4.3.2 Port Triggering
Some applications require that specific ports in the Router's firewall be
opened for access by the remote parties. 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 party using the 'Triggering Ports'. The
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.
