• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Question How to deny all IPs in Plesk Firewall except certain IPs (e.g. Cloudflare IPs)?

BernieG

Basic Pleskian
Hi,

My website is going through a DDoS attack and now I'm trying to set up my website to use Cloudflare. I set up my website already through Cloudflare but now I'm trying to block any direct access to my server/website IP address since the hackers can still do DDoS attack using my IP address.

Please see screenshot image like below, I set up this configuration on my Plesk Firewall, however, I can still access my website if I use the IP address; why isn't Plesk blocking my access? Since I can still access my website via the IP address the DDoS attacks are still happening.


Should I block all IPs using .htaccess file instead? I would think the Plesk Firewall would be better option to use but it doesn't seem to be blocking all incoming traffic.

Thank you!
