The Firewall tab lets you configure rules to control incoming traffic by protocol, port range, and source IPs, securing your datacenter from unwanted connections.

By default, the firewall allows all traffic. Once you add the first rule, it switches to a default-deny model, blocking all traffic unless explicitly permitted.

It means that after adding the first firewall rule, all incoming traffic is blocked unless it matches a rule you’ve configured.

Rules are created by specifying the protocol (TCP, UDP, ICMP), port range, and source IP addresses or ranges that are allowed.

Yes. Firewall rules allow you to specify individual IP addresses or ranges to tightly control which sources can access your datacenter.

You can define rules for common protocols like TCP, UDP, and ICMP, giving you flexibility over how traffic is handled.

It creates a secure perimeter around your server, ensuring that only authorized traffic reaches your datacenter.

If no rules are defined, the firewall returns to its default state, allowing all incoming traffic.

You can tailor access precisely by combining protocol selection, port ranges, and source IP filters for detailed control.

You should configure rules whenever you want to restrict access to your datacenter, protect sensitive services, or enforce strict security policies.
