Hi @uniqf0x,
Thank you for your feedback, and I’m really sorry to hear about the trouble you experienced with your Cloudflare setup.
When a server’s origin IP gets blocked, it usually happens because the firewall is receiving internal server requests (or loopback requests) that trigger a security rule, and the server’s IP hasn’t been explicitly excluded from the blocking engine.
To securely connect Advanced IP Blocker with Cloudflare without locking yourself out, here is the recommended configuration:
1. Whitelist your Origin IP: Go to Advanced IP Blocker > Settings > IP Management and add your server’s Origin IP (both IPv4 and IPv6) to the Whitelist. This guarantees the firewall will never push a block rule against your own server.
2. Trust Cloudflare Networks: Ensure Cloudflare IPs are properly resolved. In the settings, under Trusted Proxies, you can quickly trust all Cloudflare traffic by adding their ASNs: AS13335 AS209242
3. Auto-Whitelist Admins (For Dynamic IPs): If your personal IP changes frequently, navigate to Login & User Protection > Advanced Login Protection and enable Auto-Whitelist Admins. This ensures that as long as you can log into your WordPress dashboard, your current IP will never be blocked by the Cloudflare integration.
The Cloudflare API integration is a very powerful feature, but it does require telling the plugin which IPs are “friendly” to avoid self-blocking loops.
I hope this helps you configure it safely! If this resolves your issue, I would really appreciate it if you could reconsider your rating. If you need any further assistance setting this up, please feel free to open a thread in the support forum and I’ll gladly help you out personally.
Best regards,
