MinimServer and endpoint on different subnet

[Frodo]

I'm sorry that I was away quite a while. In the meantime, I have experimented a little with Tailscale to integrate the two subnets. I'll be back in apartment #2 next week and can check my installation.

I have installed DietPi and Tailscale on the RPi in #2 and hope to find a solution with the software available under DietPi (e.g. GMediaRender), where I can specify the MinimServer IP address as with Foobar.
