23.5 Trigger Port Setup
The ZyAIR records the IP address of a LAN computer that requests a service that you have defined as a
“trigger port”. The response from the Internet can then be forwarded directly to the LAN computer. Trigger
ports are transient; they only exist while in use or are timed out. The following is a trigger port example.
