  • Publication number: 20100122337
    Abstract: Systems and methods provide a secure network path through an inner and outer firewall pair between a mobile node on a foreign network and a corresponding node on a home network. One aspect of the systems and methods includes providing a mobile IP proxy between the mobile node and a VPN gateway inside the firewalls. The mobile IP proxy acts as a surrogate home agent to the mobile node, and acts as a surrogate mobile node to a home agent residing on the home network.

  • Patent number: 7580396
    Abstract: A method, apparatus and system which enable a mobile node to request dynamic allocation of a home address and to maintain that home address when roaming between a home subnet and a foreign subnet. According to one embodiment, the mobile node may acquire a home address from its home agent by using a Network Access Identifier (“NAI”) extension in a registration request. The mobile node may send out this registration request when it first starts up, regardless of whether it is on its home subnet or a foreign subnet. Additionally, the mobile node may set a bit in the registration request to inform the home agent that it is on its home network. If the bit is not set, the home agent may deduce that the mobile node is on a foreign network. In either instance, the mobile node may continue to use its originally acquired home address.

  • Patent number: 7428226
    Abstract: A method, apparatus and system provide a seamless, secure roaming solution. Embodiments of the present invention enable secure transmission of IP packets across enterprise security gateways. According to one embodiment, a mobile node on an external network may register with an external home agent using an external home address. The mobile node may also establish a secure path to the security gateway using the external home address and an internal home address. The mobile node may thereafter use the secure path to correspond with nodes on the external network. In other embodiments, the mobile node may use this secure path to register with an internal home agent on a home network, using the internal home address. The mobile node may then correspond with nodes on the home network via the secure path.
