Q: is a VPN the only way to access MinimServer from outside the local network?

I can confirm that BubbleUPnP Server (in conjunction with the BubbleUPnP player on my Android phone) enabled me to gain access to MinimServer running on my NAS while away from home.

However, you need a good data signal for this to work smoothly and I gave up this method in favour of storing MP3 conversions of my FLAC files on a 128GB MicroSD card fitted to my phone. The only frustration with the latter method is that you lose the convenience of the metadata-based MinimServer browsing tree and have to resort to selecting music by folder and file.

An Android version of MinimServer would resolve that issue, but I suspect that Simon has plenty of other things to do with his time
