8.2 The Port Forwarding Screen

Use the Port Forwarding screen to forward incoming service requests to the server(s) on
your local network.
You may enter a single port number or a range of port numbers to be forwarded, and the local
IP address of the desired server. The port number identifies a service; for example, web
service is on port 80 and FTP on port 21. In some cases, such as for unknown services or
where one server can support more than one service (for example both FTP and web service),
it might be better to specify a range of port numbers. You can allocate a server IP address that
corresponds to a port or a range of ports.
Please refer to RFC 1700 for further information about port numbers.
Configuring Servers Behind Port Forwarding (Example)
Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the
example), port 80 to another (B in the example) and assign a default server IP address of
10.0.0.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns
the WAN IP address. The NAT network appears as a single host on the Internet.

NOTE
Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web
or FTP server) from your location. Your ISP may periodically check for servers and may suspend your
account if it discovers any active services at your location. If you are unsure, refer to your ISP.
