Hello,

I'm running FreeBSD 12.1-Stable. pimd is running.
When I enabled pf, multicast traffic is dropped.

I wrote a single basic rule:

pass quick all allow-opts

but still multicast traffic is dropped. after pfctl -xm, dmesg shows this
error:
pf: dropping packet with ip options
pf: dropping packet with ip options
...

What is the solution?
Thanks
