Hi,

we try to access from a VM to udp multicast traffic from switch port connected to the pve node, vmbr0 is build with the interface and the udp traffic is in vlan 220 from sw.
the VM has no access to multicast, unicast ok.

I have tried to play with /sys/class/net/vmbr0/bridge/multicast_querier and /sys/class/net/vmbr0/bridge/multicast_snooping but nothing works.

Any idea ?
