ABSTRACT:
Methods and systems are provided for secure Mobile-IP traffic traversing network address translation (NAT). A virtual-private-network (VPN) tunnel extending between the mobile node and the home agent is established, wherein the home agent comprises a VPN function. Establishing the VPN tunnel comprises (i) the mobile node communicating with the home agent at a public address of the home agent via a private network, a NAT device, and a public network and (ii) the home agent assigning the mobile node a first public address. The mobile node is registered with the home agent. Registering the mobile node comprises (i) the mobile node communicating via the VPN tunnel with the home agent at the public address of the home agent and (ii) establishing the first public address as a home address for the mobile node for, for example, purposes of Mobile-IP communication.
