94 C HAPTER 5: C ONFIGURING THE R OUTER
Special Applications Special Applications (port triggering) let you choose specific ports to be
open for specific applications to work properly with the Network Address
Translation (NAT) feature of the Router.
Figure 71 Special Applications Screen
A list of popular applications has been included to choose from. Select
the application from the Popular Applications drop-down menu. Then
select the row that you want to copy the settings to from the Copy To
drop-down menu, and click Copy To. The settings will be transferred to
the row that you specified. Click Apply to save the setting for that
application.
If your application is not listed, you will need to check with the
application vendor to determine which ports need to be configured. You
can manually enter the port information into the Router. To manually
enter the port information:
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.
2 Specify the Public Ports used by the application, 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. Note that the range of the
trigger port is from 1 to 65535. You can enter the port number as one
single port, or in range, use comma to separate different entries.
3 Check the Enabled checkbox, then click Apply.
