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 ProfileXML Editing and Formatting with Visual Studio Code

Always On VPN ProfileXML Editing and Formatting with Visual Studio CodeWindows 10 Always On VPN is designed to be implemented and managed using a Mobile Device Management (MDM) platform such as Microsoft Intune. With Intune specifically, there is an option to configure an Always On VPN profile in the UI. However, it provides only limited support and does not include all settings and options required for many deployments. Crucially, IKEv2 advanced security settings cannot be configured using the Intune portal. Also, there is currently no option for configuring a device tunnel with Intune. In these scenarios the administrator must manually create a ProfileXML file and provision it using Intune, System Center Configuration Manager (SCCM), or PowerShell.

ProfileXML

ProfileXML includes all settings that define the Always On VPN connection. The options and settings available are documented in the VPNv2 Configuration Service Provider (CSP) reference on Microsoft’s web site. ProfileXML is formatted using elements and settings within those elements. The formatting and syntax are critical to ensuring proper operation. Any error in syntax or formatting can result in an error, such as those described here.

XML Readability

Formatting is also important for readability, which is often helpful when reviewing configuration settings or troubleshooting syntax errors. For example, an element may be defined correctly but may be nested wrong. Often XML files are created with all text being left-justified, or with everything on a single line, making the content difficult to read. Using a file editor that recognizes XML files can be beneficial.

Visual Studio Code

To create, edit, and review ProfileXML it is recommended that a proper editing tool be used. I recommend using Microsoft’s Visual Studio Code. It is free, and it is especially helpful when editing XML files. Visual Studio Code can be downloaded here.

XML Tools VS Code Plug-In

To further enhance Visual Studio Code’s XML editing and formatting capabilities I recommend installing the XML Tools plug-in. This tool extends the native features of VS code for handling XML files. One important thing it adds is a formatting feature that will make your ProfileXML much easier to manage. The XML Tools plug-in for VS Code can be downloaded here.

XML Formatting

Once the XML Tools plug-in for VS code has been installed, formatting XML for readability is straightforward. Simply right-click anywhere in the document and choose Format Document.

Always On VPN ProfileXML Editing and Formatting with Visual Studio CodeOnce complete, the XML document will be formatted with proper indenting and nesting of elements, as shown here.

Always On VPN ProfileXML Editing and Formatting with Visual Studio CodeSummary

Formatting and syntax must be strictly adhered to when creating a ProfileXML file for Windows 10 Always On VPN. Using Visual Studio Code with the XML Tools plug-in allow the administrator to create and edit XML with proper formatting, which greatly improves readability and allows for streamlined configuration review and troubleshooting.
