04/19/2024

This article shows you how to set up Private Link with Azure Virtual Desktop to privately connect to your remote resources. For more information about using Private Link with Azure Virtual Desktop, including limitations, see Azure Private Link with Azure Virtual Desktop.

Prerequisites

In order to use Private Link with Azure Virtual Desktop, you need the following things:

An existing host pool with session hosts, an application group, and workspace.
An existing virtual network and subnet you want to use for private endpoints.
The required Azure role-based access control permissions to create private endpoints.
If you're using the Remote Desktop client for Windows, you must use version 1.2.4066 or later to connect using a private endpoint.
If you want to use Azure CLI or Azure PowerShell locally, see Use Azure CLI and Azure PowerShell with Azure Virtual Desktop to make sure you have the desktopvirtualization Azure CLI extension or the Az.DesktopVirtualization PowerShell module installed. Alternatively, use the Azure Cloud Shell.
Azure PowerShell cmdlets for Azure Virtual Desktop that support Private Link are in preview. You'll need to download and install the preview version of the Az.DesktopVirtualization module to use these cmdlets, which have been added in version 5.0.0.

Enable Private Link with Azure Virtual Desktop on a subscription

To use Private Link with Azure Virtual Desktop, you need to re-register the Microsoft.DesktopVirtualization resource provider on each subscription you want to use Private Link with Azure Virtual Desktop.

Important

For Azure for US Government and Azure operated by 21Vianet, you also need to register the feature for each subscription.

Register Private Link with Azure Virtual Desktop (Azure for US Government and Azure operated by 21Vianet only)

To register the Azure Virtual Desktop Private Link feature:

Sign in to the Azure portal.
In the search bar, enter Subscriptions and select the matching service entry.
Select the name of your subscription, then in the Settings section, select Preview features.
Select the drop-down list for the filter Type and set it to Microsoft.DesktopVirtualization.
Select Azure Virtual Desktop Private Link, then select Register.

Re-register the resource provider

To re-register the Microsoft.DesktopVirtualization resource provider:

Sign in to the Azure portal.
In the search bar, enter Subscriptions and select the matching service entry.
Select the name of your subscription, then in the section Settings, select Resource providers.
Search for and select Microsoft.DesktopVirtualization, then select Re-register.
Verify that the status of Microsoft.DesktopVirtualization is Registered.

Create private endpoints

During the setup process, you create private endpoints to the following resources, depending on your scenario.

Both clients and session host VMs use private routes. You need the following private endpoints:

Purpose	Resource type	Target sub-resource	Endpoint quantity	IP address quantity
Connections to host pools	Microsoft.DesktopVirtualization/hostpools	connection	One per host pool	Four per endpoint
Feed download	Microsoft.DesktopVirtualization/workspaces	feed	One per workspace	Two per endpoint
Initial feed discovery	Microsoft.DesktopVirtualization/workspaces	global	Only one for all your Azure Virtual Desktop deployments	One per endpoint

Clients use public routes while session host VMs use private routes. You need the following private endpoints. Endpoints to workspaces aren't required.

Purpose	Resource type	Target sub-resource	Endpoint quantity	IP address quantity
Connections to host pools	Microsoft.DesktopVirtualization/hostpools	connection	One per host pool	Four per endpoint

Important

IP address allocations are subject to change as the demand for IP addresses increases. During capacity expansions, additional addresses are needed for private endpoints. It's important you consider potential address space exhaustion and ensure sufficient headroom for growth. For more information on determining the appropriate network configuration for private endpoints in either a hub or a spoke topology, see Decision tree for Private Link deployment.

Connections to host pools

To create a private endpoint for the connection sub-resource for connections to a host pool, select the relevant tab for your scenario and follow the steps.

Here's how to create a private endpoint for the connection sub-resource for connections to a host pool using the Azure portal.

Sign in to the Azure portal.
In the search bar, type Azure Virtual Desktop and select the matching service entry to go to the Azure Virtual Desktop overview.
Select Host pools, then select the name of the host pool for which you want to create a connection sub-resource.
From the host pool overview, select Networking, then Private endpoint connections, and finally New private endpoint.

On the Basics tab, complete the following information:

Parameter	Value/Description
Subscription	Select the subscription you want to create the private endpoint in from the drop-down list.
Resource group	This automatically defaults to the same resource group as your workspace for the private endpoint, but you can also select an alternative existing one from the drop-down list, or create a new one.
Name	Enter a name for the new private endpoint.
Network interface name	The network interface name fills in automatically based on the name you gave the private endpoint, but you can also specify a different name.
Region	This automatically defaults to the same Azure region as the workspace and is where the private endpoint is deployed. This must be the same region as your virtual network and session hosts.

