What is RDP Port?
RDP PORT is a network protocol used by Microsoft Windows Terminal Services and Remote Desktop. RDP features are also based on the T.120 protocol described by the International Telecommunication Union (ITU), which is the protocol used in the Microsoft NetMeeting remote conference software. Clients that support this range from most Windows 32-bit operating systems (including Windows CE and PocketPC) to other operating systems such as Linux, FreeBSD, UNIX Solaris, and Apple Mac OS X. By default, the server opens. This protocol will open TCP port 3389.
Properties
This Protocol Supports the Following Features:
- Supports 32-bit color depth, of course, except 8-bit, 15-bit, 16-bit and 24-bit.
- 128 bit encryption uses the RC4 encryption algorithm number.
- Support for connecting the Transport Layer Security (TLS) protocol.
- Audio orientation, so the actual sound from the server can be heard on the local client machine.
- File system redirection, so that the local file system that stores the user files is available in a terminal server session.
- Printer redirection, so users can use server-connected printers as if they were working with a local printer.
- Directed ports, so users can access local serial and parallel ports directly.
- The dashboard can be used between a local computer and a remote computer.
Changing the Listening Port for Remote Desktop on Your Computer
When you connect to a computer (Windows or Windows Server client) via the Remote Desktop client, the Remote Desktop feature on your computer "hears" a connection request from the specified hearing port (3389 by default). By changing the registry, you can change the listening port on a Windows computer.
- Start the recording editor. (Type regedit in the search box.)
- Follow all of the following registry subkeys: HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ Terminal Server \ WinStations \ RDP-Tcp \ PortNumber
- Click Edit> Change, and then click Decimal.
- Type the new port number, then click OK.
- Close all registry editors and start shutting down and restarting your computer.
The next time you connect to this computer using the Remote Desktop connection, you must type a new port. If you are using a firewall, make sure that you configure your firewall to allow connection to the new port number.

Connecting to a Windows Remote Desktop Using a Port Different From TCP RDP Port 3389.
There are many reasons you might want to connect to a Windows Remote Desktop from a different port, or ask you to listen to a different port than Remote Desktop. The main reason I want to configure this is that if you have a network scan every few months and you have an external port that listens to them, it will suspend your service to reduce viruses, spam, and improve your service. A business account that allows you to run the server.
I want to be able to connect remotely to the Windows Vista box in my home and one of the ports included in my ISP scan list is the TCP RDP (Remote Desktop Protocol) port 3389. and use your direct router directly to NAT on a new port, or it is recommended that you use the Port on your router to route other ports on a Windows computer running Remote Desktop from the external IP address to the RDP 3389 TCP port. The following describes how to connect to a port other than the default port 3389 from TCP port on the Remote Desktop client.
Use Remote Desktop to Connect to Ports other than TCP Port 3389:
However, my suggestion is that you can run RDP on port 3389 by default and use your router for Port Forward ports that are different from external IP addresses on computers running Remote Desktop. If you are using a router running DD-WRT, you will enter, click the NAT / QoS tab, click the Port Forward sub-tab, add the port forward, click the Save button, then click Apply. The following is an example of the DD-WRT port replacement screen.
