I switched now to security/sshguard-pf.
It works perfectly and blocks also via pf.
Blocking is working there with:
table <sshguard> persist
block in log quick proto tcp from <sshguard> to any label "ssh
bruteforce" probability 85%
So I let 15% of the pakets through in the hope that will slow down this
brute force attacks and I can protect in this step other hosts.
Hopefully the attacker keeps then longer in my tarpit.
