Hello Onno,

This sounds like fail2ban.

This depends on  which firewall software you use (which is for permanent
configuration, not temporary like fail2ban).

This is totally unrelated to systemd, so please rather consult the
documentation or ask on the mailing lists/forum of  your firewall software.
