Jellyfin UPNP/DLNA with Docker Container

Edit: its on a fresh installed OMV 7

Tried to get Jellyfin with upnp working, without success:

With the standard setting it was expected not to work, because it needs Multicast UDP:

ports:

- 8096:8096

- 8920:8920 #optional

- 7359:7359/udp #optional

- 1900:1900/udp #optional---

But with host mode it still does not work:

network_mode: host

# ports:

# - 8096:8096

# - 8920:8920 #optional

# - 7359:7359/udp #optional

# - 1900:1900/udp #optional

% sudo nmap -sU -p 7359,1900 192.168.X.X (on another machine)

PORT STATE SERVICE

1900/udp closed upnp

7359/udp open|filtered swx

---

With ipvlan L2 it is even more strange. Sometimes the 1900 port shows up, most of the times it doesnt (via nmap). Jellyfin client on iOS doesnt find the server via autodiscovery

What do i miss?

Jellyfin is running fine. I guess its a docker host/container problem with the UDP multicast port for upnp. Apple TV can discover the Jellyfin server, the iOS App cant. And like written, the 1900 port is not open from the network side...

I did put the jellyfin DLNA loglevel on debug already but didnt see anything, need to dive in further

"Serilog": {

"MinimumLevel": {

"Default": "Warning",

"Override": {

"Microsoft": "Warning",

"System": "Warning",

"Jellyfin.Plugin.Dlna": "Debug"

}

},

Thats why i ask here if something is blocking on a vanilla fresh installed OMV 7....

P.S. if you read my first post it is even strange on ipvlan L2 ... there the host should be not interfering
