Firewalls How-Tos

DigitalOcean Cloud Firewalls are a network-based, stateful firewall service for Droplets provided at no additional cost. Cloud firewalls block all traffic that isn’t expressly permitted by a rule.

Getting Started

How to Create Firewalls

Create a cloud firewall to restrict network traffic to and from specified Droplets.

How to Configure Firewall Rules

Create, modify, or delete firewall rules to restrict Droplets’ inbound and outbound traffic based on ports, sources, and destinations.

How to Add and Remove Droplets from Firewalls

Add Droplets to a firewall by name or by tag to apply the firewall’s rules.

How to Destroy Firewalls
