Hello,

is IPv6 supported for upstream servers? I try to setup an ipv4 to ipv6  
proxy:

I configured it like this:

server {  
listen 188.40.110.21:80;  
server\_name [foobar.de.ip4.zu-con.org](http://foobar.de.ip4.zu-con.org);

```
 location / {
   proxy_pass http://[20a1:and:so:on::1]:80;
   proxy_set_header Host foobar.de;
   proxy_set_header X-Forwarded-For $remote_addr;
 }

```

}

and the variation:

server {  
listen 188.40.110.21:80;  
server\_name [foobar.de.ip4.zu-con.org](http://foobar.de.ip4.zu-con.org);

```
 location / {
   proxy_pass http://foobar.de:80; #foobar.de has just a AAAA record
   proxy_set_header Host foobar.de;
   proxy_set_header X-Forwarded-For $remote_addr;
 }

```

}

and also:

upstream \_foobar {  
server [2000:and:so:on::1]:80;  
}

server {  
listen 188.40.110.21:80;  
server\_name [foobar.de.ip4.zu-con.org](http://foobar.de.ip4.zu-con.org);

```
 location / {
   proxy_pass http://_foobar;
   proxy_set_header Host foobar.de;
   proxy_set_header X-Forwarded-For $remote_addr;
 }

```

}

regards,

Matthias
