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.
