Comment 6 for bug 1905295

I think a neutron router won't do NAT if the internal and external addresses are of the same scope, right? And for IPv6 there is no NAT :)

As far as the RFE goes, my first thought is this would be implemented as a single external interface of the router with >1 default route? But it looks like above you're talking about a second external interface since there is an additional network and subnet. As Liu mentioned, this does complicate things, especially from an IP address consumption viewpoint, I just haven't wrapped my head around it yet.
