One thing that Watchguard did well in there new software version was to include the option to enable DHCP as part of the quick setup wizard. Here is why this is great. Previously you would start up your watchguard in safe mode and hook your computer to it. You would then get an IP address from it (10.0.0.2) which you could use to start your quick setup wizard. You would then configure the internal interface with the IP you would actually want and the reboot the watchguard. However previously DHCP was always off meaning you would then have to go and manually configure an IP address on your machine to match what you configured the internal interface as if you wanted to continue. Needless to say this was a pain in the butt.
