Deploying Always On VPN with Intune using Custom ProfileXML

Deploying Always On VPN with Intune using Custom ProfileXMLWhen deploying Windows 10 Always On VPN using Microsoft Intune, administrators have two choices for configuring VPN profiles. They can use the native Intune user interface (UI) or create and upload a custom ProfileXML. The method chosen will depend on which features and settings are required.

Microsoft Intune

Intune has an intuitive user interface (UI) that can be used to configure and deploy Always On VPN profiles to Windows 10 clients. Guidance for using the UI to deploy Windows 10 Always On VPN with Microsoft Intune can be found here. However, Intune does not expose all Always On VPN settings to the administrator, which can be problematic.

Missing from Intune

At the time of this writing, the following Always On VPN settings cannot be configured natively using the Intune UI.

To implement any of the above features or settings the administrator must create and upload a custom ProfileXML.

ProfileXML

ProfileXML is a node within the VPNv2 Configuration Service Provider (CSP). When configuring Always On VPN using the Intune UI, each setting is configured individually. By contrast, the ProfileXML node includes all Always On VPN settings in a single configuration file. It can be deployed using Intune or PowerShell. Sample ProfileXML files for both user and device tunnels can be downloaded from my GitHub repository.

ProfileXML and Intune

I’ve already documented how to deploy an Always On VPN device tunnel configuration using Intune, so this post will focus on deploying the user tunnel using ProfileXML.

Once ProfileXML has been configured, open the Intune management console and follow the steps below to deploy it using Intune.

Create Profile

1. In the navigation pane click Device Configuration.
2. Click Profiles.
3. Click Create Profile.
4. Enter a descriptive name for the new VPN profile.
5. Select Windows 10 and later from the Platform drop-down list.
6. Select Custom from the Profile type drop-down list.

Custom OMA-URI Settings

1. In the Custom OMA-URI Settings blade click Add.
2. Enter a descriptive name in the Name field (this name will appear in the Windows UI on the client).
3. Enter ./User/Vendor/MSFT/VPNv2/Always%20On%20VPN/ProfileXML in the OMA-URI field. I’ve used Always On VPN as an example here, but you can use any text you like. If it includes spaces they must be escaped using %20, as shown here. Also, don’t forget to include the leading “.“.
4. Select String (XML file) from the Data type drop-down list.
5. Click the folder next to the Select a file field and select your ProfileXML file.
6. Click Ok.

Deploying Always On VPN with Intune using Custom ProfileXML

Important Note: The File contents window must show the contents of your ProfileXML. If the contents are unreadable the XML file contains encoding that will not work. If this happens, copy the contents of your ProfileXML to another new text file and upload again.

Assign Profile

Follow the steps below to assign the Always On VPN profile to the appropriate user group.

1. Click Assignments.
2. Click Select groups to include.
3. Select the group that includes the target users.
4. Click Select.
5. Click Save.

Always On VPN Device Tunnel Configuration using Intune

Always On VPN Device Tunnel Configuration using IntuneA while back I described in detail how to configure a Windows 10 Always On VPN device tunnel connection using PowerShell. While using PowerShell is fine for local testing, it obviously doesn’t scale well. In theory you could deploy the PowerShell script and XML file using System Center Configuration Manager (SCCM), but using Microsoft Intune is the recommended and preferred deployment method. However, as of this writing Intune does not support device tunnel configuration natively. The administrator must create a ProfileXML manually and use Intune to deploy it.

Device Tunnel Prerequisites

I outlined the Always On VPN device tunnel prerequisites in my previous post here. To summarize, the client must be running Windows 10 Enterprise edition and be domain-joined. It must also have a certificate issued by the internal PKI with the Client Authentication EKU in the local computer certificate store.

ProfileXML

To begin, create a ProfileXML for the device tunnel that includes the required configuration settings and parameters for your deployment. You can find a sample Windows 10 Always On VPN device tunnel ProfileXML here.

