Hi,
We had the same Thing happen to us 3x in the last 2 weeks. We have 2 ASG220 running UTM9 Firmware, in a Active/Standby HA configuration. At some stage, the active UTM just stopped handling any traffic.
Traffic over IPSec VPNs wasn't routed anymore, the Internet was not accessible, all REDs were disconnected. Still the UTM could be reached through ist web Interface. As soon as we disconnected the active UTM, the standby one took over and everything was fixed in a matter of seconds.
This has happened to both nodes. I was hoping that it was a Hardware matter that just affected one UTM, but both of them have shown this behaviour at least one. So I guess it's not a HW defect.
Also we have not done anything to the Firmware for at least 2 months before the first case happened. Then we updated the Firmware to the newest one (9.135-2), and had the issue appear again twice.
Do you have any idea what this could be, or where we could look for the root of the Problem?
Thanks, Chris
