igmp query v3

[starikarp at dismail.de]

Hi!

My system is FreeBSD 12.0-RELEASE-p10 (amd64) and I start learning ipfw
firewall.
I have a line:
cmd 01090 deny log all from any to 224.0.0.0/4 in via $pif

but I never seen anything about blocking igmp.
Mine pf firewall settings block all the time and I get:

listening on pflog0, link-type PFLOG (OpenBSD pflog file), capture size 262144 bytes
2019-10-05 06:47:08.677668 rule 12/0(match): block in on bge0:
192.168.1.1 > 224.0.0.1: igmp query v3 [max resp time 1.0s]

Why ipfw doesn't block anything, please? What I doing wrong?

Thank you.
