Nginx reverse-proxy set up perfectly, but IPs are still 127.0.0.1?

Question

The proxy works fine, my distro is Ubuntu 10.04LTS (Server) and rpaf is loaded within apache, with the following settings httpd.conf:

<IfModule mod_rpaf.c>
  RPAFenable On
  RPAFsethostname On
  RPAFproxy_ips 127.0.0.1
</IfModule>

I can be sure it is loaded, for example:

#a2enmod rpaf
Module rpaf already enabled

I had force-reloaded apache, and reloaded nginx but all my connections are still from 127.0.0.1:

127.0.0.1 - - [13/Dec/2010:23:56:27 -0800] "GET /index.php HTTP/1.0" 200 1267 "-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.19) Gecko/2010031422 Firefox/3.0.19"

Why is it still localhost from external? I'll give any info if needed.

Answer 1

Doublecheck the requests from the proxy contain the x-forwarded-for header, usually that's the problem.

Answer 2

Found the problem, in /etc/nginx/sites-available/default I forgot to add the add header lines, my config now looks like so:

location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

And voila!
