A system enables the selective connection of a data terminal (2) to one of a plurality of VPNs (20-24) formed within a public telecommunication network. A data storage computer (7) within the system stores users identity information indicative of the identity of authorized users to one or more of said VPNs, and VPN authorisation information indicative of those VPNs that each authorised user is authorised to use. Retrieval means, such as a web server (4), send a user identifier indicative of a selected authorised user to the data storage computer and retrieve a list of VPNs accessible by the selected authorised user from the first data storage computer. The data terminal includes a display for presenting the list of VPNs, and selection means for accepting the selection at the data terminal of one of the virtual private networks. The system includes authenticating means, such as a RADIUS client/server, for authenticating the identity of said selected authorised user, the data terminal being connected to the selected VPN if the authentication is successful. |
