Some applications require multiple connections, such as Internet gaming, video
conferencing, Internet telephony, and others. These applications have difficulties working
through NAT (Network Address Translation). Special Applications makes some of these
applications work with the DI-824VUP. If you need to run applications that require multiple
connections, specify the port normally associated with an application in the Trigger
field, then enter the public ports associated with the trigger port into the Incoming
Ports field.
At the bottom of the screen, there are already defined special applications. To use them,
select them from the list by clicking a check mark next to the application name. Users
may configure the special applications by clicking the Edit icon next to the application.
If the mechanism of Special Applications fails to make an application work, try using
DMZ host instead.
