Sorry, I'm jumping into the middle of this becasue I
just started following this thread now... But here's
my two cents...

First off, a lot of good information has flowed
through here.  If it leaves your head spinning or
doesn't make sense straight away, I'd fall back on
Dan's earloer suggestion "get a router" ;-)

Let's clarify...  Generally speaking, most high speed
ISP's will only allow you to connect one machine to
the internet through their service.  They assign that
machine a specific IP address that it can use to do
so.  If you have multiple machines and want them to
access the internet as well, they will usually sell
you additional IP addresses at additional cost. Should
you wish to go this route, a hub or switch will do
just fine for you with no other equipment.  But
frankly, your paying a premium for high speed access
anyway.  By adding a router (or a proxy server) you
can connect many machines (more than you'll ever use)
onto the single internet connection without having to
pay for additional IP addresses from your ISP.

The difference between a router and a proxy server is
that the router is a piece of hardware, and is
self-contained, easy to setup, adn easy to maintain. 
It also doesn't require additional overhaed on any of
your computers.  A proxy server will require two
network cards in one of the machines (the one it's
installed on) and it is a piece of software that runs
on that particular machine and basically emulates the
same functions as the router.

If you don't know all the ins and outs of setting up
an IP network, subnetting and the like, then do
yourself a favor, don't try to setup a proxy server,
and go buy a router.  It's an investment that will
cost you less than $100, is basically plug and play,
and will be well worth it for all the headaches you'll
save.

If your a die hard and want to configure the proxy
server, then by all means, set it up.  Generally, if
you have the extra network cards, you can setup the
proxy server for free and save yourself the $50-$70
the router will cost you.

If your going to setup a proxy server, put it on your
fastest machine!  It will take up processing power
(not a lot) from teh machine it runs on all the time
(whether your online or not).

I've gotta tell you...  I've got a good background in
networking.  I've run both at home.  A year ago, I
shut down my proxy server (running on a Windows 98 PC
and servicing three other windows PC's and three Macs)
and bought a router.  I was tired of the headaches and
hassles of upkeeping the proxy server and making
everythign work.  I have no regrets.  The router does
everythign my proxy server did, but I don't have any
of the overhead work that I had before.

I would totally recommend a router to anyone wnating
to share an internet connection who doesn't have a lot
of experience in metworking.

As for Mike (I think it was) who bought a hub (or a
switch - I don't remember) cause the guy at the
computer store told him thats what he'd need...  The
guy at the computer store was right, if you want to
pay your ISP additional cash for each machine you want
to connect.  Otherwise, the router is what you wanted.
 But, since you have the hub, you could buy a router
without an integrated switch which would be a little
cheaper...  keep your hub and use that as well.  Would
it be cost effective? Dunno... Have to look and see...

Cheers,
Sionnach
