Port Triggering

Port triggering allows some applications to function correctly that would otherwise be partially blocked by the firewall. Using this feature requires that you know the port numbers used by the Application.

Once configured, operation is as follows:

A PC makes an outgoing connection using a port number defined in the Port Triggering table.

This Router records this connection, opens the additional INCOMING port or ports associated with this entry in the Port Triggering table, and associates them with the PC.

The remote system receives the PCs request and responds using the different port numbers that you have now opened.

This Router 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.

Only 1 PC can use a Port Triggering application at any time.
