Within the Connection entry add the gateway credentials which will be the exporting gateway - and ensure the Data set name "Hardware" defined in the Exporting Gateway matches the definition in the Importing gateway.

The Prefix field allows you to add a prefix to the netprobe and managed entity names.
If you chose not to prefix the imported data in the gateway, it will appear native along the local managed entities. Built-in commands will not be available on imported datasets.
