Специальные приложения
Some applications require multiple connections, such as Internet gaming, video conferencing, Internet
telephony and others. These applications cannot work when Network Address Translation (NAT) is enabled. If
you need to run applications that require multiple connections, 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.
