Setting up the firewall
Allow only the connections you need.
The firewall blocks any incoming connection you haven't explicitly allowed. Each rule sets the direction, protocol, port and allowed addresses.
- Open the Firewall tab.
- Use the presets (SSH, Web, RDP and others) or add your own rule.
- Click Save.
Don't block your own access port (22 for SSH, 3389 for RDP) or you'll lock yourself out. If it happens, use the console or turn the firewall off from the panel.
Limiting admin access to your own IP address greatly reduces break-in attempts.
