Windows XP has ICS built-in.
 
***Edit***
 
Shows how well I read. I didn't notice your comments on the built-in ICS support. Oh well. If you are using dial-up, I believe there are some third party products that will work. You may want to check the compatibility list on the front page of this site. For DSL or Cable, using either a LinkSys or D-Link router will be your best bet. Now, if you have an USB broadband modem, you'll have to go with a software solution for now. Several companies are working on a router for USB modems, but I don't think any of them have come out with one. Check with LinkSys, they are the most recent ones I've seen working on it.

i have EXACTLY the same question than RaK : i want a proggie to share my internet connection, but N.O.T ICS, because it doesn t allow passive mode, and it's limitated...
I tried Sygate, Winroute (Makes CRASH WinXP) and Wingate... none of them worked..
Please help!

same question here
 
For now i'm using built in ICS and it works fine. But i'd like another solution tho.

use a router.

Read my posting here about smoothwall: http://www.ntcompatible.com/vb/showthread.php?s=&threadid=16847

That is not a solution, and i add that i don t either want to buy a router... it MUST be a solution, like there was a solution in WinME that was to use Winroute... maybe a later version..

UP!!
