在 Nginx 的配置文件中，添加下面的内容：

```auto
		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 104.16.0.0/13;
		set_real_ip_from 104.24.0.0/14;
		set_real_ip_from 172.64.0.0/13;
		set_real_ip_from 131.0.72.0/22;
                 real_ip_header X-Forwarded-For;

```

上面的 IP 地址可以从 Cloud Flare 的官方网站上查询到。

配置文件，如下所示。