Once you've completed this tab, select Next: Resource.

On the Resource tab, validate the values for Subscription, Resource type, and Resource, then for Target sub-resource, select connection. Once you've completed this tab, select Next: Virtual Network.

Here's how to create a private endpoint for the connection sub-resource used for connections to a host pool using the Az.Network and Az.DesktopVirtualization PowerShell modules.

Important

In the following examples, you'll need to change the <placeholder> values for your own.

Launch the Azure Cloud Shell in the Azure portal with the PowerShell terminal type, or run PowerShell on your local device.
1. If you're using Cloud Shell, make sure your Azure context is set to the subscription you want to use.
2. If you're using PowerShell locally, first Sign in with Azure PowerShell, then make sure your Azure context is set to the subscription you want to use.

Get the details of the virtual network and subnet you want to use for the private endpoint and store them in a variable by running the following commands:

# Get the subnet details for the virtual network
$subnet = (Get-AzVirtualNetwork -Name <VNetName> -ResourceGroupName <ResourceGroupName>).Subnets | ? Name -eq <SubnetName>

Create a Private Link service connection for a host pool with the connection sub-resource by running the following commands.

# Get the resource ID of the host pool
$hostPoolId = (Get-AzWvdHostPool -Name <HostPoolName> -ResourceGroupName <ResourceGroupName>).Id

# Create the service connection
$parameters = @{
    Name = '<ServiceConnectionName>'
    PrivateLinkServiceId = $hostPoolId
    GroupId = 'connection'
}

$serviceConnection = New-AzPrivateLinkServiceConnection @parameters

Finally, create the private endpoint by running the commands in one of the following examples.

To create a private endpoint with a dynamically allocated IP address:

# Specify the Azure region. This must be the same region as your virtual network and session hosts.
$location = '<Location>'

# Create the private endpoint
$parameters = @{
    Name = '<PrivateEndpointName>'
    ResourceGroupName = '<ResourceGroupName>'
    Location = $location
    Subnet = $subnet
    PrivateLinkServiceConnection = $serviceConnection
}

New-AzPrivateEndpoint @parameters

To create a private endpoint with statically allocated IP addresses:

# Specify the Azure region. This must be the same region as your virtual network and session hosts.

$ip1 = @{
    Name = 'ipconfig1'
    GroupId = 'connection'
    MemberName = 'broker'
    PrivateIPAddress = '<IPAddress>'
}

$ip2 = @{
    Name = 'ipconfig2'
    GroupId = 'connection'
    MemberName = 'diagnostics'
    PrivateIPAddress = '<IPAddress>'
}

$ip3 = @{
    Name = 'ipconfig3'
    GroupId = 'connection'
    MemberName = 'gateway-ring-map'
    PrivateIPAddress = '<IPAddress>'
}

$ip4 = @{
    Name = 'ipconfig4'
    GroupId = 'connection'
    MemberName = 'web'
    PrivateIPAddress = '<IPAddress>'
}

# Create the private endpoint IP configurations
$ipConfig1 = New-AzPrivateEndpointIpConfiguration @ip1
$ipConfig2 = New-AzPrivateEndpointIpConfiguration @ip2
$ipConfig3 = New-AzPrivateEndpointIpConfiguration @ip3
$ipConfig4 = New-AzPrivateEndpointIpConfiguration @ip4

# Create the private endpoint
$parameters = @{
    Name = '<PrivateEndpointName>'
    ResourceGroupName = '<ResourceGroupName>'
    Location = $location
    Subnet = $subnet
    PrivateLinkServiceConnection = $serviceConnection
    IpConfiguration = $ipConfig1, $ipConfig2, $ipConfig3, $ipConfig4
}

You need to a create private endpoint for the feed sub-resource for each workspace you want to use with Private Link.

Initial feed discovery

To create a private endpoint for the global sub-resource used for the initial feed discovery, select the relevant tab for your scenario and follow the steps.

Important

Only create one private endpoint for the global sub-resource for all your Azure Virtual Desktop deployments.
A private endpoint to the global sub-resource of any workspace controls the shared fully qualified domain name (FQDN) for initial feed discovery. This in turn enables feed discovery for all workspaces. Because the workspace connected to the private endpoint is so important, deleting it will cause all feed discovery processes to stop working. We recommend you create an unused placeholder workspace for the global sub-resource.

