Port Triggering
Some applications require specific ports in the gateway’s firewall to be open for access by remote parties. Port
Triggering 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 Gateway 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.
This is a list of specific ports in the gateway’s firewall that are open for access by remote parties.
