Url blocking on one internal network

[Nyvia]

Hi

I'm trying to block an url on one of our internal networks but not from another since this one is used by our internet café and we don't want to block this url for our café users.

I'm trying my way with squidGuard but this seem to only work when you want to block an url completly…

Any suggestions would be great.
