IPv6 MLD packets blocked

[Bernhard Schmidt]

Hi,

I'm currently trying to enable IPv6 multicast forwarding on my FreeBSD 
home gateway. With both pim6sd and xorp I had the problem that MLD (IGMP
for IPv6) from clients did not come through to the appropriate daemon
and therefor groups are never subscribed.

This seems to be a problem with pf. When I disable pf with "pfctl -d" it
works like a charm; when I enable pf again, even with the simple ruleset 

pass all

it breaks. I've uploaded a sample of a MLD packet to
