6.3.2 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.
To add a Trigger Port, simply click the Add button. The following will be displayed.
