Sonos' IGMP packets aren't handled properly



  • Hi,

    I've just updated to 2.4.2rc hoping it would help with Sonos but no such luck. This is what i'm getting running igmpproxy -d -vvvv:

    ignoring unknown IGMP message type 22 from 10.10.10.108 to 224.0.0.22
    RECV unk: 0x22/0x00    from 10.10.10.108    to 224.0.0.22

    This is what sonos is sending after I boot it. Any possibility of having sonos play nice with my vlans besides udp-rebroadcasting vlans broadcasts?

    Frame 1: 54 bytes on wire (432 bits), 54 bytes captured (432 bits) on interface 0
        Interface id: 0 (en0)
            Interface name: en0
        Encapsulation type: Ethernet (1)
        Arrival Time: Nov 19, 2017 18:50:17.321526000 EST



  • Your router or firewall should be placed in the same VLAN as the Sonos products as well. If this will be not so
    you must do some monkeying around and setting up all switches that are involved into your network too!

    Here is an article that is describing how to set up the switch, that all is well playing together.

    That sonos support doc shows the configuration for a cisco switch (who has those at home?) that I believe basically understand this igmp packet that I posted above and then re-broadcasts for you in the various ports/vlans. What I am asking is if it is possible to get a igmpproxy in pfsense that understands these igmp packets.
