In an embodiment, a method is provided for communicating a protocol request at a network zone. In this method, the protocol request is received from a computing device and this protocol request is encapsulated in a different protocol. The protocol request is then transmitted to a different network zone by way of the different protocol. A message is then accessed from the different network zone by way of the different protocol, and this message includes a protocol response to the protocol request. The protocol response is extracted from the message and transmitted to the computing device.
