NAT -- Port Triggering Setup 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 entries can be configured. Due to limited resources, port triggering feature has some limitation: sum of the outports of all configuration entries <= 1000 sum of the inports of one configuration entry <= 1000 Application Name Trigger Open WAN Interface Remove Protocol Port Range Protocol Port Range Start End Start End
