Methods are provided for communicating between devices in a network and remote servers, which may be located behind intermediate devices such as load balancers, by encapsulating messages sent by those devices and, in one implementation, to a load balancer in a transport header that may be understood by that load balancer; decapsulating the message from the transport header; re-encapuslating the message in a GRE tunnel and passing the message to a server, where the GRE tunnel is removed. Methods are also provided for communicating between devices in a network and local gateways by encapsulating messages sent by those devices and, in one implementation, to a load balancer in a transport header that may be understood by that gateway, and decapsulating the message from the transport header at the gateway.
