GeoIP FirstNonPrivateXForwardedForIP

[Keyur]

Hi,

My website does country based redirection based on result obtained from
GeoIP against IP.

I am facing a problem where GeoIP does not work as first IP in the
X-Forwarded-For has Private network address. (Say 192.168.1.1)

I know GeoIP on private network would fail but the X-Forwarded-For also has
the public IP along with Private IP.

Eg : 192.168.1.1, 115.97.213.63 - - [Timezone] ......

In some cases where multiple proxies are involved it would show :

192.168.1.1, 115.97.213.63, 115.97.213.12 - - 

I want GeoIP should be done on the first non private ip. I could achieve
this in apache using GeoIP module directive called
"FirstNonPrivateXForwardedForIP"

How to do this in nginx ?

Kindly suggest

Regards,
Keyur
