Abstract

The present invention facilitates communications between a first network and a second network using an information routing device having an auto-configuration feature. The auto-configuration feature negotiates what authentication protocol will be used when the networks transfer information. Once the authentication protocol is negotiated by the device, the device intercepts and stores information transferred between networks. In this manner, the device can emulate a first network when coupled to a second network by providing the necessary stored information directly to the second network, and vice versa.

Claims

1. Apparatus for facilitating communications between previously connected first and second networks, the apparatus comprising:

a device having a microprocessor programmed to receive and transmit communications between the first and second networks; and

a programmed routine stored in memory for use with the microprocessor, the programmed routine configured to intercept and store information transferred between the first and second networks by negotiating use of an unencrypted authentication protocol,

wherein the device is configured to automatically intercept and store information from the second network either before or at the time that the second network requests access to the first network,

wherein the device further is configured to automatically intercept and store information from the second network by emulating the first network.

2. The apparatus of claim 1 wherein the device is further configured to automatically provide the first network with the stored information when the first network requests that information from the second network.

3. The apparatus of claim 1 wherein the device further is configured to automatically intercept and store information from the first network either before or at the time that the first network requests access to the second network.

4. The apparatus of claim 3 wherein the device is further configured to automatically provide the second network with the stored information when the second network requests that information from the first network.

5. The apparatus of claim 1 wherein the first network is an Internet service provider.

6. The apparatus of claim 5 wherein the second network is a local area network comprising at least one computer.

7. The apparatus of claim 1 wherein the programmed routine negotiates the use of password authentication protocol for communication between the device and the second network.

8. The apparatus of claim 1 wherein the programmed routine is adapted to negotiate from a more secure authentication protocol to a less secure authentication protocol.

9. The apparatus of claim 1 wherein the device is adapted to perform communications between the first and second networks using a cable modem.

10. The apparatus of claim 1 wherein the device is adapted to perform communications between the first and second networks using a digital subscriber line.

11. The apparatus of claim 1 wherein the device is adapted to perform communications between the first and second networks using a dial-up modem.

12. The apparatus of claim 1 wherein the device is adapted to perform wireless communications between the first and second networks.

13. The apparatus of claim 1 wherein the stored information comprises network identification or authentication information.

14. The apparatus of claim 13 wherein the stored information is a username and password.

23. The apparatus of claim 1 wherein the device is configured to automatically intercept and store information from the second network by negotiating with the second network when the second network is not accessing the first network.

24. The apparatus of claim 1 wherein the device is configured to automatically intercept and store information from the second network, without the need for a user to input information into the device.

25. The apparatus of claim 1 wherein the device is further configured to intercept and store information from the first network by emulating the second network,

wherein the first network is an Internet service provider.

26. The apparatus of claim 1 wherein the device is not pre-configured with network identification information or authentication information, and

wherein the device is configured to automatically intercept and store network identification information or authentication information from the second network.

27. The apparatus of claim 1 wherein the device further is configured to subsequently provide the first network with the stored information using the highest encryption level supported.

28. The apparatus of claim 1 wherein the device is configured to intercept and store information from the second network by falsely indicating that communications in an encrypted protocol cannot be supported so that an unencrypted authentication protocol is negotiated.

15. A method for facilitating communications between previously connected first and second networks, the method comprising:

providing a device having a microprocessor and at least one software algorithm stored in memory associated with the microprocessor;

using the software algorithm to negotiate an authentication protocol to be used to enable communications between the first and second networks; and

using the device to acquire information from the second network prior to or at the time that the second network requests access to the first network,

wherein using the device to acquire information from the second network comprises emulating the first network.

16. The method of claim 15 further comprising using the device to provide the first network with the stored information when the first network requests that information from the second network.

17. The method of claim 15 further comprising using the device to acquire information from the first network prior to or at the time that the first network requests access to the second network.

18. The method of claim 17 further comprising using the device to provide the second network with the stored information when the second network requests that information from the first network.

19. The method of claim 15 wherein the software algorithm negotiates from a more secure authentication protocol to a less secure authentication protocol.

20. The method of claim 15 wherein the software algorithm causes the device and the second network to communicate using password authentication protocol.

21. The method of claim 15 wherein the stored information comprises network identification or authentication information.

22. The method of claim 21 wherein the stored information is a username and password.

29. Apparatus for facilitating communications between first and second networks, the apparatus comprising:

a device having a microprocessor programmed to receive and transmit communications between the first and second networks; and

a programmed routine stored in memory for use with the microprocessor, the programmed routine configured to intercept and store information transferred between the first and second networks by negotiating use of an unencrypted authentication protocol,

wherein the device is not pre-configured with network identification information or authentication information,

wherein the device further is configured to automatically intercept and store network identification or authentication information from the second network either before or at the time that the second network requests access to the first network.

30. Apparatus for facilitating communications between first and second networks, the apparatus comprising:

a device having a microprocessor programmed to receive and transmit communications between the first and second networks; and

a programmed routine stored in memory for use with the microprocessor, the programmed routine configured to intercept and store information transferred between the first and second networks by negotiating use of an unencrypted authentication protocol,

wherein the device is configured to automatically intercept and store information from the second network either before or at the time that the second network requests access to the first network,

wherein the device further is configured to automatically intercept and store information from the first network either before or at the time that the first network requests access to the second network.
