I was a bit lazy to look around if there is a solution for my problem, but I ask the same.
I have JRiver Mediacenter 25 Master License and got it running on Ubuntu and several Windows 10 operating systems. I also use JRemote on iPhone to stream my library on the go. The one on Ubuntu runs as server and others are connected to this library. I would like to control all the Mediacenters from others and it works on local network when I load the library from one I want to handle. The servers library can be loaded only on the one that I want to control and play media.
I would like to control all the Mediacenters without changing the library loaded and also outside my local network. This is possible with my miniDSP SHD (Volumio) which works as DLNA device connected to the Mediacenter on Ubuntu, but not on the Mediacenters. Is there something on the settings that could ease me with this and provide a solution?
