Using the Configuration Menu
Advanced > Application
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.
Note!
Only one PC can use each Special Application tunnel.
Trigger Port
This is the port used to trigger the application. It can be
either a single port or a range of ports.
Public Ports
This is the port number on the WAN side that will be used to
access the application. You may define a single port or a range
of ports. You can use a comma to add multiple ports or port
ranges.
