Internal Port  Enter the internal port number used by the server or Internet application. Check with the Internet application documentation for more information.

Protocol  Select the protocol used for this application, either TCP or UDP, or Both.

To IP Address  For each application, enter the IP address of the PC that should receive the requests. If you assigned a static IP address to the PC, then you can click DHCP Reservation on the Basic Setup screen to look up its static IP address.

Enabled  For each application, select Enabled to enable port forwarding.

Click Save Settings to apply your changes, or click Cancel Changes to cancel your changes.

Applications and Gaming > Port Range Forwarding

The Port Range Forwarding screen allows you to set up public services on your network, such as web servers, ftp servers, e-mail servers, or other specialized Internet applications. (Specialized Internet applications are any applications that use Internet access to perform functions such as videoconferencing or online gaming. Some Internet applications may not require any forwarding.)

When users send these types of requests to your network via the Internet, the Router will forward those requests to the appropriate servers (computers). Before using forwarding, you should assign static IP addresses to the designated servers (use the DHCP Reservation feature on the Basic Setup screen).

If you need to forward all ports to one computer, click the DMZ tab.

Applications & Gaming > Port Range Triggering

The Port Range Triggering screen 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.
