Make intranet inaccessible via internet?

Is it possible to make an intranet inaccessible via the internet?

My goal is to make the intranet accessible to internal employees (with no password prompting) but should someone come across the page via the internet, they will be prompted for a password.

So long as you configure the site with the local IP address from your LAN and not via the Public IP, there is no way for the site to be accessed via the Internet.
