Abstract
Methods and apparatus are provided for coupling a single computer, or small network of computers, and associated peripheral devices, to a wide area network, such as the Internet. The apparatus enables the devices to share a one or more IP addresses. The apparatus further enables remote access to the associated peripheral devices.
Claims22
A method for communicating data between a first computer and a second computer, the method comprising:
- accepting a first data packet from the first computer;
- modifying a source field in the first data packet;
- transmitting the modified first data packet to the second computer;
- accepting a second data packet from the second computer, said second data packet being an HTTP request;
- searching a table for a record correlating data in the source field of the first packet and in the destination field of the second packet;
- if said searching is unsuccessful, examining the second data packet for a Uniform Resource Locator or Uniform Resourse Name to identify a destination of the second data packet;
- modifying a destination field in the second data packet, where the destination field identifies the first computer;
- and
- transmitting the modified second data packet to the first computer.

Apparatus for communicating data from a first computer to a second computer, the apparatus comprising:
- a gateway computer having a first interface for communicating with the first computer and a second interface for communicating with the second computer;
- and
- a processor programmed to accept a first data packet from the first computer via the first interface, modify a source field in the first data packet to form a modified first data packed, and then transmit the modified first data packet to the second computer via the second interface;
- said processor is programmed to accept a second data packet from the second computer via the second interface, said second data packet being an HTTP request, modify a destination field in the second data packet to form a modified second data packet, the modified second data packet identifying the first computer, and then transmit the modified second data packet to the first computer via the first interface;
- said processor is programmed to search a table for a record correlating data in the source field of the first packet and in the destination field of the second packet, and to examine the second data packet for a Uniform Resource Locator or Uniform Recourse Name to identify a destination of the second data packet if said search is unsuccessful.

A gateway for communicating data between a first computer and a second computer, comprising:
- first interface for communicating with the first computer;
- a second interface for communicating with the second computer;
- and
- a circuit to accept a first data packet from the first computer via the first interface, modify a source field in the first data packet to form a modified first data packed, and then transmit the modified first data packet to the second computer via the second interface;
- said circuit to accept a second data packet from the second computer via the second interface, said second data packet being an HTTP request, modify a destination field in the second data packet to form a modified second data packet, the modified second data packet identifying the first computer, and then transmit the modified second data packet to the first computer via the first interface;
- said circuit to search a table for a record correlating data in the source field of the first packet and in the destination field of the second packet, and to examine the second data packet for a Uniform Resource Locator or Uniform Recourse Name to identify a destination of the second data packet if said search is unsuccessful.
