4.4.4 Advanced > Port Triggering
Port triggering is a way to automate port forwarding: outbound traffic on predefined ports
('triggering ports') causes inbound traffic to specific incoming ports to be dynamically
forwarded to the initiating host, while the outbound ports are in use. This allows computers
behind a NAT-enabled router on a local network to provide services that would normally
require the computer to have a fixed address on the local network. Port triggering can open an
incoming port when a client on the local network makes an outgoing connection on a
predetermined port or range of ports. In the Port Trigger page you can specify up to 15 rules
with parameters for Port Triggering. The following configuration parameters are available:
