In this quickstart, learn how to create a NAT gateway by using the Azure portal, Azure CLI, PowerShell, Bicep, ARM template and Terraform. The NAT Gateway service provides outbound connectivity for virtual machines in Azure.
Create a NAT gateway
Before you deploy the NAT gateway resource and the other resources, a resource group is required to contain the resources deployed. In the following steps, you create a resource group, NAT gateway resource, and a public IP address. You can use one or more public IP address resources, public IP prefixes, or both.
For information about public IP prefixes and a NAT gateway, see Manage NAT gateway.
In the search box at the top of the portal, enter NAT gateway. Select NAT gateways in the search results.
Select + Create.
In Create network address translation (NAT) gateway, enter or select this information in the Basics tab:

Note
Virtual machines in a virtual network with a bastion host don't need public IP addresses. Bastion provides the public IP, and the VMs use private IPs to communicate within the network. You can remove the public IPs from any VMs in bastion hosted virtual networks. For more information, see Dissociate a public IP address from an Azure VM.
Note
Azure provides a default outbound access IP for VMs that either aren't assigned a public IP address or are in the backend pool of an internal basic Azure load balancer. The default outbound access IP mechanism provides an outbound IP address that isn't configurable.
The default outbound access IP is disabled when one of the following events happens:
- A public IP address is assigned to the VM.
- The VM is placed in the backend pool of a standard load balancer, with or without outbound rules.
- An Azure NAT Gateway resource is assigned to the subnet of the VM.
VMs that you create by using virtual machine scale sets in flexible orchestration mode don't have default outbound access.
For more information about outbound connections in Azure, see Default outbound access in Azure and Use Source Network Address Translation (SNAT) for outbound connections.
Create a resource group
Create a resource group with New-AzResourceGroup. An Azure resource group is a logical container into which Azure resources are deployed and managed.
The following example creates a resource group named test-rg in the eastus2 location:
$rsg = @{
Name = 'test-rg'
Location = 'eastus2'
}
New-AzResourceGroup @rsg
Create the NAT gateway
In this section, create the NAT gateway and supporting resources.
## Create public IP address for NAT gateway ##
$ip = @{
Name = 'public-ip-nat'
ResourceGroupName = 'test-rg'
Location = 'eastus2'
Sku = 'Standard'
AllocationMethod = 'Static'
Zone = 1,2,3
}
$publicIP = New-AzPublicIpAddress @ip
## Create NAT gateway resource ##
$nat = @{
ResourceGroupName = 'test-rg'
Name = 'nat-gateway'
IdleTimeoutInMinutes = '10'
Sku = 'Standard'
Location = 'eastus2'

}
$natGateway = New-AzNatGateway @nat
## Create subnet config and associate NAT gateway to subnet##
$subnet = @{
Name = 'subnet-1'
AddressPrefix = '10.0.0.0/24'
NatGateway = $natGateway
}
$subnetConfig = New-AzVirtualNetworkSubnetConfig @subnet
## Create Azure Bastion subnet ##
$bastsubnet = @{
Name = 'AzureBastionSubnet'
AddressPrefix = '10.0.1.0/26'
}
$bastsubnetConfig = New-AzVirtualNetworkSubnetConfig @bastsubnet
## Create the virtual network ##
$net = @{
Name = 'vnet-1'
ResourceGroupName = 'test-rg'
Location = 'eastus2'
AddressPrefix = '10.0.0.0/16'
Subnet = $subnetConfig,$bastsubnetConfig
}
$vnet = New-AzVirtualNetwork @net
## Create public IP address for bastion host ##
$ip = @{
Name = 'public-ip'
ResourceGroupName = 'test-rg'
Location = 'eastus2'

An Azure Resource Manager template is a JavaScript Object Notation (JSON) file that defines the infrastructure and configuration for your project. The template uses declarative syntax. You describe your intended deployment without writing the sequence of programming commands to create the deployment.
If your environment meets the prerequisites and you're familiar with using ARM templates, select the Deploy to Azure button. The template opens in the Azure portal.
Review the template
The template used in this quickstart is from Azure Quickstart Templates.
This template is configured to create a:

Nine Azure resources are defined in the Bicep file:
Deploy the Bicep file
Save the Bicep file as main.bicep to your local computer.
Deploy the Bicep file using either Azure CLI or Azure PowerShell.
Azure CLI
az group create --name exampleRG --location eastus
az deployment group create --resource-group exampleRG --template-file main.bicep --parameters adminusername=<admin-name>
PowerShell
New-AzResourceGroup -Name exampleRG -Location eastus
New-AzResourceGroupDeployment -ResourceGroupName exampleRG -TemplateFile ./main.bicep -adminusername "<admin-name>"
Note
Replace <admin-name> with the administrator username for the virtual machine. You'll also be prompted to enter adminpassword.
When the deployment finishes, you should see a message indicating the deployment succeeded.
Review deployed resources
Use the Azure portal, Azure CLI, or Azure PowerShell to list the deployed resources in the resource group.
Azure CLI
az resource list --resource-group exampleRG
PowerShell
Get-AzResource -ResourceGroupName exampleRG
In this section, you test the NAT gateway. You first discover the public IP of the NAT gateway. You then connect to the test virtual machine and verify the outbound connection through the NAT gateway.
