Hi, for some reason it is possible to do this:

nova network-create --fixed-range-v4 10.0.101.0/24 --gateway 10.0.100.1 --dns1 8.8.8.8 --project-id 2575481bef7f4fde956202e3070fe688 net1

You can see I specified a gateway that is not from that fixed-range. Why is that possible at all? For me it creates errors on the nova-network host when I by mistake specify the same gateway address twice.
