Hi Guru, Let me try with the following use cases. 1. No floating IP is used for east-west routing traffic. E.g. VM1 <-> VM2: Private IPs are used. No NAT applied.
2. Floating IP is used for south-north default route to internet traffic. E.g. VM originated internet traffic: SNAT is applied to change source IP to floating IP. UNSNAT is applied to change destination IP back to private IP. Thanks.

Specifically: 1. If the destination IP is part of some private layer3 domain, the usual private IP is used to to reach the destination in the private layer3 domain. 2. If the destination IP is not part of the private layer3 domain but part of the public layer3 domain, the public IP (I.e. Floating IP) is used to replace the private IP address of the source packet. I don't understand what you mean above. Please re-phrase with the direction of the packet. Does OVN support this behavior today? Thanks.
