Windows remote desktop through NAT

natremote-desktopwindows

I just setup remote desktop to my Windows server 2012 R2. Thi works great from LAN. How can I setup remote desktop from outside of the LAN. I have tried NAT like this:

192.168.1.200 = windows server's IP

192.168.1.200:80 -->> my_public_IP:10200

when I want connect to it like this, it doesn't work. Maybe other local port..?

Best Solution

Windows vista onwards provides secure RDP connectivity over IPv6 without port forwarding configuration on NAT. This feature is called WICN & it gives a unique name to your computer using which you can directly RDP to the machine.
