2.7.2 Port Triggering
Port Triggering is a more secure feature than port forwarding. It only allows transient port

the private network, it will trigger the Residential Gateway to set up a temporary tunnel for an open
service port. The tunnel will not be closed until the packets stop passing through the Residential
Gateway for a period of time.
