How to Use Two NIC Cards in One Computer

Installing two network interfaces in one computer is not uncommon, but the process after the installation usually baffles the average computer user who wants to share the computer’s connection to the Internet with other computers. You can go two ways when sharing your Internet connection to other computers in your network, while having your computer act as the host gateway for the other computers. Both methods are relatively easy and can be done by anyone with a good command of the Windows interface.
