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; refer to DHCP Reservation, page 7). If you need to forward all ports to one computer, click the DMZ tab. Advanced Configuration Port Range Forwarding To forward a port, enter the information on each line for the criteria required.
