With port triggering, we define two kinds of ports: Trigger Port and Target Port. Trigger
port is the service request with a specific destination port number sent from a LAN side
host. Target Port is the port this specific application requires a LAN host to listen to. Thus,
the server returns responses to these ports.
For example:
1.
John requests a file from the Real Audio server (port 7070).
Port 7070 is a “trigger”
port and causes the device to record John’s computer IP address. The DVW3201B
associates John's computer IP address with the “target” port range of 6970-7170.
2. The Real Audio server responds to a port number ranging between 6970-7170.
3. The DVW3201B forwards the traffic to John’s computer IP address.
4. Only John can connect to the Real Audio server until the connection is closed or times
out.
