Using the Configuration Menu
Advanced > Applications
Some applications require multiple connections, such as Internet gaming, video 
conferencing, and Internet telephony. These applications have difficulties working 
through NAT (Network Address Translation). 
Special Applications
makes some of these 
applications work with the DI-614+. 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 one from the drop down list and select an ID number you want to use. Then click 
the “Copy to” button and the router will fill in the appropriate information to the list. You 
will then need to enable the service. 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.
