Remote Desktop Protocol (RDP) is a crucial tool for IT professionals, enabling remote access to systems for administration and troubleshooting. Understanding the network ports that RDP uses and how to configure them is essential for optimizing performance and ensuring security. This article provides a comprehensive guide to RDP network ports, with a focus on TCP and UDP protocols.
Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft that allows users to connect to another computer over a network connection. This connection enables remote management and access to applications, files, and network resources as if you were physically present at the remote machine.

RDP works by transmitting screen images from the remote computer to the client device and sending input from the client device (such as keyboard and mouse actions) back to the remote computer. This two-way communication is facilitated by RDP's ability to compress data and manage network bandwidth efficiently.
Understanding whether RDP uses TCP or UDP is fundamental to configuring your network and firewall settings appropriately. Let's delve into the details of these protocols and their relevance to RDP.
Transmission Control Protocol (TCP) is one of the core protocols of the Internet Protocol (IP) suite. TCP is designed to provide reliable, ordered, and error-checked delivery of data between applications running on hosts communicating via an IP network.
For RDP, TCP port 3389 is the default port used. This port must be open in the firewall to allow RDP traffic. The use of TCP ensures that RDP sessions are stable, with data transmitted reliably, making it suitable for tasks requiring high accuracy and consistency, such as remote administration and troubleshooting.
User Datagram Protocol (UDP) is another core member of the Internet Protocol suite. Unlike TCP, UDP is connectionless and does not guarantee the delivery, order, or integrity of data packets.
Since RDP 8.0, UDP port 3389 can be used to improve performance. When available, RDP will attempt to use UDP first for its low-latency benefits. If the UDP connection fails, RDP will revert to TCP. This dual approach allows RDP to leverage the speed of UDP while maintaining the reliability of TCP as a fallback.
Proper configuration of RDP ports is essential to ensure optimal performance and security. Here are detailed steps to configure RDP ports on Windows Firewall.
Ensure that accounts accessible via RDP have strong, complex passwords to prevent unauthorized access. Implementing password policies that require a combination of uppercase letters, lowercase letters, numbers, and special characters can enhance security.
Network Level Authentication adds an extra layer of security by requiring users to authenticate before establishing a session. This prevents unauthorized connections and reduces the risk of attacks.
Restrict RDP access to only those who need it. Create a specific user group for RDP access and add users accordingly. Regularly review and update user permissions to ensure only authorized personnel have access.
Keep your system and RDP software updated with the latest security patches. Regular updates help protect against vulnerabilities and improve overall security.
