 When you create an internal load balancer, a virtual network is configured as the network for the load balancer. Before you deploy VMs and test your load balancer, create the supporting virtual network resources.
 
-Create a virtual network for the backend virtual machines
+- Create a public IP for the NAT gateway
 
-Create a network security group to define inbound connections to your virtual network

+Use [New-AzPublicIpAddress](/powershell/module/az.network/new-azpublicipaddress) to create a public IP address for the NAT gateway.

+```azurepowershell-interactive
+## Create public IP address for NAT gateway and place IP in variable ##

+    Zone = 1,2,3

+To create a zonal public IP address in zone 1, use the following command:
