1. A method of gateway optimization, comprising:
receiving, at a first gateway associated with a first tenant within a data center, a packet directed to a first public network address of an endpoint associated with a second tenant within the data center;
performing, by the first gateway, network address translation (NAT) to translate the first public network address to a private network address of the endpoint;
forwarding, by the first gateway, the packet to an edge gateway of the data center;
forwarding, by the edge gateway, the packet to a second gateway associated with the second tenant within the data center without sending the packet to a public interface of the edge gateway; and
forwarding, by the second gateway, the packet to the endpoint.
