94CHAPTER 5: CONFIGURING THE ROUTER

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:

1Specify 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.

2Specify 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.
