Detailed explanation-1: -Remote Desktop Protocol (RDP) is a Microsoft proprietary protocol that enables remote connections to other computers, typically over TCP port 3389.
Detailed explanation-2: -Does RDP use TCP or UDP? Actually, Remote Desktop requires TCP port 3389 to be open.
Detailed explanation-3: -Remote Desktop Protocol (RDP) servers should never be directly exposed to the Internet, where TCP port 3389 can be reached directly. This is a recipe for disaster. Instead, Microsoft recommends RDP is implemented with a Remote Desktop Services Gateway server.
Detailed explanation-4: -RDP should never be open to the Internet. The internet is continuously being scanned for open port 3389 (the default RDP port). Even with a complex password policy and multi-factor authentication you can be vulnerable to denial of service and user account lockout.
Detailed explanation-5: -Step 1: Enable Remote Desktop on your computer. Step 2: Open Remote Desktop port (port 3389) in Windows firewall. Step 3: Set up Port Forwarding (Port Translation) in the router. STEP 4: Map your dynamic IP to a hostname. STEP 5: Use Dynu DDNS service to access your computer remotely.
