How does the Digital Ocean Cloud Firewall block unwanted traffic when I specify an inbound droplet?
In Digital Ocean’s Cloud Firewall (https://www.digitalocean.com/docs/networking/firewalls/), it’s possible to set acceptable inputs to your droplet as opposed to IP addresses. How does the firewall block unwanted requests? Ie is DigitalOcean checking against the IP address of the server or is it something else?
