Sadly in the 4 years I’m using it jellyfin still couldn’t figure out how to correctly display series season covers and has some streaming bugs (no audio when audio is DTS and PGS subs are enabled ect)
Thanks for the pointer, it seems it’s an DNS issue after all (IT’S ALWAYS DNS). Routing all traffic through the tunnel forces the Clients to use the DNS server of the LAN. Without, my internal websites (which use a public domain namespace) are sometimes resolved with a public DNS. So the browser doesn’t request test.home.network (10.0.0.100) but test.home.network (1.19.72.59).
Wouldn’t this tunnel everything? I just want 10.10.10.0/24 and 10.0.0.0/24 (VPN and LAN IP range to get tunneled). I also don’t know how this would mitigate this issue
