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 Gateway 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.

Triggering
The Port Range Triggering screen allows the Gateway to

address of the computer that sends the matching data is
remembered by the Gateway, so that when the requested
data returns through the Gateway, the data is pulled back
to the proper computer by way of IP address and port
mapping rules.
