2. Port 7070 is a "trigger" port and causes the ZyAIR to record Jane's computer IP address. The ZyAIR
associates Jane's computer IP address with the "incoming" port range of 6970-7170.
3. The Real Audio server responds using a port number ranging between 6970-7170.
4. The ZyAIR forwards the traffic to Jane's computer IP address.
5. Only Jane can connect to the Real Audio server until the connection is closed or times out. The
ZyAIR times out in three minutes with UDP (User Datagram Protocol) or two hours with TCP/IP
(Transfer Control Protocol/Internet Protocol).
Two Points To Remember About Trigger Ports
1. Trigger events only happen on outgoing data (from the ZyAIR to the WAN).
2. Only one LAN computer can use a trigger port (range) at a time.
