Real IP for Nginx / Laravel Forge when using Cloudflare

If you use Cloudflare, you’ll need to configure Nginx to provide the real IP addresses, you can do this by installing

apt-get install nginx-extras

Then edit /etc/nginx/nginx.conf and within the http block add:

#CloudFlare
set_real_ip_from 199.27.128.0/21;
set_real_ip_from 173.245.48.0/20;
set_real_ip_from 103.21.244.0/22;
set_real_ip_from 103.22.200.0/22;
set_real_ip_from 103.31.4.0/22;
set_real_ip_from 141.101.64.0/18;
set_real_ip_from 108.162.192.0/18;
set_real_ip_from 190.93.240.0/20;
set_real_ip_from 188.114.96.0/20; 
set_real_ip_from 197.234.240.0/22;
set_real_ip_from 198.41.128.0/17;
set_real_ip_from 162.158.0.0/15;
set_real_ip_from 104.16.0.0/12;
set_real_ip_from 172.64.0.0/13;
set_real_ip_from 2400:cb00::/32;
set_real_ip_from 2606:4700::/32;
set_real_ip_from 2803:f800::/32;
set_real_ip_from 2405:b500::/32;
set_real_ip_from 2405:8100::/32;
real_ip_header CF-Connecting-IP;

Save the file, restart Nginx and then you’ll see the real user IP address within your app. You can read more about this on Cloudflare’s website.
