Real IP not working?

[BigdinoWebmaster]

I've got nginx proxying to a lighttpd server (hosted on a DroboPro FS), and I'm using only the following four directives in the proxy location's stanza:

proxy_pass http://<proxy destination>
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;


This seems to be all that's necessary. The proxy target's access log shows the accessing client's IP for each request, not the nginx server.

You've got a lot more stuff going on in your config, though, so I'm not sure if this will be helpful to you or not.  Maybe you could comment out some directives and start with just the basics?
