ADSL2/2+ Ethernet Router User Guide Figure 4-16 Virtual Circuit: Enter Virtual Circuit Index that you plan to setup for the NAT function. NAT Status: This field shows the current status of the NAT function for the current VC. You can go to the previous screen (shown in Figure 4-4) to activate the function. Number of IPs; This field is to specify how many IPs are provided by your ISP for current VC. Note: For VCs with single IP, they share the same DMZ and Virtual servers; for VCs with multiple IPs, each VC can set DMZ and Virtual servers. Furthermore, for VCs with multiple IPs, they can define the Address Mapping rules; for VCs with single IP, since they have only one IP, there is no need to individually define the Address Mapping rule. DMZ Choose "Advanced SetupNATDMZ" in Figure 4-16, you can configure the DMZ host in the next screen. A DMZ (demilitarized zone) is a host between a private local network and the outside public network. It allows outside users to access to a server that has company data directlly. Users of the public network outside the company can access to the DMZ host. Figure 4-17 DMZ Host IP Address: Enter the specified IP Address for DMZ host on the LAN side. Virtual Server Choose "Advanced SetupNATVirtual Server" in Figure 4-16, you can configure the Virtual Server in the next screen. 24 TD-8840T 4-port ADSL2/2+ Ethernet Router User Guide The Virtual Server is the server or server(s) behind NAT (on the LAN), for example, Web server or FTP server, that you can make visible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world. Figure 4-18 Rule Index: The Virtual server rule index for this VC. [. . . ] User Name/Password: Enter the User Name and password to login the ACS server. User Name/Password: Enter the User Name and Password that provided the ACS server to login the router. If Activated, the information will be informed to ACS server periodically. Interval: Enter the interval time here. 4. 6 Maintenance Choose "Maintenance", you can see the next submenus: Figure 4-36 Click any of them, and you will be able to configure the corresponding function. 4. 6. 1 Administration Choose "MaintenanceAdministration", you can set new password for admin in the screen (shown in Figure 4-37).
