I'm having issues setting up the SSH block password guessing feature properly.
In Definitions & Users -> Authentication Services -> Advanced -> Block password guessing I have set attempts to 3, block for 1800 secs, enabled drop packets and ticked SSH access in Facilities. The list of "Never block networks" is empty.
When I try false logins from another (non-local) remote server via SSH, I'm never getting blocked. I got 5 emails from UTM about a failed SSH login (5 is the limit), but I don't get the email stating that the IP has been blocked for 1800 seconds.
The SSH log shows that the device sees the failed logins:

The weird thing is that from time to time I get emails about some IP being blocked. I just don't seem to be able to block myself...
Thanks for the help.
