[CentOS] Filter web content in a LAN ?

Hi,

I installed a network of five desktops in a small town hall, all running 
CentOS 5.4. The machines are publicly, and the mayor asked me to find 
some solution to effectively filter web content, as the kids' first 
reflex is to visit the interesting bits of the Internet first, from 
satanism to porn.

One of the machines will be set up as a router anyway, since the public 
computer room gets its internet access from the town hall, and I've 
decided to make another subnet for it.

Any recommendations for that?
