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.
