Abstract
Methods, systems and computer program products are provided which route messages from a source device on a first network to a destination device on a second network through a first routing device where the first routing device transmits a message to a master routing device. The first routing device receives a routing address from the master routing device responsive to the transmitted message. The routing address specifies an address of a device to which subsequent communications to the destination device are routed. The first routing device stores the received routing address in a list of addresses so as to associate the stored routing address with an address of the destination device of the message. The first routing device may also determine a routing address for a second message from the stored list of routing addresses based upon a destination address of the second message and transmit the second message to the determined routing address. The routing table of the routing device may be updated without requiring modification of TCP/IP messages.
