There are a number of ways to do this - but I'm not sure that's *really*
what you want to do ...
The best way to "control" internet access is via Proxies. Configure your
client's browsers to point to a proxy address and any "non-local" queries
will be forwarded by the client directly to the proxy. The proxy can be
configured to control Internet access as the administrator sees fit.
If you want to ensure your internal DNS servers don't forward, either
disable forwarding or configure them as "Root Servers".
