First you need a host computer with 2 network adapters. One connects to the modem/internet the other to a network hub/router then to Nfusion and/or other computers. Run internet connection sharing wizard. Then run a proxy program. One you can try is called Admuncher. Just Google it. Under tools select scramble IP. Then check yourself at stayinvisible dot com. Running through a proxy server will slow your internet speed way down so it would be best to configure to run only for Nfusion or during manual updates.
