A firewall should allow the traffic your server needs and quietly refuse the rest. To configure VPS firewall rules safely, start with the services that must remain reachable, especially SSH, then add web and application ports one at a time. Do not begin by blocking everything from the only terminal session you have open. That is how a calm maintenance task becomes a console-recovery task.

For most Linux VPS deployments, the practical goal is simple: deny unsolicited inbound traffic by default, allow required outbound traffic, and create narrow inbound rules for trusted users and services. This reduces attack surface without making routine administration difficult.
