Abstract
Disclosed embodiments describe systems and methods for tunneling packets. A tunnel between a first intermediary device and a second intermediary device is established that encapsulates payload packets of transport layer connections between a client and a server. The first intermediary device identifies, from a first packet of a transport layer connection between the client and the server, packet header information. The first intermediary device populates a destination port and a source port of a header of a second packet to be transmitted via the tunnel. The destination port is populated with a predetermined destination port, and the source port includes a first hash of a tuple of the packet header information of the first packet. The second packet includes the first packet as a payload, and is load balanced across paths to the second intermediary device based on a second hash of the header of the second packet.
