Check out dansguardian and squid

working together these to programs can filter your internal web traffic 
redirecting "inappropriate" requests to another site.

Dansguardian works on a blacklist basis that is heavily categorized.

you can block by site url, words/phrases in the url, and even by web 
site content (thats where the squid part comes in, squid is a proxy 
server and pre-caches the site so the system can read the content of 
the url if needed.)

the base blacklist is downloadable once for free (from another web 
site)  after the once you are encouraged to register with a fee from 
which you derive the right to download incremental updates so you can 
keep your blacklists up to date.

Both DG and Squid are in ports.

Have fun.
