You can drag network and security components onto the design canvas to make their settings available for machine component configuration in the blueprint. After you have defined network and security settings for the machine, you can optionally associate settings from a load balancer component.
After you add an NSX network or security component to the canvas and define its available settings, you can open the network and security tabs of a vSphere machine component in the canvas and configure its settings.
The network and security component settings that you add to the blueprint design canvas are derived from your NSX configuration and require that you have installed the NSX plug-in and run data collection for the NSX inventory for vSphere clusters. Network and security components are specific to NSX and are available for use with vSphere machine components only. For information about configuring NSX, see NSX Administration Guide.
For example, you can drag an on-demand NAT network component onto the blueprint's design canvas to make it available for a vSphere machine component that is also present in the canvas.
