A nomadic
router or translator enables a
laptop computer or other portable terminal which is configured to be connected to a home network to be connected to any location on
the internet or other
digital data communication
system. The
router automatically and transparently re-configures the terminal to its new location and processes outgoing and incoming data. The
router includes a processor which appears as the home network to the terminal, and appears as the terminal to the communication
system. The terminal has a permanent address, the router has a router or translator address, and the terminal transmits outgoing data to the
system including the permanent address as a
source address. The processor translates the outgoing data by replacing the permanent address with the router address as the
source address. The terminal receives incoming data from the system including the router address as a destination address, and the processor translates the incoming data by replacing the router address with the permanent address as the destination address. Alternatively, the terminal can be directly connected to a point on a local network, and the router connected to another point on the network. The router can be employed to implement numerous applications including nomadic e-mail, network file
synchronizer,
database synchronizer, instant network, nomadic internet and trade show router and can also be utilized as a fixed nomadic router.
