7.15.2 Trigger Port Forwarding Example
The following is an example of trigger port forwarding. In this example, J is Jane ’ s
computer and S is the Real Audio server.
Figure 50 Trigger Port Forwarding Example
1 Jane requests a file from the Real Audio server (port 7070).
2 Port 7070 is a “ trigger ” port and causes the MAX208M2W Series to record Jane ’ s
computer IP address. The MAX208M2W Series 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.

The MAX208M2W Series forwards the traffic to Jane ’ s computer IP address.