From the Azure Virtual Desktop overview, select Workspaces, then select the name of a workspace you want to use for the global sub-resource.
1. Optional: Instead, create a placeholder workspace to terminate the global endpoint by following the instructions to Create a workspace.
From the workspace overview, select Networking, then Private endpoint connections, and finally New private endpoint.

On the Basics tab, complete the following information:

Parameter	Value/Description
Subscription	Select the subscription you want to create the private endpoint in from the drop-down list.

    --group-id global \
    --ip-config $ip \
    --output table

Your output should be similar to the following. Check that the value for ProvisioningState is Succeeded.

CustomNetworkInterfaceName    Location    Name                  ProvisioningState    ResourceGroup
----------------------------  ----------  --------------------  -------------------  ---------------
                              uksouth     endpoint-global       Succeeded            privatelink

You need to configure DNS for your private endpoint to resolve the DNS name of the private endpoint in the virtual network. The private DNS zone name is privatelink-global.wvd.microsoft.com. For the steps to create and configure the private DNS zone with Azure CLI, see Configure the private DNS zone.

Closing public routes

Once you've created private endpoints, you can also control if traffic is allowed to come from public routes. You can control this at a granular level using Azure Virtual Desktop, or more broadly using a network security group (NSG) or Azure Firewall.

Control routes with Azure Virtual Desktop

With Azure Virtual Desktop, you can independently control public traffic for workspaces and host pools. Select the relevant tab for your scenario and follow the steps. You can't configure this in Azure CLI. You need to repeat these steps for each workspace and host pool you use with Private Link.

Portal
Azure PowerShell

Workspaces

From the Azure Virtual Desktop overview, select Workspaces, then select the name of the workspace to control public traffic.
From the host pool overview, select Networking, then select the Public access tab.

Select one of the following options:

Setting	Description
Enable public access from all networks	End users can access the feed over the public internet or the private endpoints.
Disable public access and use private access	End users can only access the feed over the private endpoints.

Select Save.

Host pools

From the Azure Virtual Desktop overview, select Host pools, then select the name of the host pool to control public traffic.
From the host pool overview, select Networking, then select the Public access tab.

Select one of the following options:

Setting	Description
Enable public access from all networks	End users can access the feed and session hosts securely over the public internet or the private endpoints.
Enable public access for end users, use private access for session hosts	End users can access the feed securely over the public internet but must use private endpoints to access session hosts.
Disable public access and use private access	End users can only access the feed and session hosts over the private endpoints.

Select Save.

Important

Azure PowerShell cmdlets for Azure Virtual Desktop that support Private Link are in preview. You'll need to download and install the preview version of the Az.DesktopVirtualization module to use these cmdlets, which have been added in version 5.0.0.

Workspaces

In the same PowerShell session, you can disable public access and use private access by running the following command:

$parameters = @{
    Name = '<WorkspaceName>'
    ResourceGroupName = '<ResourceGroupName>'
    PublicNetworkAccess = 'Disabled'
}

Update-AzWvdWorkspace @parameters

To enable public access from all networks, run the following command:

$parameters = @{
    Name = '<WorkspaceName>'
    ResourceGroupName = '<ResourceGroupName>'
    PublicNetworkAccess = 'Enabled'
}

Update-AzWvdWorkspace @parameters

Host pools

In the same PowerShell session, you can disable public access and use private access by running the following command:

$parameters = @{
    Name = '<HostPoolName>'
    ResourceGroupName = '<ResourceGroupName>'
    PublicNetworkAccess = 'Disabled'
}

Update-AzWvdHostPool @parameters

To enable public access from all networks, run the following command:

$parameters = @{
    Name = '<HostPoolName>'
    ResourceGroupName = '<ResourceGroupName>'
    PublicNetworkAccess = 'Enabled'
}

Update-AzWvdHostPool @parameters

To use public access for end users, but use private access for session hosts, run the following command:

$parameters = @{
    Name = '<HostPoolName>'
    ResourceGroupName = '<ResourceGroupName>'
    PublicNetworkAccess = 'EnabledForSessionHostsOnly'
}

Update-AzWvdHostPool @parameters

To use private access for end users, but use public access for session hosts, run the following command:

$parameters = @{
    Name = '<HostPoolName>'
    ResourceGroupName = '<ResourceGroupName>'
    PublicNetworkAccess = 'EnabledForClientsOnly'
}

Update-AzWvdHostPool @parameters

Important

Changing access for session hosts won't affect existing sessions. After you've changed a private endpoint to a host pool, you must restart the Remote Desktop Agent Loader (RDAgentBootLoader) service on each session host in the host pool. You also need to restart this service whenever you change a host pool's network configuration. Instead of restarting the service, you can restart each session host.

