Jane requests a file from the Real Audio server (port 7070).
2
Port 7070 is a “trigger” port and causes the Zyxel Device to record Jane’s computer IP address. The Zyxel
Device associates Jane's computer IP address with the "open" port range of 6970-7170.
3
The Real Audio server responds using a port number ranging between 6970-7170.
4
The Zyxel Device forwards the traffic to Jane’s computer IP address.Only Jane can connect to the Real
Audio server until the connection is closed or times out. The Zyxel Device times out in three minutes with
UDP (User Datagram Protocol) or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol).
