Question : How to access a Watchguard Firebox X750e Core

Hopefully a very simple question. A client gave me both of their Watchguard X750e Core boxes to reconfigure for a new setup.

Unfortunately, I have not been able to gain access to the boxes. Their internal IP addresses are pinging properly but I cannot access them through that IP address in a browser. (http://192.168.1.1)

Does anyone know if there is some proprietary software way to access these boxes, or maybe I need to add a port # to the URL?

Id prefer NOT to use the console connection.

You must download system manager in order to access the firebox without using the CLI.  The firebox does not have a web interface.  The client can be obtained from Watchguard's website, but I think you have to have a login.
