I want to know how to block IP addresses via Digitalocean?

Actually, I want to block all bot IPs from visiting my webpage. Also want to block particular IP sets.


18 months later and the DO firewall still doesn’t support deny rules, only permit.

You can then block a specific IP address by running:

  1. sudo ufw deny from XXX.XXX.XX.XX
