Port Triggering

Port triggering is an advanced feature that you can use to allow gaming and other Internet
applications that the firewall would otherwise block. You must know the port numbers the
application uses. Port triggering operates as follows:
1. A computer makes an outgoing connection using a port number defined in the Port
Triggering table.
2. The gateway records this connection, opens the incoming port or ports associated with this
entry in the Port Triggering List, and associates them with the computer.
3. The remote system receives the computer's request, and responds using a different port
number.
4. The gateway matches the response to the previous request, and forwards the response to
the computer. (Without port triggering, this response would be treated as a new connection
request rather than a response. As such, it would be handled in accordance with the port
forwarding rules.)
Note: Only one computer at a time can use port triggering. After a
computer finishes using a port triggering application, there is a short
time-out period before another computer can use the application.

To configure port triggering:
1. In the main menu, under Advanced, select Port Triggering.
