Fail2ban / intrusion detection settings have no effect

System admin module version: 17.0.2.36

Had to recently reinstall because of a hack. Problem I and other users described earlier is still here.

This is how Admin → System Admin → Intrusion Detection always looks like this:

No matter what I set there - it has no effect, and /etc/fail2ban/jail.local will always have
bantime = 0
findtime = 0
maxretry = 5

Debian 13 or 12 ?

It’s Debian 12

As workaround I have /etc/fail2ban/jail.d/misc.local where I override values:

[DEFAULT]
bantime=600
findtime=600
ignoreself = true
