How to Reset Watchguard Firebox Edge to Factory Default

To set the Firebox X Edge e-Series to the factory default settings:

Disconnect the power supply.
Hold down the Reset button on the rear side of the Edge.
Connect the power supply while you continue to hold down the Reset button.
Continue to hold down the button until the yellow Attn light stays on. This shows you that the Edge was successfully restored to the factory default settings.
This process can take 45 seconds or more.
Do not try to connect to the Edge at this time. You must start the Edge one more time, as the subsequent steps show. If you do not start the Edge one more time, when you try to connect to the Edge you will see a web page that shows the message, “Your WatchGuard Firebox X Edge is running from a backup copy of firmware.” You could also see this message if the Reset button is stuck in the depressed position. If you continue to see this page, check the Reset button, and start the Edge again.

Disconnect the power supply.
Connect the power supply again.
The Power Indicator is on and your Edge is reset.

Once it's reset, you can use 192.168.111.1 to access the firebox.
