A first network configured to connect a terminal to a home network during a time that the terminal is roaming within the first network. The first network includes a plurality of attachment points, wherein a first attachment point is configured to receive an attach request from the terminal, and wherein the attach request includes a request from the terminal for an IP address from an anchoring point within the home network. The first network further includes an Authentication/Authorization/Accounting server proxy configured to determine whether the terminal is authorized to attach to the first attachment point, wherein in response to the terminal being authorized to attach to the first attachment point, i) a first tunnel is created between the first attachment point and a second attachment point, and ii) a second tunnel is created between the second attachment point and the anchoring point within the home network.
