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
Bash:
echo 1 > /sys/class/net/vmbr0/bridge/multicast_router
Bash:
echo 1 > /sys/class/net/vmbr0/bridge/multicast_router
Bash:
echo 0 > /sys/class/net/vmbr0/bridge/multicast_snooping
Bash:
echo 1 > /sys/class/net/vmbr0/bridge/multicast_snooping
Bash:
echo 0 > /sys/devices/virtual/net/vmbr0/bridge/multicast_querier
Bash:
echo 1 > /sys/devices/virtual/net/vmbr0/bridge/multicast_querier
in PVE and
Bash:
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!
