∙Special Applications
Some applications, such as Internet gaming, videoconferencing, Internet telephony require multiple connections. These applications cannot work with Network Address Translation (NAT) 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 or port range normally associated with an application in the “Trigger Port” field, select the protocol type as TCP or UDP, and then enter the public ports and data type associated with the trigger port to open them for inbound traffic.
The maximum range that you can use for all NAT ports is 0 to 65535.
