Where are the system-wide proxy server settings?

How do I make a proxy server that allows other computers to access my internet connection through the proxy, but will not allow them to access my internet connection directly?

I have a server and a switch. I would also like to provide wifi access under the same conditions.

Have you taken a look at this question? - Where are the system wide proxy server settings? – Nitin Venkatesh Aug 8 '12 at 4:24

Take a look at this fine project.

Also, looks like you might use also ipcop that resolve that wireless access in a secure way.

I guess I am still wondering how I block access to the internet... Let me clarify. What is to stop someone from using the internet without using my proxy? – Jason Aug 7 '12 at 18:21
