To set up one of the listed Special Applications on your Router, do the
following:
1 Select Firewall from the main menu, then select Special Applications from
the sub-menu. The Special Applications screen displays
Figure 34 Special Application Screen
2 Select an application from the Popular Applications drop-down list.
3 Select the row that you want to copy the settings to from the Copy To
drop-down list, and click on Copy To. The settings will be transferred to
the row you specified.
4 Click Apply to save the setting for that application.
If the application you want to configure is not listed, you will need to
check with the application vendor to determine which ports need to be
configured. You can then manually input this port information into the
Router. To do this:
1 Specify the trigger port (the one used by the application when it is
initialized) in the Trigger Port column, and specify whether the trigger is
TCP or UDP in the Trigger Type column.
2 Specify the public ports used by the application in the Public Port column.
These are the ports that will need to be opened up in the firewall for the
application to work properly, . Also specify whether these ports are TCP
or UDP in the Public Type column.
3 If required, temporarily enable or disable an entry in the table by checking
or unchecking the Enabled checkbox.
