Need proxy server for Cyber Cafe

I'm about to start a cyber project (Internet/Network Games) there will be around 40 desktops, 2 wireless access points for notebooks.

I've been studying everything related to this project and now I need to know which proxy server I have to use? I know only about Debian.... are there other Linux systems do proxy server like Debian ??

Which one is the best ?

I welcome any hints and ideas.

Thank You in Advance

which is the best? is a topic that is asked over and over. It mostly comes down to preference. If you already know debian then why try and change that? Debian is my prefered server and desktop.

as for a proxy, Transparent proxies via Squid.
