Hi Tim,

The only reliable and safe way is to restrict access on the gateway  
which connects the machines to the outside world by blocking  
everything, and explicitly only allowing access to hosts you specify  
(as in: your local DNS server (which should not resolve outside  
names), the library server, and perhaps a backup server).

How does your network topology look like?
