I have a Watchguard Firebox II that one of the Junior IT guys here played with and rendered it usless.
Long and the short of it is the trusted interface is no longer responding.
I have been told to put a X-over cable between the External port and the Optional port and that should put it in configuration mode.
When I do that and run the quick set up wizard, it looks like it is going to work, but then I get an error that reads "Connect() failed"
Can anyone point me in a direction here please?
