Port Triggering
Some applications require that specific ports in the gateway's firewall be opened for access by remote parties. The Port Trigger fea-
ture dynamically opens up the open ports in the firewall when an application on the LAN initiates a TCP/UDP connection to a remote
party using the triggering ports. The gateway allows the remote party from the WAN side to establish new connections back to the
application on the LAN side using the Open Ports.
