That’s also possible to “roll your own”. I was considering this at my last place, but never got round to doing it.
The only hard bit is messaging between machines, but my plan was to send a message to the outside router so it could block the address at the perimeter.

One thought I had was to use syslog to send certain messages to the router’s syslog so fail2ban could pick them up and apply rules.
