6.3.2 Port Triggering

Note: This option is not available for Bridge mode.

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.
