Filter some PCs on a LAN

Hello,

I've a small LAN with 7 PC with Windows OSs. Recently I set up an ADSL connection with a Speed Touch Pro router. Now I need to block some of the PCs to access internet. Do you have an idea?

Thanks.

Well it depends how u have shared the internet connection..
If u have enabled Internet connection Sharing, then remove the gateway setting on the computers, that u don't want to access the net. That shud be enuf.
Or u could download this proxy software from this site www.networkingfiles.com/Proxy/Proksi.htm
Its a very simple software to use, and best of all its free.
