Damian, What you could do is setup two networks, one in a trusted zone the other is not, All your users go into the untrusted zone. Your Proxy sits in the trusted zone and reach out to the internet. The users in the untrusted zone can only get to the proxy. The proxy is the only one with a right to go out to the internet. You could accomplish this to if your router allows ACL, You could deny all outbound traffic except that comes from the proxy server. Good luck. ______________________________________________________________________________ | John R.

Squid is strictly an HTTP proxy, and (to the best of my knowledge) can only intercept HTTP communications (not HTTPS, or any of the rest). Some services can be explicitly told to use an HTTP proxy, but what you are attempting is just not going to work. > Chris
