Add a list of IP adressess to firewall block list

Security
#1

Hi , the CDN of my website is on Cloudflare ( free version)
I was under attack, unfortunately Cloudflare couldn’t protect me against this attack but , after removing my dns from Cloudflare , I have a list of ATTACKERS IP, so now I know which IPs where attacking.
My question is : how can i import full list of my IP addresses to Cloudflare firewall ? there are more than 500 IP and i can not add them one by one.
thanks.

================
edit: in list section I added a list and added all my Ips then I went to firewall and added a rule to block all IPS in the list but
its not working!!
any help?

I assume you mean https://dash.cloudflare.com/?to=/:account/configurations/lists, right?

That’s generally a possible approach and will work if you configured it correctly.

  • Which domain is it?
  • Post a screenshot of your firewall rule.
  • Post a screenshot of your firewall rules list.

And generally, I’d probably rather check if these really are all addresses from different networks, otherwise I’d block rather by CIDR or ASN.

That domain is currently not using Cloudflare.

yes. because I couldn’t fix it , I migrate to other CDNs to check. but its temporary and i will come back.
should I be here so you can check my rules?

Well, your records do not seem to be proxied, so the firewall won’t work, you need to make sure the web-related records are set to :orange:. But once that is properly configured these addresses should be blocked.
