Visitors's IP not from Cloudflare


#1

I’m just get on Cloudflare WAT 2 days.

Today, I find form error log, one visitor from China show its China ISP IP. Its a bad visitor, hit my website 200 times, I block the IP.

Is it bypass Cloudflare WAF?

If you’re using Digital Ocean or Vultr (maybe others as well), they have a firewall feature where you can allow IPs, and deny everything else. It will take the load off your server if someone bypasses Cloudflare to attack your site.
