Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony, VPNs, and others. These applications have difficulties working through NAT (Network Address Translation). 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 (Transmission Control Protocol, UDP (User Datagram Protocol), or both, then enter the public ports associated with the trigger port to open them for inbound traffic.
