服务器添加cloudflare白名单

做博客网站之类基本上都有被攻击的风险,国外的服务器的话一般都可以套个cloudflare来防攻击,但是即使DNS服务器用cloudflare的,源服务器IP还是有一丢丢的几率被找到,那么这个时候可以给服务器添加cloudflare白名单来防止大流量攻击。
官方教程:
在iptable里添加白名单(结合cloudflare官方给出的IP和iptable命令格式):

iptables -I INPUT -p tcp -m multiport --dports http,https -s 173.245.48.0/20 -j ACCEPT
iptables -I INPUT -p tcp -m multiport --dports http,https -s 103.21.244.0/22 -j ACCEPT
