Dev team wants to achieve a layer 3 independant framework with
associated conntrack, so they do not have to duplicate code between IPv4
and IPv6. Tools will be called pkttables. In the meantime, stuff like
POM-ng (for 2.6) or nfnetlink/ctnetlink seems to have been
prioritorized. I am no developper, so I give you my understanding of the
situation, which can be a complete misundestanding :)

However, Yasuyuki Kozakai from USAGI project posted a couple of patches
to add IPv6 conntrack to Netfilter. Just crawle dev mailing list
archives and you will find it quick.

Use Yasuyuki patch if it works fine for you (never tested it), or use
BSD pf while waiting for official pkttables release.
