Hi All, we have a Dell managed switch sending sFlow data to PRTG for bandwidth monitoring. I'm trying to monitor bandwidth usage for site-to-site VPN(s) that are set up as L2TP/IPSec connections. The sensor is set up to gather all ingress and egress traffic on the VPN endpoint IP, but nothing is showing up. A white paper on sFlow.org states that sFlow "supports" all L2-L7 traffic flows, so I'm guessing my PRTG sensor needs to be configured in a special way (??).
Is monitoring L2TP traffic via sFlow possible in PRTG and how do I set it up correctly?
Thx in advance for help and/or pointers! Rgds - Marcus.
