[SOLVED] DLNA/UPNP/IGD multicast with Proxmox KVM?

[renne]

Hello,

I'm trying to get multicast working with Proxmox KVMs on a bridged network (vmbr0).

Setup:
- Proxmox 7.3-3 on bare metal with 1 Gbit/s NIC connected to AVM Fritz!box.
- VM with yunohost + Homeassistant
- tried VirtIO-NIC and eth1000-NIC
- Firewall off for VM

I tried the following settings

echo 1 > /sys/class/net/vmbr0/bridge/multicast_router

echo 1 > /sys/class/net/vmbr0/bridge/multicast_router

echo 0 > /sys/class/net/vmbr0/bridge/multicast_snooping

echo 1 > /sys/class/net/vmbr0/bridge/multicast_snooping

echo 0 > /sys/devices/virtual/net/vmbr0/bridge/multicast_querier

echo 1 > /sys/devices/virtual/net/vmbr0/bridge/multicast_querier

in PVE and

echo 2 > /proc/sys/net/ipv4/conf/vmbr0/force_igmp_version

in PVE and in VM.

All UPNP and DLNA devices in LAN and WLAN find each other but devices in (W)LAN and VM can't find each other.

Does anyone have an idea how to solve this?

Thanx for any hint

The problem was not Proxmox but Yunohost.
I couldn't figure out what is going wrong in Yunohost, but a Homeassistant KVM/Proxmox image works fine.

Only the Homeassistant OS image supports UPNP. Other Homeassistant installation types do not support UPNP!
