I'm attempting to monitor a Barracuda firewall however when I create a new SNMP library sensor against the Barracuda object in PRTG, the "Preparing sensor settings" progress bar shows for a couple of minutes then errors with:
|"No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (SNMP error # -2003)"|
I have completed the following steps:
- Set up access on Barracuda to allow SNMP from my PRTG host on port 161
- Tested connectivity from PRTG server to Barracuda using Paessler SNMP tester
- Imported the Barracuda SNMP MIB and converted to a .oidlib on PRTG server
I have also created a partial .oidlib with two ID's and it still fails, although I can the query device successfully using these ID's from the tester.
The firewall logs show the requests being accepted from PRTG but they timeout based on the UDP timeout on the firewall. Increasing the UDP timeout does not help so I am at a loss as to what the issue is here?
