Hi all. I have been successfully remotely monitoring a Sophos XG Firewall via SNMP (using MRTG), mainly to monitor incoming and outgoing bandwidth on all 3 Ethernet ports. To clarify... there is an MRTG server out on the Internet, connecting to the Sophos via the Internet (WAN). There is a firewall rule that maps the non-standard port I am using on the WAN, to the standard UDP 161 on the LAN. SNMP is enabled in the Sophos, with a community string set, etc. This has worked for years.
Recently I upgraded firmware from "SFOS 17.5.15 MR-15" to "SFOS 18.5.3 MR-3-Build408" and this monitoring via SNMP broke. I was able to duplicate the problem by rolling back to "SFOS 17.5.15 MR-15" and SNMP started to work again. Again, I booted "SFOS 18.5.3 MR-3-Build408" and it stopped... reverted to SFOS 17.5.15 MR-15" and it started to work again... so left it there.
Has anyone else noticed this problem? I am not sure, as a 'free' user, if I am able to report the problem to Sophos directly or get any other type of help in identifying the cause?
Thanks!
