I have a sonic wall pro 200 installed between a small LAN and the internet router. The device is currently running version 126.96.36.199 of the firmware. I have upgraded the firmware to version 188.8.131.52 two separate times. Each time, however, I have had to roll it back to 184.108.40.206, as the upgrade appears to "lock-up" the sonic wall, preventing any users from getting out to the internet. Immediately following an upgrade, I'm able to examine the parameters of the sonic wall and they've all been rpreserved as they were before the upgrade. The SW will soon lock-up, however.
Has anyone had any experience with this?
