Port Forwarding
Port Forwarding 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. When users send this type of request to your network via the
Internet, the router will forward those requests to the appropriate PC. If you want to forward a
whole range of ports, see Port Range Forwarding.

Port Range Forward
Port Range Forwarding 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

Internet, the router will forward those requests to the appropriate PC. If you only want to forward
a single port, see Port Forwarding.
