Networking 3 Computers - without a Hub

Folks,

I have a puzzle for you all.  I have the following setup:

Computer A - Connects to broadband service using USB modem
Computer B - Uses MS SQL
Computer C - Uses MS SQL

On each computer I have 3 network cards and would like to have Computer B and Computer C share the internet connection from Computer A.

However despite what I try - I cannot enable this with Xp Pro.  I do not wish to use a hub as the computers A, B & C all use MS SQL and have trouble working with all the hubs that I provide.

Any ideas how I can set this up?

Regards

going back to the original issue; I am wondering what in MS SQL (layer 7) is erroring out in a networked environment that warrents NICs (Layer 1) being directly connected to each other.  I was rather fascinated with the excerise that I previously overlooked the problem at hand.  The hubs (L1), switches(L2) or even routers(L3) do not have any direct interactions with what an app(L7) does.

Or is this actaully an excerise??

What you say makes NO SENSE whatsoever regarding MSSQL.  How is it MSSQL does work?

The better option would be to use a Switch, rather than a Hub or connecting them directly.

If you are trying for fun (as you say it's a puzzle), then you can use combination of Network Bridging and ICS to have Internet to the other 2 computer, and make all 3 talk with each other.

A hub has no settings. You just plug in cables.

I agree with Leew - we have many servers running MSSQL, and they're all attached to our network. If this causes you problems, something is misconfigured.

Regardless, you could theoretically (not recommended) do it like this:

          A                               B                                   C
USB---network1----------Net1--Net2----------------------Net1

On machines A and B, you would go into network connections, select both interfaces, right click, and bridge them.

Then, on machines A, B C you give them different IP's on the same network, with the same mask.  Machine A's USB would be the default gateway.

Note, you didn't mention Internet sharing - if you want to do this on A, you'd have to set up Internet connection sharing - and you wouldn't Bridge A.
