Hi,
Thanx for the reply.

Why i would like to blok it is it contains mostly ads. and here in India the dialup bandwidth is damn slow. I dont want to waste time and bandwidth trying to load those . Thats the basic idea.

I use Zonealarm basic as the fire wall and i did not see any way to block specific IP address ( a out going call). can U please explain how can i achive it ?
