IPv6 to IPv4

[Sergey A. Osokin]

Hi Rhys,

hope you're doing well.

Yes, it's definitely possible.  The following code snippet does the show:

    server {
        listen   [::]:80 default ipv6only=on;
        location / { proxy_pass http://127.0.0.1:8081; }
    }

    server {
        listen   127.0.0.1:8081;
        location / { return 200 "OK, 127.0.0.1:8081\n"; }
    }


% curl 127.0.0.1:8081
OK, 127.0.0.1:8081
% curl -g -6 "http://[::1]/"   
OK, 127.0.0.1:8081

Nginx is receiving requests on IPv6 fine, but some of my services are IPv4 only. Can Nginx receive the request on IPv6, retrieve the content from IPv4 internally, and the. Serve the context over IPv6?
