Hi there,
Setting up a DigitalOcean Cloud Firewall is pretty straightforward and doesn’t require installing anything on your Droplet.
At a high level, you can do it directly from the control panel:
-
Go to Networking → Firewalls
-
Click Create Firewall
-
Give it a name
-
Add your inbound rules (for example: SSH on port 22, HTTP 80, HTTPS 443)
-
Add outbound rules (usually allow all by default)
-
Attach it to your Droplet (or use tags)
Once applied, the firewall will block all traffic that isn’t explicitly allowed by your rules:

A couple of quick tips:
-
Start with allowing SSH (port 22), otherwise you might lock yourself out
-
Only open the ports you actually need
-
You can restrict access by IP instead of allowing everything
Overall, it’s one of the easier cloud firewalls to set up, and it’s free to use with your Droplets.
