Abstract

Data is received by a service provider that is indicative of a selected server-side system and a selected client-side system between which a VPN is to be established. Security settings are then automatically determined for the client-side system based at least partially on the data. The security settings are preferably public and private keys and/or a Digital Certificate. VPN configuration details, including the security settings, are then automatically transmitted to the client-side system. The client side system then uses the configuration details to automatically configure itself to establish a secure VPN tunnel between the server-side system and itself. VPN configuration details may also be automatically transmitted to a VPN concentrator within the server-side system. A Virtual Private Network tunnel is subsequently established between the client-side system and the server-side system, and the tunnel'"'"'s operation verified. A computer program product for configuring a VPN system is also provided.

Claims

1. A computer implemented method for remotely configuring a Virtual Private Network (VPN) between a client-side system and a server-side system, comprising:

receiving data at a service provider system indicative of a selected server-side system and a selected client-side system between which a VPN is to be established;

automatically determining security settings at the service provider system for said client-side system based at least partially on said data; and

automatically transmitting VPN configuration details from the service provider system to a modem of said client-side system, where said VPN configuration details include said security settings,

such that in use said modem of said client-side system is automatically configured with said VPN configuration details to establish a secure VPN tunnel between said client-side system and said server-side system.

2. The computer implemented method of claim 1, wherein said receiving comprises obtaining said data indicative of a selected server in said server-side system and a selected user of said client-side system from a system administrator, via an electronic network.

3. The computer implemented method of claim 1, wherein said determining comprises creating a public and private key.

4. The computer implemented method of claim 1, wherein said determining comprises establishing a Digital Certificate.

5. The computer imnplementcd method of claim 1, further comprising:

automatically ascertaining further security settings for said server-side system;

automatically transmitting VPN configuration details to a concentrator within said server-side system, where said VPN configuration details include said further security settings.

6. The computer implemented method of claim 1, further comprising:

automatically ascertaining further security settings for said server-side system; and

automatically transmitting VPN configuration details to a firewall within said server-side system, where said VPN configuration details include said further security settings.

7. The computer implemented method of claim 1, wherein said transmitting comprises communicating said VPN configuration details to said modem within said client-side system.

8. The computer implemented method of claim 1, wherein said transmitting comprises communicating said VPN configuration details to a firewall on said modem within said client-side system.

9. The computer implemented method of claim 1, further comprising the step, after said determining step, of:

storing said data indicative of a selected server-side system and a selected client-side system between which a VPN is to be established and said security settings.

10. The computer implemented method of claim 1, further comprising the steps, after said automatically transmitting step, of:

receiving a password from said client-side system; and

authenticating said password.

11. The computer implemented method of claim 1, further comprising:

establishing a Virtual Private Network tunnel between said client-side system and said server-side system; and

verifying that said tunnel is operational.

12. The computer implemented method of claim 1, further comprising configuring a login page on said modem within said client-side system.

13. A computer program product for use in conjunction with a computer system for remotely configuring a Virtual Private Netwotic (VPN) between a client-side system and a server-side system, the computer program product comprising a computer readable storage and a computer program stored therein, the computer program comprising:

instructions for receiving data at a service provider system indicative of a selected server-side system and a selected client-side system between which a VPN is to be established;

instructions for automatically determining security settings for a modem of said client-side system based at least partially on said data; and

instructions for automatically transmitting VPN configuration details from said service provider system to said modem of said client-side system, where said VPN configuration details include said security settings, such that in use said modem of said client-side system is automatically configured with said VPN configuration details.

14. The computer program product of claim 13, wherein said instructions for receiving further comprise instructions for obtaining said data indicative of a selected server in said server-side system and a selected user of said client-side system from a system administrator, via an electronic network.

15. The computer program product of claim 13, wherein said instructions for determining further comprise instructions for creating a public and private key.

16. The computer program product of claim 13, wherein said instructions for determining further comprise instructions for establishing a Digital Certificate.

17. The computer program product of claim 13, wherein said computer program further comprises:

instructions for automatically ascertaining further security settings for said server-side system; and

instructions for automatically transmitting VPN configuration details to a concentrator within said server-side system, where said VPN configuration details include said further security settings.

18. A computer implemented method for remotely configuring a Virtual Private Network (VPN) between a client-side system and a server-side system, comprising:

receiving at a modem within said client-side system, VPN configuration details from a service provider system, where said VPN configuration details include security settings for establishing a VPN with a remote server-side system; and

automatically configuring said modem, with said VPN configuration details,

such that in use a secure VPN tunnel can be established between said client-side system and said server-side system.

19. The computer implemented method of claim 18, wherein said configuring further comprises setting-up a firewall on said modem with said modem with said security settings.

20. The computer implemented method of claim 18, further comprising:

receiving a password from said client-side system; and

authenticating said password.
