Trigger Ports forwards a range of ports to an IP address on the LAN only after specific out-

• Global Port Range: Range of ports on which incoming traffic will be received.
• Local Trigger Port: Port number of the type of outbound traffic that needs to happen
(will be the trigger) to then allow the configured ports for inbound traffic.
