A gateway, configured for providing connectivity between a wide area network and mobile routers within a mobile ad hoc network, is configured for registering the mobile routers with their respective home agents using a prescribed mobile IP protocol. The gateway identifies the mobile routers using a prescribed proactive mobile ad hoc network routing protocol. The gateway locates, for each identified mobile router, its corresponding home agent via the wide area network according to the prescribed mobile IP protocol, and registers the corresponding identified mobile router with the home agent according to the prescribed mobile IP protocol. The gateway can then forward a packet received from a home agent to the corresponding mobile router. Hence, the gateway provides mobile routers within a mobile ad hoc network with access to the wide area network, without any necessity for the prescribed mobile IP protocol to be implemented within the mobile routers.
