Can also do:
In nginx.conf, in after open http {
http {

Need realip module compiled in NGINX...
For confirm if have:
nginx -V 2>&1 | egrep --color -o 'realip_module'
In the case XC:
/home/xtreamcodes/iptv_xtream_codes/nginx/sbin/nginx -V 2>&1 | egrep --color -o 'realip_module'
For obtain IPs CF updated: IN cloudflare_ips.conf FILE -->
cat /dev/null > cloudflare_ips.conf && curl -s https://www.cloudflare.com/ips-v4 | while read ip; do echo "set_real_ip_from $ip;" >> cloudflare_ips.conf; done && curl -s https://www.cloudflare.com/ips-v6 | while read ip; do echo "set_real_ip_from $ip;" >> cloudflare_ips.conf; done && printf "real_ip_header X-Forwarded-For;\nreal_ip_recursive off;\n" >> cloudflare_ips.conf
Test:
/home/xtreamcodes/iptv_xtream_codes/nginx/sbin/nginx -t
Reload:
/home/xtreamcodes/iptv_xtream_codes/nginx/sbin/nginx -s reload
NOT use CF in LBs...
