ABSTRACT:
Methods and apparatus for enabling VPN based mobility are provided. A VPN client having a client subnetwork address corresponding to a particular subnetwork can create a VPN tunnel using an enterprise address from a VPN server. Using the VPN tunnel, the VPN client can establish sessions with a variety of destination nodes including destination nodes on a private or enterprise network associated with the VPN server. When the client moves, the VPN client can acquire a new address that may correspond to a new subnetwork, but the VPN server provides the VPN client with the same enterprise address. Accordingly, the VPN client can maintain existing sessions with destination nodes using the same enterprise address.
