Re: Disable internet connection

Why reinvent the wheel? Disconnect your entire LAN from the
internet and provide a proxy server. You can control who can
connect though the proxy server using user accounts and passwords.
Micorsoft's ISA Server will do the job of course, and there are
many third party proxies out there as well...
