Currently in Neutron, If an instance has a floating IP, then that will be used for both inbound and outbound traffic. If an instance does not have a floating IP, it can make connections out using the gateway IP (SNAT using PAT/NAT Overload). Does the idea in this blueprint is to implement PAT on both directions using only the gateway IP? Also, did you see this one [1]? <br></div><div><br></div><div>Thanks,<br></div><div>Nir<br></div><div><br></div><div>[1] https://blueprints.launchpad.net/neutron/+spec/router-port-forwarding<br></div></div></body></html>