Note: Be sure to define a custom IPsec policy in ProfileXML for the device tunnel. The default security settings for the IKEv2 protocol (required for the device tunnel) are quite poor. Details here.

Intune Deployment

Open the Intune management console and follow the steps below to deploy an Always On VPN device tunnel using Microsoft Intune.

Create Profile

1. Navigate to the Intune portal.
2. Click Device configuration.
3. Click Profiles.
4. Click Create profile.

Define Profile Settings

1. Enter a name for the VPN connection in the Name field.
2. Enter a description for the VPN connection in the Description field (optional).
3. Select Windows 10 and later from the Platform drop-down list.
4. Select Custom from the Profile type drop-down list.

Define Custom OMA-URI Settings

1. On the Custom OMA-URI Settings blade click Add.
2. Enter a name for the device tunnel in the Name field.
3. Enter a description for the VPN connection in the Description field (optional).
4. Enter the URI for the device tunnel in the OMA-URI field using the following syntax. If the profile name includes spaces they must be escaped, as shown here.

./Device/Vendor/MSFT/VPNv2/Example%20Profile%Name/ProfileXML

5. Select String (XML file) from the Data Type drop-down list.
6. Click the folder next to the Select a file field and chose the ProfileXML file created previously.
7. Click Ok twice and then click Create.

Deploying Windows 10 Always On VPN with Microsoft Intune

Deploying Windows 10 Always On VPN with Microsoft IntuneWindows 10 Always On VPN is the replacement for Microsoft’s popular DirectAccess remote access solution. It provides the same seamless, transparent, always on remote connectivity as DirectAccess. Where DirectAccess relied heavily on classic on-premises infrastructure such as Active Directory and Group Policy, Always On VPN is infrastructure independent and is designed to be provisioned and managed using a Mobile Device Management (MDM) platform such as Microsoft Intune.

Intune and Always On VPN

Until recently, provisioning Windows 10 Always On VPN connections involved manually creating a ProfileXML and uploading to Intune using a custom profile. This has proven to be challenging for many, as the process is unintuitive and error prone.

A recent Intune update now allows administrators to create a basic Windows 10 Always On VPN deployment. Although it still has its limitations, it will go a long way to making the adoption of Always On VPN easier.

Prerequisites

Certificates must first be provisioned to all clients before deploying Windows 10 Always On VPN using Intune. In addition, if using a third-party VPN client, the VPN plug-in software must be installed prior to deploying the VPN profile.

Test VPN Connection

It is recommended that a test VPN connection be created on a client machine locally before deploying an Always On VPN profile using Intune. This allows the administrator to test connectivity and validate Extensible Authentication Protocol (EAP) settings. Once complete, run the following PowerShell commands to extract the EAP configuration settings to a file for later publishing with Intune.

$Vpn = Get-VpnConnection -Name [Test VPN connection name]
$Xml = $Vpn.EapConfigXmlStream.InnerXml | Out-File .\eapconfig.xml -Encoding ASCII

  4. Enter a description and provide the FQDN for any additional VPN servers, as required.
  5. From the Connection type drop-down list choose the preferred connection type.
  6. In the Always On section click Enable.
  7. Select Enable to Remember credentials at each logon (optional).
  8. Click Select a certificate.
  9. Choose a client authentication certificate and click Ok.
  10. Paste the contents of eapconfig.xml (saved previously) in the EAP Xml field.
  11. Click Ok.

Limitations

Although the ability to provision Always On VPN using Microsoft Intune without using a custom profile is welcome, it is not without its limitations. At the time of this writing, only Always On VPN user profiles can be configured. A device tunnel, which is optional, must be configured manually using a custom profile. In addition, the Intune user interface lacks the ability to define settings for the following parameters:

  • Custom IKEv2 cryptography policy
  • Exclusion routes
  • Lockdown mode

To make changes to the default settings for any of the above parameters, a ProfileXML must be created manually and provisioned with Intune using a custom policy.
