I've had a look through the archives, but not seen anything
that struck me as relevant (but please, if there is a more
appropriate place to ask, point me in the right direction)

IPF hooks in netinet6/ip6_forward.c don't exist in 1.5.3 alpha,
but do exist in -current, is there any plans to bring the hooks
and anything else required to get IPF to firewall IPv6
traffic into 1.5 at any stage, or do I need to bite the bullet
and use -current?

thanks for any suggestions

Carl
