LAN can use the service in the same manner. This way you do not need to configure a new IP
address each time you want a different LAN computer to use the application.
For example:
Figure 64 Trigger Port Forwarding Process: Example
Jane requests a file from the Real Audio server (port 7070).
1
Port 7070 is a "trigger" port and causes the ZyXEL Device to record Jane's computer IP address.
2
The ZyXEL Device associates Jane's computer IP address with the "open" port range of 6970-7170.
The Real Audio server responds using a port number ranging between 6970-7170.
3
The ZyXEL Device forwards the traffic to Jane's computer IP address.
4
Only Jane can connect to the Real Audio server until the connection is closed or times out. The
5
ZyXEL Device times out in three minutes with UDP (User Datagram Protocol) or two hours with
TCP/IP (Transfer Control Protocol/Internet Protocol).
