6.3.2 Port Triggering
Some applications require that specific ports in the firewall be opened for access by
remote parties. Port Triggering dynamically opens the 'Open Ports' in the firewall
when an application on the LAN initiates a TCP/UDP connection to a remote party
using the 'Trigger 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 of 32 entries can be configured.
To add a Trigger Port, click the Add button. The following screen will display.
