How to do the shared Experience in Hololens from multiple physical location or different network?

Hi,

I am trying to develop a shared experience in Hololens using a demo project which is there in Hololens Academy site.

I can able to do the shared experience using a same network, but i am not able to do the shared experience on different network or different physical location.

But in Windows website they are mentioned it will support different physical location and different network. But i am not able to crack it.

Tried MR toolkit project from Git also but not able to do it.

Can anyone please help me how to do this shared experience with different physical location.

Thanks.
