Advanced Configuration

Setup Tab > Forwarding

The Forwarding screen allows you to set up port range forwarding and port triggering applications. Port range forwarding can be used to set up public services or other specialized Internet applications on your network, while port triggering can be used to set up triggered ranges and forwarded ranges for Internet applications.

Forwarding

Port Range Forwarding

Port forwarding can be used to set up public services on your network. When users from the Internet make certain requests on your network, the Router can forward those requests to computers 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.

NOTE: You must disable the Router’s DHCP function to use port forwarding.

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.

Service Select the Service you want.

IP Address Enter the IP address of the server that you want the Internet users to access.

On the Forwarding screen, click Add to List, and configure as many entries as you would like, up to a maximum of

30.To delete an entry, select it and click Delete selected application.

Port Triggering

Port triggering allows the Router to watch outgoing data for specific port numbers. The IP address of the computer that sends the matching data is remembered by the Router, so that when the requested data returns through the Router, the data is pulled back to the proper computer by way of IP address and port mapping rules.
