Microsoft Remote Control through Gateway

[kurci2]

Hello!
I have a question about remote connection to server via Gateway.
On my android tablet i have installed Microsoft remote desktop app and i can connect to computer. I just enter hostname, username and password and gateway address.

But in Ubuntu I do not have gateway option in Remmina or krdc. So when I am in local network everything works, but I can not connect from home through Gateway.

Does anyone know how to connect through Gateway? It could be a terminal command or anything... It doesn't matter.

Thanks for help!

I have just found that FreeRdp could connect to windows remote through Gateway, but I can not get it to work. Has anyone any experiences?
