Abstract
A method of payload editing in an intelligent transparent gateway is provided. Certain applications include addressing information within the data streams of their sessions. When running on clients that are sharing a connection, such applications would send private, unreachable addressing information to remote peers, and the latter would be unable to respond to the clients's requests. The system of the instant invention supports an extensible means of modifying a session's application-layer data in flight, beyond the modifications made to the session's network-layer and transport-layer addressing information. Extensibility is achieved by allowing drivers to inspect the application-layer data in each packet received for a session, and to edit the application data in each packet. These editors register themselves with the gNAT of the instant invention as handlers for a specific TCP/UDP port number, and are henceforth invoked for each message translated in matching sessions.
