Application Rules

To access the Application Rules window, click the Application Rules button in the Advanced directory.
Some applications require that the remote parties open specific ports in
the Router's firewall for access. Port Trigger dynamically opens the Open
Ports in the firewall when an application on the LAN initiates a TCP/UDP
connection to a remote party using Trigger Ports. The Router allows the
remote party form the WAN side to establish new connections back to the
application on the LAN side using the Open Ports.
Applications such as games, video conferencing, and other remote
access applications require that specific ports in the Router's firewall be
opened for access by applications.
You can configure the port settings on this window by clicking the "Select
an application" radio button and then using the drop-down menu to
choose an existing application, or by clicking the "Custom
application" radio button and entering your own Application Rule in the
field provided. Click Apply Settings when you are finished with the port
setting configuration. The new Application Rule will appear in the Active
Application Rules table at the bottom of the window.
