Ignore references to UDP Port 3389. You don't need to open a port for that. Also Look at using a free dynamic naming service like No-IP.com or DynDNS that map a fully qualified domain name (FQDN) to your ISP assigned DHCP address. The way it works is you run a small updater program on one of your home PCs that contacts the No-IP.com (or
Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft, which provides a user with a graphical interface to connect to another computer over a network connection. The user employs RDP client software for this purpose, while the other computer must run RDP server software (from here). Default port: 3389 Remote Desktop Protocol （リモート デスクトップ プロトコル、RDP）は、リモート デスクトップ サービス（RDS、旧称：ターミナル サービス）が稼動しているサーバにクライアントが接続する、リモートデスクトップ用の多重チャネルプロトコルである。 Sep 23, 2019 · RDP-UDP-L or "Best-Efforts" Mode: In this mode, the reliable delivery of datagrams is not guaranteed, and the endpoint does not retransmit datagrams. The connection between the endpoints is terminated when either the terminal client or terminal server terminates the connection. This is a list of TCP and UDP port numbers used by protocols of the Internet protocol suite for operation of network applications.. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full-duplex, bidirectional traffic. Dec 08, 2016 · Changes in RDP over UDP behavior in Windows 10 and Windows 2016. When connecting to Windows Server 2016 or a Windows 10 over a RD Gateway we see 1 HTTP and only one UDP connection being established for a session. We used to see 1 HTTP and 2 UDP connections per session with Windows 8/8.1 and Windows Server 2012(R2) Attention! TCP guarantees delivery of data packets on port 3389 in the same order in which they were sent. Guaranteed communication over TCP port 3389 is the main difference between TCP and UDP. UDP port 3389 would not have guaranteed communication as TCP. Nov 01, 2012 · OK, so, i had to open UDP Port 3389 on my WAN Router. That is in addition to TCP 443. Seems obvious i guess, but took me a while ;o) I also set a GPO setting > (not sure if it is needed or not though) Computer Configuration > Admin Templates > Windows Components > RDS > RDS Sesion Host > Connections. Select RDP Transport Protocols - Use both
Here is an example to allow the RDP port 3389 traffic through FortiGate: Step1: Create the 'Service' Object for port which needs to be allowed under Policy and Object -> Services. If it is standard port, there are predefined service objects under 'service list'.

But according to RDP protocol it uses TCP protocol. and in windows 8 they have started RDP protocol on UDP protocol. I think there may be other reasons also. – Rajdip Patel May 8 '13 at 13:54
