While I'm not 100% sure (prolly Igor or Maxim can confirm/deny) if the module changes the clients ip before other modules/internals
(like Access) but you could use the RealIP module http://wiki.nginx.org/NginxHttpRealIpModule
And bassicaly add just the required header:
real_ip_header TRUE-CLIENT-IP;
