Hi,

I am struggling to get multicast working in a lxc unprivileged container.
the lxc-container did not receive any package at udp port 1900. Tcpdump in the container shows nothing.
tcpdump on the bridge in the proxmox host shows that there are packages.
Any hints?
it is a ipv4 und ipv6 problem
echo 1 > /sys/devices/virtual/net/$IFACE/bridge/multicast_querier
echo 0 > /sys/class/net/$IFACE/bridge/multicast_snooping

did not help.
the lxc-container firewall from proxmox ist off.
 
I have been unsuccessful getting ipv4 multicast to cross my linux bridges to my ruckus icx7150 switch, I can get ipv6 multicast.

Some folks have no issue ... others no luck with multicast. Not sure what the magic combination is.
