Hi,

Yeah it's changed in 9. Here's what I have, for autoconfig use with a
tunnel:

ipv6_network_interfaces="re0"
ifconfig_re0_ipv6="inet6 accept_rtadv"
ip6addrctl_policy="ipv6_prefer"

...and it works

For static I'd have:

#ipv6_network_interfaces="re0"
#ifconfig_re0_ipv6="my_end_of_tunnel_ipv6_ip prefixlen 64"
#ipv6_defaultrouter="their_end_of_tunnel_ipv6_ip"
#ip6addrctl_policy="ipv6_prefer"

but I've not tried it static yet.
