Method and system for a point to point protocol-bridge operating mode in network communication system
First Claim
1. A system for providing a PPP-Bridge mode for a data network, comprising:
- a remote PPP server operatively coupled to a data network;
an access device operatively coupled to the remote server and configured to receive a public Internet protocol (IP) address from the remote PPP server; and
a user terminal operatively coupled to the access device, the user terminal configured to receive the public IP address from the access device via DHCP and to communicate with the data network.

Abstract
Method and system for providing a PPP-Bridge operating mode in a data communication system is disclosed. Upon receiving a PPP connect request from a user terminal at the LAN interface in a dial-up mode of application, or through the use of pre-configuration in a leased-line mode of application, the access device establishes a PPP session with a remote PPP server via its WAN interface. Once the PPP session is established, the access device receives a public IP address from the remote PPP server and relays the received IP address via DHCP to the corresponding user terminal. To the data network, it appears as though the user terminal is operating with the public IP address from the remote PPP server, even though the PPP session is established between the access device and the remote PPP server. This method and system supports multiple PPP sessions through the use of user profiles stored on the access device. Each user profile stores the public IP address of a PPP session corresponding to its respective user terminal.

20. A method of providing a PPP-Bridge operating mode for a data network, comprising the steps of:
-
operatively coupling a remote PPP server to a data network;
operatively coupling an access device to a remote PPP server, the access device configured to receive a public IP address from the remote server; and
operatively coupling a user terminal to the access device to receive public IP addresses from the access device, and to operatively connect with the data network. - View Dependent Claims (21, 22, 23)

24. A method, comprising:
-
initiating a PPP connection;
negotiating the PPP session and receiving a public IP address corresponding to the negotiated PPP session; and
relaying the received public IP address via DHCP to the corresponding user terminal. - View Dependent Claims (25, 26)

27. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method for providing a PPP-Bridge operating mode for a data network, the method comprising the steps of:
-
initiating a point-to-point protocol connection;
negotiating the PPP session and receiving a public Internet protocol (IP) address corresponding to the negotiated PPP session; and
relaying the received public IP address via dynamic host control protocol to the corresponding user terminal.
