But the real challenge is sharing your Internet connection. If you are lucky enough to have a cable modem, ISDN, or DSL access, you can share it on a regular network without too much trouble, provided you know enough. Ramp also resells the Sonic Wall firewall box, which is also something you'll need to protect your home from electronic intruders and what I currently use at chez Strom.
Ramp continues to sell products with solid and clear documentation.
I do have a home LAN up and running here, after all this. That while many people have multiple PCs in their homes, getting them connected isn't going to happen quickly. The skills required are far beyond the average person's abilities. There are too few clear technology choices, and no single vendor solution. While the vendors mentioned above sell kits for connecting two computers, you may have more PCs though.
