Sygate has much more flexibility than ICS. It will let you configure routing, caching and a lot of other things. How much it can do depends on what version you choose. There are a
Home and an
Office. You can see the differences yourself.
I have used the Office version and find it very flexible to use.
My best bet though for a NAT-solution is
WinRoute Pro & Lite from TinySoftware.
ICS has got a lot of known security issues which makes it lesser attractive.
I have had some stability issues with Sygate running under W2K. I think it was caused by a memory hole in the cache feature. I think the problem is fixed by now.
The Sygate server itself doesn't take up much, but if you enable cache it takes as much memory as you set the cache to.
I can't say how much ICS eats since I haven't been using it for years...
Conclusive: Go with Sygate Home over ICS. (although I would strongly recommend WinRoute or the free program WinProxy)
