# Firewall

## Firewall Configuration

The Firewall setting lets you define security rules for incoming and outgoing network traffic to your VM. Allow or deny access to specific IP addresses, ports, or protocols.

- Go to VM Settings → Firewall.
- Click Manage to change firewall configurations for the network.

Example use case: block all traffic except SSH (port 22) and web traffic (ports 80/443).
