I'm running Windows Web Server 2008 R2 with IIS 7.5, I need to secure one site to be used internally only from 10.0.0.0/8. IIS is running normally now. My current sites are bound to the internal IP address and serving content to the Internet.
I can't find the IPv4 IP and Domain Restrictions module. This module is allegedly named IpRestrictionModule, but I don't see it in my modules list either. All Windows critical updates are installed.
All of the posts I find for IIS 7 (or 7.5?) mention this module, and I don't have it. How can I install/setup this module.
