What is a NAT server?
A NAT server has no dedicated public IP — only a few ports mapped by the provider (e.g. SSH 22). The panel cannot SSH into its private IP directly.
Solution: Tunneling
1. Generate an install command for this server in the panel's "Tunneling".
2. Run the command on the target server to install the Agent (zero footprint).
3. The Agent dials back to the panel to establish an encrypted tunnel, after which you can manage it like a normal server.
Port Tunneling
To run websites/databases on a NAT server, use "Port Tunneling" to map internal ports to the panel server's public ports.
