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 http://www.birkenwald.de/~berni/tmp/mld.dump FreeBSD heimdall.birkenwald.de 5.3-STABLE FreeBSD 5.3-STABLE #0: Wed Nov 24 00:48:49 CET 2004 root@heimdall.birkenwald.de:/usr/obj/usr/src/sys/HEIMDALL i386 Thanks Bernhard
