Absolutely. We're trying to reduce our public IPv4 usage, so having one per tenant network (not even including floating IPs) is a drain.
Instead of having: instance -> (gateway IP) virtual router NAT (public IP) -> (public gateway) router We want to have: instance -> (gateway IP) virtual router NAT (private IP) -> (private gateway) router NAT We have lots of networks, so this would have a huge impact on our IP usage. Also, in this case, floating IP addresses would still work the same way that they do now.\ Thanks Assaf On Tue, Apr 14, 2015 at 6:06 PM, Assaf Muller <amul...@redhat.com> wrote: > ----- Original Message ----- > > Hi folks, > > > > Looking for a bit of advice on how to accomplish something with Neutron. > Our > > setup uses OVS+GRE with isolated tenant networks.
