duckdns address. Local traffic shouldn’t be going through the VPN. It should come into the router (which isn’t using the VPN) and be forwarded over your local network to your Pi. It’s exactly how I run mine, albeit with a different dynamic DNS service
That's what I understand. And I have no problem connecting to Libreelec from my local network when the VPN is activated. The problem occurs only when trying to connect to Librelec from outside. I can only reach my router, but not my Raspberry hosting Librelec. Port forwarding should'nt be an issue as everything work fine when VPN is deactivated, am I right? I'm running out of ideas, it seems pretty simple but doesn't work, should I try a different VPN service provider?
