Hello,
I have a single server/DC that I just deployed. I have installed the RRAS role and NPS. I'm attempting to get the VPN up and working but for some reason the IPv4-General "Internal" interface is showing as not available. I've attempted to resolve this by using both the DHCP relay agent as well as setting a static IP pool and DHCP exclusion range. I've rebooted the server multiple times and deleted/rebuilt the RRAS config several times as well. Nothing seems to work. The Remote Access event viewer log doesn't show any useful information.
