My Company works with a few different VLans. I'm currently setting up a new PRTG Server, since our old one is almost 6 Years old. The new server can reach the different vlans via a Firewall Route. So in the firewall there is a Route from the PRTG to our Management VLan, so that it can Monitor our Switches. It is able to find the divces Via ping, but unable to establish a SNMP Connection. We use SNMPv3, the PRTG settings are all correct, i checked that 3 Times over. The Firewall Route allows for Ping aswell as SNMP. What could be a reason that the Sensors are still not working?
SNMP Sensors dont work/ can't be found
