Description
I have the following section in my config file:
location ~* /get/(.*?)/(.*) {
resolver 127.0.0.1;
set $upstream_uri $2;
set $upstream_host $1;
set $upstream_url http://$upstream_host/$upstream_uri;
proxy_set_header Host $upstream_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass $upstream_url;
}
Everything works just fine as long as use ipv4 enabled domain names, but when I try to access an ipv6 site through the proxy, it doesn't try to resolve AAAA and fails:
*36 ipv6-only.host-name.com could not be resolved (3: Host not found), client: ::ffff:192.168.1.4, server: localhost, request: "GET /get/ipv6-only.host-name.com/ HTTP/1.1", host: "192.168.1.254:8000"
In this particular situation I want to use nginx as a proxy between ipv4 only and ipv6 only networks. I tried adding a few rules statically, and it works. I mean something like this works:
proxy_set_header Host ipv6-only.host-name.com;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://ipv6-only.host-name.com/;
I was wondering whether you can try resolving an AAAA record if ipv6 is enabled, and core fails to resolve and A record.
Let me know if you need help reproducing.
Thanks,
