I have a Firewall WatchGuard X1000, and it gets regularly hanged. I tried to solve this upgrading the firmware, downgrading, but we still have the same problem.
We replace it for another x1000 Firewall (we have it before on "high availavility mode"), and this gets hanged too. :S
Do you know the same behavior and how to fix it?.
We find a lot of cases on the net, but no solutions.
