When Always On VPN Isn’t

Microsoft Always On VPN is a beautiful thing. VPN profiles are assigned to the user (and, optionally, their device). When users power up their device and log on, they are automatically connected to the corporate network and can access all the applications and data they need on-premises. Until recently, though, end users could disconnect the VPN. Why they would do this is beyond comprehension, but sadly, it happens all too often. When it does, it presents a problem for Always On VPN administrators because they must now rely on the user to re-enable this feature. And until they do, they often suffer productivity loss, and their devices may fall out of compliance.

Connect Automatically

When an Always On VPN profile is provisioned to a user (or a device), the VPN profile has the option to ‘Connect automatically’ enabled by default. Unfortunately, this setting is cleared if a user terminates the VPN.

This setting will remain cleared until the user rechecks the box to enable it. Until then, the VPN will no longer connect automatically.

Workarounds

Instead of relying on the grace of the end user to restore Always On functionality, administrators have a few options to correct this problem programmatically.

Intune Remediation

Administrators can use Intune Remediations to deploy a set of detection and remediation scripts I’ve published to update this setting. Now, administrators can enforce ‘Always On’ VPN connections with the assurance that if the user turns off this feature, it will be quickly re-enabled.

Remediate-AutoTriggerDisabledProfile.ps1

SCCM

You can find a standalone version of this script here if you use System Center Configuration Manager (SCCM) or another systems management solution to manage your endpoints.

Clear-AutoTriggerDisabledProfile.ps1

AovpnTools

In addition, you will find the Clear-AutoTriggerDisabledProfile function is included in my AOVPNTools PowerShell module, which can be installed from the PowerShell gallery.

Install-Module -Name AOVPNTools -Force

Disable Disconnect Button

To avoid this pain in the future, Always On VPN administrators can prevent users from disconnecting the VPN using the UI by leveraging the DisableDisconnectButton option in ProfileXML. This setting is supported for both user and device tunnels on Windows 11 and later devices.

Always On VPN CSP Updates

Always On VPN DNS Registration Update Available

Administrators can deploy Always On VPN client configuration settings in several ways. The simplest method is to use the native Microsoft Intune UI and the VPN device configuration profile template. Optionally, administrators can create an XML file that can be deployed with Intune using the Custom template. In addition, the XML file can be deployed using PowerShell, either interactively or with System Center Configuration Manager (SCCM). Administrators can also deploy the XML file using PowerShell via Active Directory group policy startup script or another software provisioning platform.

Custom XML

While using the native Intune VPN device configuration template to deploy and manage Always On VPN client configuration settings is easy and convenient, it lacks support for many crucial configuration settings. Deploying Always On VPN client settings using the Custom template is helpful to overcome these limitations as it enables additional configuration settings not exposed in the Intune VPN template.

VPNv2CSP

The VPNv2 Configuration Service Provider (CSP) is the interface used by Intune to deploy Always On VPN client configuration settings to the endpoint. The WMI-to-CSP bridge enables settings deployment using PowerShell. In either scenario, administrators must create an XML file that includes the settings used for the Always On VPN profile. A reference for all supported settings in the VPNv2 CSP can be found here.

New Settings

Microsoft recently introduced some new settings in the VPNv2 CSP. Beginning with Windows 11 22H2, administrators can disable the disconnect button and prevent access to the advanced settings menu for device and user tunnels in the Windows UI by adding the following entries in the XML configuration file.

<DisableDisconnectButton>true</DisableDisconnectButton>

<DisableAdvancedOptionsEditButton>true
</DisableAdvancedOptionsEditButton>

Additional Updates

Microsoft also added options to define encryption settings, disable IKEv2 fragmentation support, update IPv4 and IPv6 interface metrics, adjust IKEv2 network outage time, and disable the use of RAS credentials in XML for device and user tunnels. These new options eliminate the need to use Intune Proactive Remediation to adjust these VPN client configuration settings post-deployment.

Unfortunately, these settings are not supported in any current release of Windows 10 or 11 today. However, they are available in the latest Windows Insider build (development channel) if you want to test them. I’ve provided example settings below. These settings will be supported in a public release of Windows in the future.

<DataEncryption>Max</DataEncryption>
<DisableIKEv2Fragmentation>true</DisableIKEv2Fragmentation>
<IPv4InterfaceMetric>3</IPv4InterfaceMetric>
<IPv6InterfaceMetric>3</IPv6InterfaceMetric>
<NetworkOutageTime>0</NetworkOutageTime>
<UseRasCredentials>false</UseRasCredentials>

Note: At the time of this writing, the VPNv2 CSP indicates these settings apply to Windows 11 21H2 and later. That is incorrect. Microsoft is aware of the issue and will hopefully correct it soon.

Intune Support

At some point, Microsoft may add these features to the Intune VPN device configuration template. However, XML with the Custom template is the only way to enable these new settings today.

Always On VPN DPC with Intune

In the past, I’ve written about PowerON Platforms’ Always On VPN Dynamic Profile Configurator (DPC), a software solution administrators can use to provision and manage Always On VPN client configuration settings using Active Directory and group policy. In addition to streamlining the deployment and management of Always On VPN client settings, DPC has many advanced features and capabilities to ensure optimal security, performance, and connection reliability.

Optimizations

Many settings required to fine-tune and optimize Always On VPN connections are not exposed in the Intune UI or XML. They must be configured by manipulating configuration files, setting registry keys, and running PowerShell commands. Much of this can be automated using Intune Proactive Remediation, but it is far from ideal. Administrators must configure Always On VPN using one method, then deploy optimizations using another. In addition, Proactive Remediation suffers from timing issues where some settings are not applied immediately, resulting in degraded or inoperable VPN connections until changes take effect.

Always On VPN DPC

Always On VPN DPC allows administrators to configure many advanced settings quickly and conveniently using the familiar Group Policy Management console (gpmc.msc). DPC dramatically reduces the administrative burden associated with Always On VPN client management. In addition, DPC enables many of these options by default, ensuring optimal security and reliable operation. Also, DPC immediately implements all configuration settings, eliminating the need to reboot to apply configuration changes.

Intune and ADMX

Historically, Always On VPN DPC could only be used when managing endpoints exclusively with Active Directory group policy. However, DPC can now be used with Microsoft Endpoint Manager/Intune thanks to a new feature that allows administrators to import custom ADMX and ADML administrative templates to Microsoft Endpoint Manager (MEM).

Note: This feature is in public preview at the time of this writing.

DPC and Intune

The combination of DPC and Intune brings with it many advantages. Using DPC with Microsoft Endpoint Manager/Intune offers administrators simplified deployment and many advanced features provided by Always On VPN DPC. In addition, customers who have deployed DPC on-premises can now migrate seamlessly to Microsoft Endpoint Manager/Intune management without giving up DPC’s valuable features.
