Thank you. fail2ban is another approach (like sshguard), but it still
suffers from this shortage.
I do not want to hack my system, so I migrated to bare iptables:
``netfilter-persistent`` with  ``ipset-persistent`` and
``iptables-persistent`` plugins (as Debian people would do) until this
issue gets fixed.
