Sharing an Internet connection requires more than just a switch.

If you have a dial-up Internet connection, connect both computers'
network cards to the switch and enable Internet Connection Sharing on
one computer's dial-up connection.

If you have a broadband (cable modem, DSL, satellite) connection, here
are some options:

1. Get two IP addresses from your broadband provider. Connect the
broadband to the uplink port of the switch. Connect the computers to
regular ports; or:

2. Put two network cards in one of the computers. Connect the
broadband to one of them and the switch to the other one. Enable
Internet Connection Sharing on the broadband connection. Connect the
other computer to the switch; or:

3. Replace the switch with a broadband router, which has a built-in
Internet sharing capability. Connect the broadband to the WAN
(Internet) port, and connect the computers to regular ports.

In the long run, #3 is the best solution, although it costs more
initially.

A switch and a hub would work exactly the same in this setup. Neither
of them has an Internet sharing capability; both of them would require
two IP addresses from the ISP.

No. A hub is all I use, and it works fine. Only one
IP address is needed. Both of my computers are
running Windows XP, and with the Newtork Setup
Wizard, setup could hardly be quicker and easier.

OK, I'm looking at it right now. It's an Ansel Communications
"EtherHub 4001" -- definitely a hub.

> Is one computer set up as an Internet Connection Sharing host?

When I used the Network Setup Wizard to set up networking,
I selected "This computer connects directly to the Internet ..."
for one computer, and "This computer connects to the Internet
through another computer ..." for the other. Both computers
are connected directly to the hub, and my DSL modem is plugged
into the uplink port of the hub.

Bob,

I was just following these messages and wanted to remark that
this setup is not quite perfect, because all internal traffic,
data going from one computer to the other, is also sent out by
the hub on the Internet connection.

I hope that data is blocked somewhere before it leaves the
house, for performance reasons and also for security reasons.

A hardware router (using NAT = Network Address Translation)
would solve that problem. (Example: SMC 7004 VBR with firmware
version 1.23 or higher. Costs around $50, I believe.)

Internet sharing requires a router to move traffic between the
Internet and a local area network.

You have a computer configured as an Internet Connection Sharing host.
ICS is a software router. There are also hardware routers.

You're sharing the Internet connection using a software router and a
hub. A hub can't share an Internet connection by itself.

That's what I've been trying to say all along, Bob. I apologize if my
earlier replies weren't sufficiently precise.
