I have a Server machine that has both VPN and RDP Enables(Windows Server 2022).
The vpn base is L2TP and users have no problem connecting to the server with it.
Also the RDP port is open so users can connect to machines/login into it.
Now the question is , how can i avoid the user to directly connect to the server with RDP without vpn. Because atm users do not need vpn at all to use RDP.
Also, Is RDP secure without any Tunneling connection like vpn ?
