Fwd: 9.2-RELEASE: IPv4/IPv6 dual stack and ipv6_prefered

[Rafael Ostertag]

Hi List

I posted the question below a while ago on freebsd-question, but
apparently nobody knows an answer. Maybe freebsd-stable is more
knowledgeable about my issue.

Hi

I have following entries in /etc/rc.conf:

 ip6addrctl_enable="YES"
 ip6addrctl_policy="ipv6_prefer"

on 9.1, this made FB pick IPv6 addresses for outbound connections.
However on the same box, after updating to 9.2, IPv6 addresses are no
longer used by default.

Looking at the output of ip6addrctl on 9.2, everything seems to be in
order, IMHO:

# ip6addrctl
Prefix                          Prec Label      Use
::1/128                           50     0        0
::/0                              40     1     3493
::ffff:0.0.0.0/96                 35     4        0
2002::/16                         30     2        0
2001::/32                          5     5        0
fc00::/7                           3    13     3295
::/96                              1     3        0
fec0::/10                          1    11        0
3ffe::/16                          1    12        0


Using ssh or wget to connect to another IPv6 enabled host, reveals
that IPv4 is used instead of IPv6.

Any ideas what might be wrong?
