I just cannont solve this IGMP annoucement

  • Hiya all, please bare with me, since i know that this issue have been mention before but for me is a nightmare. I just cant solve the IGMP annoucement killing. Im running latest PS 1.22 version.

    • Iv created a firewall rule to block the exact annoucenment
    • Im pretty sure the firewall rule setting is accurate for my purpose.

    Still im getting IGMP annoucement from <- adsl modem (bridgemode). Iv called ISP tech and they went through the modem settings and cannot find a solution to this issue either. So im here and kinda stuck. Please take a look at pictures attached and see if you guys can firegure somethin out.

    All helps much appriciated. Thanks in advance

    Maybe this a bug?

  • Looks like they have RIP enabled on that device. My ISP also sends similar messages in the event I want to run RIP.  Completely harmless I would imagine, if you don't want to see them in the log, just make a rule that doesn't do logging.

  • I thought iv made one, look at picture above, the log ticker is off, or what rule are you talking about ?

  • What I did was create a rule for IGMP traffic and unchecked the log option (default).  My ISP sends them once every minute.

  • I tried turnin on the raw filter log, this what it shows,

    pf: 127. 474922 rule 30/0(match): block in on fxp0: (tos 0xc0, ttl 1, id 53513, offset 0, flags [DF], proto IGMP (2), length 36, options (RA)) > igmp query v3

  • Try disable IGMP-Proxy on your modem if you can.

    Else you'll need to unpick Block private networks and Block bogon networks on wan interface and change your IGMP rule to a allow rule.

  • Maybe if you correct the destination in your WAN rule from  to  it triggers and blocks?

    Yea, i saw that misstake in the firewall rule and have corrected to, still same result.
