I wanted to see if anyone else is running into the same issue I have been experiencing. One of my three UTM 120's (the most utilized one) has gone through two instances in the last week where it stops forwarding traffic on the internal eth0 interface. My outside monitoring shows that that the external interface stays up and our Site-to-Site VPN tunnels remain established. Since this has occurred right in the middle of our core business hours I haven't had the luxury to poke around determine a fix or cause and just had to go straight to the nuclear reboot option.
We have premium support so Sophos reps have accessed the device and checked the logs but haven't really come up with anything. The first instance occurred the day 9.206 was released so at the time we were still on 9.205 and the recommended action was to upgrade. The second occurrence of this issue was a few days after upgrading to 9.206.
I am curious if anyone else here has been running into a similar issue, if so have you found either a temporary or permanent fix for the problem.
