I have a few internet facing Windows (2008 R2) RDP servers and a user that I only want them to have access to the RDP server when they are on our local subnet, but allow the other users to have external access.
Is it possible to limit the RDP access of the user to the internal network only? Better yet, is there a way to limit a group's RDP access by IP?
I looked at using the Windows Firewall, but didn't see anything about limiting a specific user or group's access. I checked some of the group policy setting and could't find anything related to RDP access by IP.
