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.
