Port Forwarding
The Port Forwarding option gives Internet users access to services on your LAN. This
feature is useful for hosting online services such as FTP, Web or game servers. For
each entry, you define a public port on your router for redirection to an internal LAN IP
Address and LAN port. This option is used to open multiple ports or a range of ports
in your router and redirect data through those ports to a single PC on your network.
This feature allows you to enter ports in the format, Port Ranges (100-150),
Individual Ports (80, 68, 888), or Mixed (1020-5000, 689). This option is only applicable to the INTERNET session.
