Hi – Installed Roon Core x64 on Ubuntu 17.04 last night on my home LAN; current versions of everything. My Roon remotes work great when located on the same LAN. However, I can’t get the Roon remote to connect from any network outside my LAN, on a different subnet, connected through an “allow all” VPN.
Home LAN1: 172.16.0.0/16
Remote LAN2: 10.0.0.0/16
I’m able to ping the Roon Core server from the remote LAN, and ports 9100/9101 appear open when I run nmap. No ports are blocked. I’ve tried several clients from LAN2 – none can connect to the server, even when I specify the IP and Host and click “scan.”
I also tried port forwarding UDP 9003, TCP 9100-9200 on the LAN1 router and connecting from both LAN2 and through my cell phone’s network to the public IP. Also can’t connect. When I view the logs on the server, a connection attempt doesn’t register.
What gives? Is it possible to access Roon Core server from a different subnet? Any suggestions? Everything works great when I’m on the same network.
