I want to configure a remote server (Windows 2012) to allow only access using RDP via VPN. Therefore I should restrict access to the public IP of the server and only allow the private IP access. In addition I would need the port 80 to be open for public. All the other ports should be closed from the public.
I need to do this for security reasons as there are a lot of login attempts.
I tried to make a rule as a test to block an IP address, and then allow it in another rule. The rule that overrides the other is to block an IP. Therefore I cannot make a rule to block every IP, and another to allow only the specified, only a rule in which I can allow every IP and block the specified.
