What rdp network ports are required for remote desktop connection?

[Usuflychin]

I’m setting up remote access and need to know which rdp network ports must be open. What are the default rdp network ports used by Windows and how can I configure rdp network ports securely?

I've been experiencing issues setting up my RDP connection on a corporate network and the information in this thread has been super helpful. To confirm, the standard RDP port is 3389, but some firewalls also block port 3389 (TCP) and port 3390 (TCP) for alternative connections. I've also seen some instances where port 3389 (UDP) is used for RDS connections. I appreciate the community members who shared their knowledge on this, it's really saved me a lot of time and hassle.

Remote Desktop (RDP) mainly uses:

TCP port 3389 (primary port)
UDP port 3389 (for better performance in newer versions)

These ports must be open on the firewall for a successful Remote Desktop connection.

The main RDP (Remote Desktop Protocol) network port required is TCP 3389. For some setups, UDP 3389 may also be used to improve performance. No other ports are typically needed for standard RDP connections.

RDP requires TCP port 3389 by default for remote desktop connections. It may also use UDP port 3389 for improved performance in newer versions. Ensure these ports are open on firewalls and routers to allow successful remote access between client and host systems.
