Need help setting up ICS, Vista Host, XP clients

I have a Vista host that plugs into my router. I have two other older machines that I do not want to plug into my router. Having them go through the Vista machine ads an additional layer of security beyond connecting them straight to the net. Besides the Vista machine can handle the burden of the full Norton Suite, but it really slows down the older machines. I try to let the Vista machine be the first line of protection when connecting to the internet. I can put Avast! on the slower machines as it is less of a drag on resources even though it may not be as robust as Norton hopefully is.

So, the Vista machine has 2 Nics. One connects to the router. The other feeds to a switch where all 3 computers are wired to. I've tried over and over to set up ICS to no avail.

If I set the two XP clients to automatically get a network address for the TCP stuff they can't establish network connection. If I set them to static IPs, they can see each other and file share, but I still can't see the Vista host on the network regardless of if the Vista host is configured for static IP or automatic IP on the NIC that is for the internal network.

Problem 1) So, I can't even get the three machines to talk nicely through the switch and file share.

Problem 2) The only way ANY OF THE COMPUTERS see each other is when I assign static IPs on the XP machines, but the instructions for ICS say you HAVE TO use automatically assigned IPs for ICS to work.

So, I can't get the network talking AND I can't get ICS running.

I have run search after search on how to do this and haven't found any posting that get my stuff working.

Yes, I could plug all machines straight into the router, but as I already pointed out, that isn't what I want to do. Sure, it would be easier, but there MUST BE a way to get things working the way I want them to. I used to do it when the host was also XP, but when I replaced it with a Vista machine things went to poo.
 
You are a bit confused on how things work.

The computers on the router are not connected directly to the internet, they are connected to the router that handles the firewall and changing the IP address from your internal one to pass to the modem to access the net.

Without seeing what you are doing it's pretty hard to know what's wrong, but if you follow the instructions on how to setup ICS using the different network cards it should work. What is likely happening is that you are messing around with the instructions. Is Vista updated fully?

You don't even need to do what you are doing, just hook them all up to the router directly. ICS won't help you a bit with viruses as those come directly to the computers from the internet, the computer in between won't do a virus scan on the files that you put on the other computers. The only thing that sticking another computer in the middle does is it may make it harder for someone to directly attack the computers, but for home users that is extremely rare.

What you are thinking you are doing is basically putting a basket inside another basket then tossing it off a building thinking the inside basket won't fall with it. If you click on a virus file on one of the computers, that Vista machine will do nothing except pass the data along to it without any worries about a virus being there.
