Your problem is because the default ipv6_prefer policy prefers IPv4 addresses when the source IPv6 addr is in 2002::/16, the destination IPv6 address is not in the same prefix, and IPv4 addresses can be used for the both. It is not a bug of the selection mechanism. The ipv6_prefer policy is defined in RFC 3484 2.1 and this policy chooses a src IPv6 addr in 2002::/16 only if the dest addr is also in the same prefix. You can remove the special rule for 2002::/16 by putting the following lines as /etc/ip6addrctl.conf and reboot the system: ::1/128 50 0 ::/0 40 1 #2002::/16 30 2 ::/9620 3 :::0:0/9610 4 By installing the above, IPv6 address will be preferred even if it is in 2002::/16. I am still not sure why there is a difference between 8.X and 9.X on your box because the code is almost the same. I guess no policy was installed when you used an 8-stable system. -- Hiroki pgpdWwDjVjkUo.pgp Description: PGP signature

AFAIK, recent Firefox implements Happy Eyeballs. So, I suspect it
doesn't obey RFC 3484, anymore.

9.0-beta3 preferring ipv4 over ipv6 with ipv6_activate_all_interfaces="YES"
Hello list, I just upgraded my home workstation to 9.0-beta3 amd64. It seems like my web browsers are preferring ipv4 over ipv6 after the upgrade, I tested Firefox and Opera. After digging into rc.conf(5) I found this bit: If ``AUTO'' is specified, it attempts to read a file /etc/ip6addrctl.conf first. If this file is found, ip6addrctl(8) reads and installs it. If not found, a policy is automatically set according to ipv6_activate_all_interfaces variable; if the variable is set to ``YES'' the IPv6-preferred one is used. Otherwise IPv4-preferred. The default value of ip6addrctl_enable and ip6addrctl_policy are ``YES'' and ``AUTO'', respectively. I already have ipv6_activate_all_interfaces="YES" in /etc/rc.conf so ip6addrctl_policy _should_ be "ip6addrctl_policy" if I am reading this correctly. But my browsers still prefer ipv4. Is this a bug, or do the manpage need updating ? Before the upgrade to 9 I was running 8-stable which preferred ipv6 like I would expect.