Block public routes with network security groups or Azure Firewall

If you're using network security groups or Azure Firewall to control connections from user client devices or your session hosts to the private endpoints, you can use the WindowsVirtualDesktop service tag to block traffic from the public internet. If you block public internet traffic using this service tag, all service traffic uses private routes only.

Caution

Make sure you don't block traffic between your private endpoints and the addresses in the required URL list.
Don't block certain ports from either the user client devices or your session hosts to the private endpoint for a host pool resource using the connection sub-resource. The entire TCP dynamic port range of 1 - 65535 to the private endpoint is needed because port mapping is used to all global gateways through the single private endpoint IP address corresponding to the connection sub-resource. If you restrict ports to the private endpoint, your users may not be able to connect successfully to Azure Virtual Desktop.

Validate Private Link with Azure Virtual Desktop

Once you've closed public routes, you should validate that Private Link with Azure Virtual Desktop is working. You can do this by checking the connection state of each private endpoint, the status of your session hosts, and testing your users can refresh and connect to their remote resources.

Check the connection state of each private endpoint

To check the connection state of each private endpoint, select the relevant tab for your scenario and follow the steps. You should repeat these steps for each workspace and host pool you use with Private Link.

Workspaces

From the Azure Virtual Desktop overview, select Workspaces, then select the name of the workspace for which you want to check the connection state.
From the workspace overview, select Networking, then Private endpoint connections.
For the private endpoint listed, check the Connection state is Approved.

Host pools

From the Azure Virtual Desktop overview, select Host pools, then select the name of the host pool for which you want to check the connection state.
From the host pool overview, select Networking, then Private endpoint connections.
For the private endpoint listed, check the Connection state is Approved.

Important

You need to use the preview version of the Az.DesktopVirtualization module to run the following commands. For more information and to download and install the preview module, see PowerShell Gallery.

Workspaces

In the same PowerShell session, run the following commands to check the connection state of a workspace:

(Get-AzWvdWorkspace -Name <WorkspaceName> -ResourceGroupName <ResourceGroupName).PrivateEndpointConnection | FL Name, PrivateLinkServiceConnectionStateStatus, PrivateLinkServiceConnectionStateDescription, PrivateLinkServiceConnectionStateActionsRequired

Your output should be similar to the following. Check that the value for PrivateLinkServiceConnectionStateStatus is Approved.

Name                                             : endpoint-ws01
PrivateLinkServiceConnectionStateStatus          : Approved
PrivateLinkServiceConnectionStateDescription     : Auto-approved
PrivateLinkServiceConnectionStateActionsRequired : None

Host pools

In the same PowerShell session, run the following commands to check the connection state of a host pool:

(Get-AzWvdHostPool -Name <HostPoolName> -ResourceGroupName <ResourceGroupName).PrivateEndpointConnection | FL Name, PrivateLinkServiceConnectionStateStatus, PrivateLinkServiceConnectionStateDescription, PrivateLinkServiceConnectionStateActionsRequired

Your output should be similar to the following. Check that the value for PrivateLinkServiceConnectionStateStatus is Approved.

Name                                             : endpoint-hp01
PrivateLinkServiceConnectionStateStatus          : Approved
PrivateLinkServiceConnectionStateDescription     : Auto-approved
PrivateLinkServiceConnectionStateActionsRequired : None

In the same CLI session, run the following commands to check the connection state of a workspace or a host pool:

az network private-endpoint show \
    --name <PrivateEndpointName> \
    --resource-group <ResourceGroupName> \
    --query "{name:name, privateLinkServiceConnectionStates:privateLinkServiceConnections[].privateLinkServiceConnectionState}"

Your output should be similar to the following. Check that the value for status is Approved.

{
  "name": "endpoint-ws01",
  "privateLinkServiceConnectionStates": [
    {
      "actionsRequired": "None",
      "description": "Auto-approved",
      "status": "Approved"
    }
  ]
}

Check the status of your session hosts

Check the status of your session hosts in Azure Virtual Desktop.
1. From the Azure Virtual Desktop overview, select Host pools, then select the name of the host pool.
2. In the Manage section, select Session hosts.
3. Review the list of session hosts and check their status is Available.

Check your users can connect

To test that your users can connect to their remote resources:

Use the Remote Desktop client and make sure you can subscribe to and refresh workspaces.
Finally, make sure your users can connect to a remote session.
