Configuring the CheetahAccess Internet Gateway

Enabling Special Applications
Some applications, such as Internet gaming, videoconferencing, Internet telephony
and others, require multiple connections. These applications may not work when
Network Address Translation (NAT) is enabled. If you need to run applications that
require multiple connections, use the following screen to specify the additional public
ports to be opened for each application.
Specify the port normally associated with an application in the “Trigger Port” field,
select the protocol type as TCP or UDP, then enter the public ports associated with
the trigger port to open them for inbound traffic.
Note: If an application still cannot function correctly after enabling multiple ports via
the Special Application screen, you may have to open the client PC for full
Internet access using the DMZ Host option.
