How to remove the public IP address of a Mac mini

After enabling Virtual Private Cloud (VPC) on your Mac mini, you can enhance the security of your server by further restricting external access. This guide walks you through a series of steps to ensure that your Mac Mini is isolated from unauthorized access while maintaining necessary connectivity for management and maintenance.

By following these instructions, you will learn how to create a secure environment that uses Private Networks and an SSH Bastion to protect your machine from being reachable on the public Internet, while maintaining outgoing connectivity from the Mac mini.

Disabling DHCP on the public interface and removing the public IP addressLink to this anchor

Once you have verified that your Mac mini is reachable through the Bastion, you can proceed with disabling DHCP on your Mac’s main network interface (en0) and removing its public address. Your Mac mini is now fully isolated from the public internet, and any further external access will have to occur from a resource inside the Private Network or through the Bastion.
