Showing the real client ip (behind nat) - HELP!

Hello,
I am having a server which is behind nat (mikortik router) the client ip in the apache and nginx showing the mikortik router which is 192.168.0.254 rather than the client IP.
<?php
echo $_SERVER['REMOTE_ADDR'];
?>
I have installed many modules in the apache such as remote-ip... but no lucky.
I have forwarded the domain via cloudflare and I can take the real visitor ip, and it is shows via $_SERVER['HTTP_CF_CONNECTING_IP']
The question now how $_SERVER['HTTP_CF_CONNECTING_IP'] is working? I want to make something like this without using cloudflare.
May you help?

That's because you are using NGINX as proxy, so Apache sees any petition with the server's IP.
To find the "real" client IP you have to use
Code: Select all
<?php echo $_SERVER['HTTP_X_REAL_IP']; ?>
in PHP.
Hope this helps.
Regards.

Additionaly, I have tried another config on my Debian 7, you can modify the file:
Code: Select all
/etc/apache2/mods-enabled/rpaf.conf
And replace it with this conf
Code: Select all
<IfModule rpaf_module>
RPAFenable On
RPAFsethostname On
RPAFproxy_ips 192.168.1.150 192.168.1.151 192.168.1.152
RPAFheader X-Forwarded-For
</IfModule>
Modify the ips for the one you use on your server as proxy.
Then restart apache from within VestaCP admin area this should show clients real IP instead of the nginx proxy.
