Some applications require that specific ports in the modem router's firewall should be opened for
access by remote devices. Port Trigger dynamically opens up the 'Open Ports' in the firewall when
an application on the LAN initiates a TCP/UDP connection to a remote device using the triggering
ports. The modem router allows the remote party from the WAN side to establish new connections
back to the application on the LAN side using the open ports. A maximum 32 entries can be
configured.
