Problem with Fastpanel
Hello everyone, I need help with Fastpanel:
If I add any IP address to the firewall, the server completely crashes, rebooting does not help, only a rebuild at the hosting provider level (Hetzner) brings it back to life, after rolling back to the last backup.

I need to understand what the problem is and fix it, so that I can add IPs to the blacklist in the future without fearing that my server will crash...

Hello!
I can help you with the issue in FastPanel and configure the firewall so that IP blocking does not take the server down.
• I will conduct an audit of the current iptables/FastPanel configuration.
• I will fix the logic of adding rules so that SSH and panel ports remain accessible.
• I will set up a secure IP blocking process with the ability to roll back.
• Testing the rules before applying them to avoid server crashes.

Не проще написать в поддержку fastpanel ?

логи после апдейта черного списка смотрели? как себя ведет после этого сам сервер?

Як альтернативний варіант - поставити fail2ban, якщо вам не суттєво, як блокувати ip адреси (через веб-інтерфейс або через консоль сервера)
