9.3 Firewall – Port Triggers Configuration
Port triggering lets you set the router to watch outgoing traffic for specific port numbers,
remember the IP address of the sending computer, and then route the data back to the sending
computer when the requested data returns. This is typically used for online gaming and online
chat applications.
Port triggers allow virtual servers to be allowed when an outbound port is accessed.
