Always On VPN and VpnStrategy

NetMotion Mobility for DirectAccess Administrators – Split vs. Force Tunneling

Always On VPN supports a variety of VPN protocols for the user tunnel. Internet Key Exchange version 2 (IKEv2) and Secure Socket Tunneling Protocol (SSTP) are the most common. I wrote about the advantages and disadvantages of each in this post. To summarize, IKEv2 provides the highest security options but suffers from operational limitations. SSTP offers excellent security and is generally more reliable.

VpnStrategy

Always On VPN administrators must choose between IKEv2 and SSTP when configuring the Always On VPN user tunnel. Some administrators may prefer to use IKEv2 when available but then fall back to SSTP if it is not. To accomplish this requires editing the rasphone.pbk file and setting the value of VpnStrategy to 8, as described here.

Challenges

Unfortunately, setting the VpnStrategy value to 8 poses some challenges. Updating rasphone.pbk requires editing a text file on each endpoint post-deployment. Updating rasphone.pbk can be automated using the Update-Rasphone.ps1 script or Microsoft Intune proactive remediation.

Limitations

By default, Windows will overwrite the VpnStrategy setting in rasphone.pbk when fallback occurs. For example, setting VpnStrategy to prefer IKEv2 over SSTP will be reset to use SSTP first if a connection with IKEv2 fails. There’s a registry setting available that’s supposed to prevent this, but it doesn’t always work as expected.

Windows 11

There’s good news for administrators deploying Always On VPN on Windows 11. Microsoft recently introduced support for additional NativeProtocol types in XML. Specifically, VPN protocol preference can now be defined using the ProtocolList native protocol type. When using the ProtocolList native protocol type, each supported VPN protocol is listed in order of preference using the syntax shown below.

In addition, the RetryTimeInHours value defines the time Windows will try the last successful connection protocol. Setting this value to 0 overrides this and ensures the preferred protocol (the first protocol in the list) will always be attempted first.

SSTP Only

Previously the VPNv2CSP only supported IKEv2 or Automatic as values for the native protocol type. Windows 11 now supports SSTP as a native protocol type. Administrators configuring Always On VPN user tunnel connections using SSTP exclusively can now use this option.

Caveats

While the settings above are supported in both Windows 11 21H2 and 22H2, there are some known issues when enabling these settings. Specifically, when administrators define the ProtocolList value for the native protocol type, IKEv2 is always shown as the active protocol, even when an SSTP connection is established.

Also, if ProtocolList is used, the VPN connection cannot be managed using PowerShell. The VPN profile will not be displayed when running Get-VpnConnection at the time of this writing. Hopefully Microsoft will fix this soon.

Always On VPN at MMSMOA 2023

I’m excited to share that I’ve been invited to present at the popular Midwest Management Summit at Mall of America (MMSMOA) this year! The event takes place Monday, May 2, through Thursday, May 4, 2023.

Sessions

I will be delivering two talks at the event this year. One on Microsoft Always On VPN and Intune, the other on deploying certificate using Intune.

Always On VPN and Intune: Notes from the FieldTuesday, May 2 at 10:00 AM CDT

This session will cover all aspects of deploying and managing Always On VPN client configuration settings using Microsoft Intune.

Intune Certificate ManagementWednesday, May 3 at 10:00 AM CDT

This session will provide detailed configuration guidance and best practice recommendations for issuing on-premises enterprise PKI certificate using Microsoft Intune.

Attending MMS?

Will you be attending MMSMOA? Let’s connect! Drop in on my sessions, of course, but let’s plan to hang out! I will have copies of my book to give away too, so don’t miss out. Send me a note here or on Twitter, or just find me at the conference. Looking forward to seeing all of you soon!
