I wanted to know if I were to set up a proxy server on a computer could I have another computers internet access blocked and allow strictly email with the proxy? I am trying to set something up to this effect for my workplace. We have constant abuse with our computers on our factory floor so internet has been restricted by pointing the computer to itself as a gateway. Nobody here is really computer literate so that works good enough. We dont have a server set up, everyone is on a workgroup.
