Applications & 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.
If you need to forward all ports to one computer, click the

DMZ tab.
