ABSTRACT:
A method and system for routing an externally generated message in a network includes receiving at an ingress port of a network a message from an external network. The message includes Internet protocol (IP) source and destination addresses and message data. The IP source and destination addresses are translated to internal addresses that are non-forwardable in the external network. The message data is routed in the network based on the internal addresses.
