Hi, it is possible to manage the firewall from ISPConfig GUI? For example, now I get my PC banned for FTP by PureFTP - Fail2Ban. But I'm unable to whitelist my IP. I also buy documentation for ISPConfig, but sorry I had to say it is quite not useful. Thanks for the advice. I really missing more management in GUI.
No, there is no way to manage fail2ban in the gui, you will have to do that from the cli (/etc/fail2ban/jail.local).
