Port Triggering
Port triggering is a way to automate port forwarding with outbound traffic on predetermined ports
(‘triggering ports’), incoming ports are dynamically forwarded to the initiating host, while the
outbound ports are in use. Port triggering triggers can open an incoming port when a client on the
local network makes an outgoing connection on a predetermined port or a range of ports.
