Hello,
I have discovered that I had a multicast issue for years I did not know about.
I use a FreeBSD (opnsense) setup as router for my home network and have
igmpproxy for IPTV. Somehow everything seems to work, until I realized that my
ISP was making a DoS with multicast. It is pretty much what was described years
ago here:
https://forum.netgate.com/topic/62591/igmp-issues-causing-isp-to-perform-multicast-dos-on-my-pfsense/7.
But the solution of not using FreeBSD seem weird. So dug a lot learning about
Multicast IGMPv{2,3} etc in the process. Here is an abstract of what I found:
Which version of FreeBSD is this (uname -a) ?
There has been some fixes in the multicast area from time to time, and
you should make sure you've got all the fixes incorporated in the kernel
you are using, typically by testing a kernel based on a -stable or
-current branch of FreeBSD.
