Port Triggering

Some applications require that specific ports in the firewall be opened for access by
the remote parties. Port Triggers dynamically '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.
