Connection Dropping | Watchguard Firebox x550e

[Hickmeister]

I just got a Watchguard Firebox x550e and successfully got 2.3.2-RELEASE installed.

But at random times all connections will just drop out and I cant access the web UI
Plus all this:

• Internet connection drops
• Can't ping router from external network
• Can't ping router from internal network
• Serial console using putty works fine and the 2 interfaces still have their ip's

Restarting fixes the issue until it happens again.

My WAN is a PPPoE connection.

Any info would be great!
