Port Triggering

The Port Triggering screen allows the Router to watch outgoing data for specific port numbers. The IP address of
the computer that sends the matching data is remembered by the Router, so that when the requested data
returns through the Router, the data is pulled back to the proper computer by way of IP address and port mapping
rules.
