A manner of extending a home network to a mobile device. A proxy server receives a request from a signaling gateway to transfer a communication session established between a home agent and a foreign agent. This may be done, for example, to accommodate an anticipated high-bandwidth transaction. If the proxy server has adequate resources available, it can accept the session. The agents provided with the address of the proxy server and independently send connection requests. The proxy server ensures that both agents are authenticated, and establishes secure communication tunnels. Traffic is then forwarded between the tunnels, in some cases after manipulation within the proxy server. Status messages may be multicast to inform signaling gateways or other entities of the resources available at the proxy server for this purpose.
