If the line is connected via the WAN port on the system's control unit, System Monitor should be configured to monitor the IP address of the system.
-
If the line is connected via a WAN port on a WAN3 module, System Monitor should be configured to monitor the IP address of the WAN3 unit.
If the leased line problem is to a specific destination, then System Monitor can record information pertinent to that connection only. By entering the appropriate service name in the PPP trace option settings Interface Name field. A blank entry means all the data connections (Services) are monitored.
Check for any PAP/CHAP password failure. This indicates that the Service configuration is not correct.
Note that the WAN Tx and WAN Rx information is in raw hex format only. An in-depth knowledge of the IP Packet make-up is required to manually decode these messages which is not done automatically.
