Port Triggering
Port triggering allows the router to watch outgoing data for a specific port number. The IP
address of the computer that sends the data is remembered by the router, so that when the
requested data returns through the router, the data will be passed to the specific computer by
way of IP address and port mapping rules. The router opens the port when the Port Triggering
happens. When the computer running the application stops sending the data through this port,
the router will close the port.
