Relatively new to PRTG v9, and have been tasked with how to solve a monitoring problem with a VPN using SNMP v1. We would like to see traffic patterns for bandwidth, speed, and latency specific to a VPN tunnel for our e-commerce (from here to Amazon) that is also running across our core production internet connection. I’m being told it’s not possible to discriminate the VPN from the production internet because of the firewall and inherent vpn encryption in the tunnel. I have read some knowledgebase threads here, that sounded like using a prtg remote probe w/packet sniffer sensor if configured at a router or switch monitoring port supplying the VPN connections to our core, perhaps just before the firewall in order to discriminate it from general traffic? I also read something where I would need to identify the OID to determine which VPN to do so, and something about reboots renaming the OID, so you would lose the monitoring on that tunnel?!? Still learning, so any suggestions or help appreciated.
