Would you consider fail2ban in this case?

  "Warning: Using an IP blacklist will stop trivial attacks but it relies on an additional daemon and successful logging (the partition containing /var can become full, especially if an attacker is pounding on the server). Additionally, if the attacker knows your IP address, they can send packets with a spoofed source header and get you locked out of the server. SSH keys provide an elegant solution to the problem of brute forcing without these problems." source: https://wiki.archlinux.org/index.php/Fail2ban https://wiki.archlinux.org/index.php/Fail2ban

      From memory, you can spoof UDP but not TCP. https://serverfault.com/a/153619/91708 https://serverfault.com/a/153619/91708
