Setting Up Port Forwarding and Port Triggering

Use the Setup > Forwarding page if you need to allow public access to services on computers that are connected to the LAN ports. Port Forwarding opens a specified port or a port range for a service, such as FTP. Port Triggering opens a port range for services such as Internet gaming that use alternate ports to communicate between the server and LAN host. This page has the following sections:

•Port Range Forwarding, page 44

Port Range Forwarding

Port forwarding can be used to set up public services on your network. When users from the Internet make certain requests to your network, the router can forward those requests to computers that are equipped to handle the requests. If, for example, you set the port number 80 (HTTP) to be forwarded to IP address 192.168.1.2, then all HTTP requests from outside users will be forwarded to 192.168.1.2.

You may use this function to establish a web server or FTP server via an IP gateway. Make sure that you enter a valid IP address. (You may need to establish a static IP address in order to properly run an Internet server.) For added security, Internet users will be able to communicate with the server, but they will not actually be connected. The packets will simply be forwarded through the router.
