Description

If you enter a LAN IP into the Setup Wizard such as x.x.x.0/24 or x.x.x.255/24, the setup wizard does not complain and will continue with the (invalid) IP setup. The setup wizard should reject the input if the user enters the subnet ID or broadcast IP of a subnet.

Currently it does reject if it's obviously wrong, e.g. x.x.x.300, via JavaScript, but it misses the above case.

The only potential exception would be if the CIDR were 31 or 32, if we choose to support those in the wizard, in which case it may be a valid configuration.
