Prestige 324 User's Guide 1. Jane requests a file from the Real Audio server (port 7070). 2. Port 7070 is a "trigger" port and causes the Prestige to record Jane's computer IP address. The Prestige 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 Prestige 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 Prestige times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol). 7.6.2 Two Points To Remember About Trigger Ports 1. Trigger events only happen on data that is going coming from inside the Prestige and going to the outside. 2.
