I'm trying to restrict RDP access so that only people on the WAN and LAN can access the terminal services box, along with the possibility of a few external IP addresses. We're on Windows 2008. In Windows Firewall, I've gone into 'Inbound Rule' and chosen RDP->Properties->Scope.
Within the scope, I've added the internal range which is 10.0.0.1-10.0.0.254.
Then I've added the external IP. Apply, OK.
If I try to log onto remote desktop using the local IP 10.0.0.15 (that's the IP), it won't connect me. If I enter the external IP, then it does.
Does anybody know why this happens? And how this can be fixed?
Thanks a lot
