I'm in the midst of setting up Active Directory, and essentially, my domain would be a child domain of an existing network, and I'm trying to figure out whether the Direct Access technologies built into Windows Server 2016 can be used to accomplish a site-to-site connection between the two networks? I know that Direct Access sort of works like VPN, but that's the extent of it, except that I know that it can be set up so that any time I'm away from my primary location, I automatically have access to my network far away. But the question is whether it can be used to connect sites. A friend of mine tried to get it going, but not sure whether we're just doing it wrong, maybe? He forwarded out the correct port, but no one was able to get connected to his side of the network from far away.
