Hate to disagree, but I think you really wanted a Router, probably with a
firewall built it, and possibly with wireless capabilities as well.

Typically, the service provider only allows you to have a single IP address,
usually dynamically assigned. They think that corresponds to one computer.

The router will do NAT, making all the internal computers look like one
external one. It will also limit how much of your internal network is visible
from the outside. Most routers also include a 4-port switch.

Prices are under $100 US.

Some routers even have embedded linux internally, and there are projects that
allow custom versions of linux with special features. See OpenWRT.org
