I’ve been wanting this feature for a long time, and I may finally have it.
I am running ROON on an Apple Mac Mini. I have an Amplifi router. Using their transport app. I am able to VPN into my router, and (I truly don’t fully understand why) BOOM! Roon comes up and plays normally. It’s a smidge slow, but nothing major. And considering the fact that I’m in Japan when home is in North America, I’d say that’s extremely strong.
Currently, I’m on WiFi, I’ll test a bit later to see if LTE works as well. I am hopeful.
