Embodiment Construction

[0050]Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0051]FIG. 2 is a block diagram illustrating a communication system with two gateway nodes in one embodiment of the invention.

[0052]In FIG. 2 there is a client node 250. It communicates with an IP access network 252. The IP access network may be any wired or wireless network. In FIG. 2 there is also a Virtual Private Network gateway VPN-GW 268. VPN-GW 268 provides IP Security (IP-SEC) security associations for client nodes such as client node 250. The security associations are provided over IP access net-work 252. In FIG. 2 there are two authentication authorization and accounting servers, namely AAAv 262 and AAAh 264. AAAv 262 acts as the AAA server within the network of VPN-GW 268, whereas AAAh 264 acts as the AAA server within the home network of the mobile subscriber associated with client node 250. VPN-GW 268 communicates with AAAv

Abstract

The invention relates to a method, which comprising initiating the establishment of a security association between a client node and a gateway node. User data is obtained from an authentication server and the user is au-thenticated. Authorization is obtained for the user for certain network services from a separate authorization node. An authorized address is provided to the client node. The authorization is checked by the gateway node for the allowing outbound packets to specific destinations.
