Пытаюсь сделать forward proxy для IPv4 & IPv6.

Для 4 все работает отлично, для 6 пытается ходить по 4.
Если указать хост у которого только 6 адрес - не резолвит.

В логе следующее:
2013/02/28 12:24:09 [debug] 5397#0: resolver qs:ipv6.l.google.com
2013/02/28 12:24:09 [error] 5397#0: *15 ipv6.l.google.com could not be

2013/02/28 12:23:09 [debug] 5397#0: *13 http upstream connect: -2

В обоих случаях коннект идет на сервер:

server {
        listen [::]:8080 ipv6only=on default bind;
        resolver [2001:4860:4860::8888];

        location / {
                proxy_pass $scheme://$http_host$uri$is_args$args;
                proxy_bind $server_addr;
        }
}


Это баг или фича?
