OK it does work..
Could it be made a bit clearer that if you set up a scope that is not directly connected to the box, that you will need to use a dhcp relay.
Rather than the
“WARNING: DHCP Server is not active on this subnet because there is not a network interface with an IP on the subnet”
this makes it look like the scope is not active at all.
