There are two excellent open source web filters available.
SquidGuard ( http://www.squidguard.org ) filters based on lists of URLs/Domain names. It is fast, it is simple, it is reliable.
Dan's Guardian ( http://www.dansguardian.org ) is a "content" filter, meaning that it analyzes the web pages themselves to determine whether the page should be blocked or not. This is slower and more complex, but it is more pro-active than squidGuard's url/domain based filtering.
