Server List (Port Forwarding) NQG_025 With NAT enabled, the IP addresses of nodes on your LAN are private since they are hidden from the Internet. IP Servers let you pass specific types of network traffic through the Netopia router's NAT interfaces. Once configured, selected types of network traffic, such as FTP requests or HTTP (Web) connections, will be forwarded to a specific host or server behind the Netopia router. Please Note: From the LAN (Local Area Network), you will also be able to access the servers that are responding to requests from the internet, but only using the internal private IP address. Access via the public IP address is not supported from a local ethernet connection. If your ISP is routing you multiple public IP addresses, you can also configure the router to forward all ports in one public IP to a designated private IP address on your LAN via Easy PAT List entries. For those instructions, see Quick Guide NQG_024: IP Mapping (Address Forwarding).
Please Note: If your router is currently running Netopia Residential Firmware with a web "GUI" configuration menu, this technote is not applicable to you. Most 3300 Series Netopia Gateways can be upgraded to Enterprise level firmware. Click Here! to purchase the upgrade key.

Before You Start
Telnet into the Netopia router's Main Menu at 192.168.1.1 (if using the default IP setting). If your network has a different IP addressing scheme, modify this accordingly. Click Here! for instructions on using telnet and Hyperterminal (serial connection).
Login with the user name and password. The Superuser login is required to save changes. If you are unsure of this, contact your network administrator.
Don't forget to press the Enter key to save any entries. Hitting the back space, delete or tab without first hitting enter will undo any changes.
The Esc key will take you back towards the main menu screen.
Once you have completed your configuration, you should reboot the Netopia to save and apply your changes.

Server List Configuration

1. From the Main Menu of router console screens, go to Quick Menus, and select Network Address Translation.
2. Select Show/Change Server List.
3. Select Easy-Servers.
4. From the Show/Change NAT Server List screen, select Add Server.
5. Select Service and the service and port you want to allow. If your service and port are not available in the pull-down menu, select Other. Selecting Other will allow you to enter a specific service port or a range of ports since fields are provided for both a First Port Number and a Last Port Number. To allow a specific service port, the First Port Number and Last Port Number should be the same. Select Okay.
6. Next, enter the Server Private IP Address, or the private IP address of the host/server you are forwarding the service to, and the Public IP Address you want to associate with the same host/server. This value can be left set to 0.0.0.0 if you are using the WAN IP as the Public IP address. Note: If your ISP is routing you multiple static IP addresses, other then the one used for Internet access, you may create more than one server for specific service as long as all servers have a different Public IP Address specified. For example, with two web servers on your LAN you would need to create two Server List entries for TCP 80 (www-http). Since each specific port (service) can only be mapped once using any given Public IP Address, a distinct public address must be used for each TCP 80 server list entry. It is not necessary for you to specify more than one Local WAN IP Address or Public IP Address in your router's configuration. As long as you are connecting to your ISP via a public IP address used for NAT, they are responsible for routing all other IP addresses via that connection.
   

Conclusion
You have now configured your router for TCP/UDP port forwarding. If you have a switched connection (ISDN or Analog), you will need to either disconnect and reconnect your Internet connection, or restart your router for the Nat Server List changes to take effect. If you wish to filter traffic for your static IP mappings, please see the following Netopia Technote:
