Hi all, I'm also interested in this setup.

Can you please be a bit more specific on the issues and bug reports? I
did some testing on this kind of setup, and as far as I understand
Neutron in Juno does not allow you to change the policy for one
specific network, so the best I could do is to allow *any* tenant to
plug a port on *any* external network, while in my setup I would like
to only allow tenants to plug an interface on one specific external
network (I will create different "external" networks of this kind)
I wrote a short blogpost with the configuration I made:

I really like this design too, very KISS-y
