There is a function of Monitor Port provided by Vigor2130/Vigor2750 which can lead and direct the packets passing through LAN and WAN ports to specified LAN port. Meanwhile, it can offer full information to Draytek Support staff for problem analysis in troubleshooting.

 

I. Terms Explanation

Monitor Port: The function of such port is “monitoring”. Only the selected port is specified for monitoring; other ports are treated as monitored ports.Monitor ingress port: Monitor the packets received.

Monitor egress port: Monitor the packets transmitted.

 

* Loop (or round robin) might occur while monitoring WAN port. Please pay attention to the line connection.

 

II. Example

 

From the above figure, LAN1 is configured to monitor the packets received in WAN port and packets received/transmitted via LAN2 port. Therefore, the host connecting to LAN1 can receive the packets passing through LAN1, LAN2 and WAN ports by using the capturing packets software, e.g., Wireshark, OmniPeer and so on. Refer to the following figure:

 

If the host does not monitor packets passing through WAN port, only the packets transmitted from LAN1 and LAN2 will be seen. Refer to the following figure:
