[. . . ] 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. Enter a number that approximates the cost for this link. The number need not to be precise, but it must between 1 and 15. In practice, 2 or 3 is usually a good number. 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. All the VCs with single IP will use the same Virtual Server rules. [. . . ] 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). 43 TD-8840T 4-port ADSL2/2+ Ethernet Router User Guide Figure 4-37 Note: 1) 2) There is only one account that can access Web-Management interface. The default account is "admin", and the password is "admin". When you change the password, you should enter the new password twice, and then click SAVE to make the new password take effect. 4. 6. 2 Time Zone Choose "MaintenanceTime Zone", you can configure the system time in the screen (shown in Figure 4-37).
