ip6fw

I'm setting up rules for ip6fw on a machine running FreeBSD 4.2-Release,
and I'm having trouble getting router advertisements and solicitations
through for smooth autoconfiguration.

I see icmp type 134 from my ipv6 router to all ipv6 devices on the 
outside interface of the firewall (as expected), but nothing gets
through to the machines connected to the inside interface. I have set

  allow ipv6-icmp from any to any 

and 

   net.inet6.ip6.forwarding=1

So I would expect the advertisements and solicitations to be accepted on
one interface and sent out the other. I wonder about the TTL, but I
would've thought (hoped) the firewall is transparent to allowable traffic.

Has anyone done this, any suggestions ?

Thanks.
