I am trying to configure NAT'ing on a Windows 2012 R2 VM in my VMware Workstation host so I can get to the internet and activate the OS. When I get to choosing a NIC for NAT'ing, the public one is grayed out? This is my first time doing this, so bear with me. I am trying to create a virtual environment for studying. I am doing this on my company workstation logged in as a domain admin. Any help would be greatly appreciated.
