Disable network policies for private endpoints

  • 2 minutes to read

Network policies like network security groups (NSG) are not supported for private endpoints. In order to deploy a Private Endpoint on a given subnet, an explicit disable setting is required on that subnet. This setting is only applicable for the Private Endpoint. For other resources in the subnet, access is controlled based on Network Security Groups (NSG) security rules definition.

When using the portal to create a private endpoint, this setting is automatically disabled as part of the create process. Deployment using other clients requires an additional step to change this setting. You can disable the setting using cloud shell from the Azure portal, or local installations of Azure PowerShell, Azure CLI, or use Azure Resource Manager templates.

The following examples describe how to disable PrivateEndpointNetworkPolicies for a virtual network named myVirtualNetwork with a default subnet hosted in a resource group named myResourceGroup.

Using Azure PowerShell

This section describes how to disable subnet private endpoint policies using Azure PowerShell.

$virtualNetwork= Get-AzVirtualNetwork `
  -Name "myVirtualNetwork" ` 
  -ResourceGroupName "myResourceGroup"  
   
($virtualNetwork | Select -ExpandProperty subnets | Where-Object  {$_.Name -eq 'default'} ).PrivateEndpointNetworkPolicies = "Disabled" 
 
$virtualNetwork | Set-AzVirtualNetwork

Using Azure CLI

This section describes how to disable subnet private endpoint policies using Azure CLI.

az network vnet subnet update \ 
  --name default \ 
  --resource-group myResourceGroup \ 
  --vnet-name myVirtualNetwork \ 
  --disable-private-endpoint-network-policies true

Using a template

This section describes how to disable subnet private endpoint policies using Azure Resource Manager Template.

{ 
          "name": "myVirtualNetwork", 
          "type": "Microsoft.Network/virtualNetworks", 
          "apiVersion": "2019-04-01", 
          "location": "WestUS", 
          "properties": { 
                "addressSpace": { 
                     "addressPrefixes": [ 
                          "10.0.0.0/16" 
                        ] 
                  }, 
                  "subnets": [ 
                         { 
                                "name": "default", 
                                "properties": { 
                                    "addressPrefix": "10.0.0.0/24", 
                                    "privateEndpointNetworkPolicies": "Disabled" 
                                 } 
                         } 
                  ] 
          } 
}
