IGMP sourced from WAN on 0.0.0.0 in logs



  • Hi All,
      I have block bogon networks enabled and in my firewall logs i see the following appear every 2 minutes:-

    Dec 19 09:04:07 WAN  0.0.0.0 224.0.0.1 IGMP

    Looks like multicast traffic but i don't understand why its coming from the WAN side and every 2 minutes. I have Sky HD box which has an on demand service (on the LAN) and i thought it was that initiating a connection and this was the reply, but even when its been disconnected for several hours i still see these messages.

    Any ideas?



  • Hi,

    I am also seeing these IGMP blocks and have been wondering what to do.

    In my case, instead of 0.0.0.0 I have 192.168.0.1 as the (wan) source. Destination is the same.

    Anyone have any ideas what we can do or should do?

    Thanks
