3.6.2.5 Port Trigger
Port triggering is a configuration option on a NAT -enabled router that allows a host machine to dynamically
and automatically forward a specific port back to itself. Port triggering opens an incoming port when your
computer is using a specified outgoing port for specific traffic. Port triggering does not require that you
know the computer’s IP address in advance. The IP address is captured automatically. Port triggering
requires specific outbound traffic to open the inbound ports, and the triggered ports are closed after a
period of no activity.
