A method involving receiving, at a network device, a first layer 2 network packet from a client, the first layer 2 network packet encapsulating a layer 3 network packet; forwarding the first layer 2 network packet to a server by associating the layer 3 destination host with a particular server connected to the network device, creating a modified first layer 2 network packet by overwriting the layer 2 destination address of the first layer 2 network packet with the layer 2 network address of the server, and sending the modified first layer 2 network packet over a network; receiving, at the network device, a second layer 2 network packet from the server; and forwarding the second layer 2 network packet to the client by creating a modified second layer 2 network packet by overwriting the layer 2 source address of the second layer 2 network packet with the layer 2 network address of the network device and sending the modified second layer 2 network packet over a network.
