Firewall configuration
4 min read
A baseline firewall is configured automatically when your VPS is created.
Default rules
New instances are provisioned with ufw set to deny all incoming traffic by default, except SSH (port 22), HTTP (80), and HTTPS (443), which are explicitly allowed. Outgoing traffic is unrestricted.
Changing the rules
These are standard ufw rules on your own server — SSH in and use ufw allow / ufw deny to open or close additional ports as your app needs.
