Once configured, port triggering operation is as follows:
1. A PC 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 PC.
3. The remote system receives the PCs request, and responds using a different port number.
4. The gateway matches the response to the previous request, and forwards the response to the
PC. (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 PC can use a port triggering application at any time. After a PC has
finished using a port triggering application, there is a short time-out period before
the application can be used by another PC.
To configure port triggering:
1. Log in to the gateway as described in
2. In the main menu, under Advanced, select Port Triggering to display the following screen:
