You are allready pasing them back to your backend servers with:

proxy_set_header X-Real-IP $remote_addr;



The thing you need now is that the backend webservers use this as the real
clients IP.

For Apache you can use mod_rpaf http://stderr.net/apache/rpaf/ ( just
change the RPAFheader to X-Real-IP obviosly).
For nginx you use the RealIp module (
http://wiki.nginx.org/NginxHttpRealIpModule )

For IIS I am not sure (as I dont use it) but quick googling gave something
like this http://www.winfrasoft.com/X-Forwarded-For.htm
