Juno Horizon has made it mandatory to have:
1. Public VN with external flag.
2. Set it as the external g/w of a Router
3. Subnets to be attached to Router by having router interfaces from those subnets.
4. Ports from subnets matching #2,#3, are the only ones that can be assigned a Floating IP
This is as per Neutron spec, which we weren't following all this while.
