+## Chain virtual machine to Gateway Load Balancer
+
+Alternatively, you can chain a VM's NIC IP configuration to the gateway load balancer. 
+
+You'll add the gateway load balancer's frontend to an existing VM's NIC IP configuration.
+
+Use [Set-AzNetworkInterfaceIpConfig](/powershell/module/az.network/set-aznetworkinterfaceipconfig) to chain the gateway load balancer frontend to your existing VM's NIC IP configuration.

 ## Clean up resources
 
 When no longer needed, you can use the [Remove-AzResourceGroup](/powershell/module/az.resources/remove-azresourcegroup) command to remove the resource group, load balancer, and the remaining resources.
