Below are links to diagrams illustrating the current state of north-south flows when using DVR [1], and the desired state [2]. Keep in mind both diagrams are considering the scenario where fixed IP's are routable by the operator and some sort of routing mechanism is in place to direct incoming traffic to the appropriate next-hop for the VM. This could be static routes or BGP, it doesn't matter. Simply assume something is in place to communicate next-hops to the upstream router. No SNAT needs to occur, and to simplify the discussion let's assume floating IP's are not being used. Using floating IP's in this scenario doesn't change the data flow in the desired state [2].
