 ## Create an AKS cluster with a Managed NAT Gateway
 
-To create an AKS cluster with a new Managed NAT Gateway, use `--outbound-type managedNATGateway`, `--nat-gateway-managed-outbound-ip-count`, and `--nat-gateway-idle-timeout` when running `az aks create`. The following example creates a *myResourceGroup* resource group, then creates a *natCluster* AKS cluster in *myResourceGroup* with a Managed NAT Gateway, two outbound IPs, and an idle timeout of 30 seconds.

If you want the NAT gateway to be able to operate out of availability zones, specify the zones using `--zones`.
