It is assumed when we use REALIP_MODULE and purposely set REMOTE_ADDR to
real ip of our proxies in front
that this is the real client IP that GEOIP should be using.
example:
proxy of nginx in front of a fastcgi nginx.
Proxy config:
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For
$proxy_add_x_forwarded_for;
Fast cgi config:
real_ip_header X-Real-IP;
set_real_ip_from x.x.x.x;
This ends up setting REMOTE_ADDR correctly for Fastcgi nginx server, but
GEOIP parses information for
proxy connecting IP instead giving false information.
