Having trouble with this. Was following this article to monitor our firewall, but I am unable to do so. https://kb.paessler.com/en/topic/73179-how-can-i-monitor-sophos-utm-devices-with-prtg
Our firewall management/LAN is accessed by IP + Custom Port. When trying to use SNMP Traffic sensor and just straight IP, no port , I get the error:
----- Could not create the SNMP Traffic sensor on device Sophos Firewall (IPHERE).
The sensor does not get a response from the device you want to monitor. The reason might be that the SNMP credentials are wrong or that the device does not support the required uptime OID (126.96.36.199.188.8.131.52.0) for traffic sensors. To resolve this issue, check the SNMP access rights of the device or contact the device vendor. (code: PE244) -----
When using IP AND custom port, I get:
Could not create the SNMP Traffic sensor on device Sophos Firewall (IPHERE:PORT). Socket Error # 11001 Host not found.
What gives? I've enabled SNMP on my firewall V2C as well as on the LAN port, I've allowed access from my PRTG server, etc.
Anyone have some advice?
