Free Proxy with content/site blocking??

[coolamasta]

Hey all,

Does anyone know of a free Linux based proxy server that has content blocking available so I can ban certain content/categories or use a whitelist and blacklist of sites sort of thing?

Its a small project I am working on and don't want to pay for any software or buy a router with it built in but I know there must be something out there capable of this?

Cheers for any help guys

Thanks all, going to have a play with OpenDNS first but im not sure if thats going to work how I want it to because you lock down your external IP, well if you set their DNS on your router, if you set the DNS on local PC's then they wont see other machines in the network by name... Hmmm....

I have been told to try IP Cop with the squidguard add-on so might install that on an old PC and see what it does.
