Always On VPN connections include two types of tunnels:. Device tunnel connects to specified VPN servers before users log on to the device. Pre-login connectivity scenarios and device management purposes use device tunnel. User tunnel connects only after a user logs on to the device. User tunnel allows users to access organization resources through VPN servers. Unlike user tunnelwhich only connects after a user logs on to the device or machine, device tunnel allows the VPN to establish connectivity before the user logs on.

Both device tunnel and user tunnel operate independently with their VPN profiles, can be connected at the same time, and can use different authentication methods and other VPN configuration settings as appropriate.

User tunnel is supported on domain-joined, nondomain-joined workgroupor Azure AD—joined devices to allow for both enterprise and BYOD scenarios. Device tunnel can only be configured on domain-joined devices running Windows 10 Enterprise or Education version or later. There is no support for third-party control of the device tunnel. You must enable machine certificate authentication for VPN connections and define a root certification authority for authenticating incoming VPN connections.

The sample profile XML below provides good guidance for scenarios where only client initiated pulls are required over the device tunnel. Traffic filters are leveraged to restrict the device tunnel to management traffic only.

This configuration works well for Windows Update, typical Group Policy GP and Microsoft Endpoint Configuration Manager update scenarios, as well as VPN connectivity for first logon without cached credentials, or password reset scenarios. For server-initiated push cases, like Windows Remote Management WinRMRemote GPUpdate, and remote Configuration Manager update scenarios — you must allow inbound traffic on the device tunnel, so traffic filters cannot be used.

If in the device tunnel profile you turn on traffic filters, then the Device Tunnel denies inbound traffic. This limitation is going to be removed in future releases. Depending on the needs of each particular deployment scenario, another VPN feature that can be configured with the device tunnel is Trusted Network Detection. To accomplish this, it will be necessary to use PsExecone of the PsTools included in the Sysinternals suite of utilities.

For guidelines on how to deploy a per device. Run the following Windows PowerShell command to verify that you have successfully deployed a device profile:. You can use the following Windows PowerShell script to assist in creating your own script for profile creation. Alternatively, the Trusted Root Certification Authorities store on the RRAS server should be amended to ensure that it does not contain public certification authorities as discussed here.Beginning with Windows 10 release Microsoft introduced the device tunnel option to provide feature parity with DirectAccess.

The device tunnel provides pre-logon network connectivity to support important deployment scenarios such as logging on without cached credentials and unattended remote systems management. Guidance for creating and deploying a device tunnel connection can be found here. Also, there can only be a single device tunnel configured per device.

You must remove an existing device tunnel before configuring a new one. First, the device tunnel is missing in the Windows UI after it is created. As you can see below, event though both a device and user tunnel have been provisioned, the Windows UI reports only a single Always On VPN connection, that being the user connection. However, the device tunnel does appear in the Network Connections control panel applet ncpa.

This is expected and by design. The device tunnel is not displayed to the user in the Windows UI as it is provisioned to the machine, not the user.

It appears on the Control Panel because the applet is capable of enumerating both user and system connections. This appears to be a bug; one which Microsoft is hopefully working to address. The Windows 10 Always On VPN device tunnel option allows administrators to enable scenarios previously supported with DirectAccess, including logging on without cached credentials and unattended remote support. Not all deployments require a device tunnel, but it is an important option available to administrators to address specific use cases.

I experience the PowerShell disconnected bug. The device tunnel is flakey. It will be fine for a while and sometimes just drop for no reason. I experience oddities with excluding domain names from using tunnel DNS servers both device and user actually. I am working with Microsoft trying to figure out why. DNS registration is flakey as well.

Hoping this will be better in Agreed, the device tunnel is still very much a work in progress. I believe those fixes will be backported to Very true. Today, the device tunnel is limited only to IKEv2 which is commonly blocked by firewalls and there is currently not TLS-based alternative or option.

Stay tuned! Another thing to consider is you need to specify the name, so maybe you add the powershell commands to the bottom of the profile powershell script.When configuring a Windows 10 Always On VPN device tunnel, the administrator may encounter a scenario in which the device tunnel does not connect automatically. An administrator can establish a device tunnel connection manually using rasdial. This scenario will occur when the device tunnel configuration is applied to a Windows 10 Professional edition client.

To ensure the device tunnel connects automatically, upgrade to Windows 10 Enterprise or later and join it to a domain.

Thanks Richard. It would be useful to understand the mechanism whereby Windows detects that it should try to initiate a connection. I see this mainly after waking a laptop from sleep. Plugging an ethernet LAN cable in and pulling it out after about 10 seconds sometimes triggers a connection. Seems a bit over-the-top. There has to be a more reliable way. This is a known issue, and one that was recently fixed by Microsoft. Tested on many different physical and virtual machines with various versions of Windows Interesting observation.

In theory, IKEv2 is supposed to be better at handling mobility. I have found that the situation is much improved with the latest updates for Windows 10 and though. KB has helped significantly with my test rig, although when reconnecting after waking the laptop seems to randomly pick the User or Device tunnel. Additionally, if it has picked a Device tunnel it very often establishes two simultaneous connections.

Great to hear. Anything after that would also include the fixes. I too am experiencing this issue of failure to connect after a sleep resume. This is when running KB as suggested above. Like Andy the issue is resolvable by completely disconnecting all network interfaces and then connecting them.DirectAccess was a technology that created 2 hidden VPN tunnels over SSL and encrypted all the data between your client machine and your local network.

The downside was that it required Windows Enterprise. The requirement list has changed to only the following:. Now that is a brief list huh?! I was surprised when I saw that all it needs is a fairly recent windows version.

There is one small caveat: for Device based tunnels, instead of user-based tunnels you will require update too. I will however try to keep all other best practices in place. For our server we will need to have it running as a domain controller already.

Click Finish and have the DirectAccess configuration setup complete. Click Add. Click Supply in the Request. Your certificates are listed in the details pane. Thats it! You can test this by setting your DNS to an external server such a google. Hope that helps! I would like the device tunnel working, so If this is what I need to do, your help would be greatly appreciated. SSTP Tunnels were supported for a brief moment, but got removed about 2 weeks after.

Note: Device Tunnel can only be configured on domain-joined devices using IKEv2 with computer certificate authentication.

Note: If you turn on traffic filters in the Device Tunnel profile, then the Device Tunnel denies inbound traffic from the corporate network to the client. Always On VPN provides connectivity to corporate resources by using tunnel policies that require authentication and encryption until they reach the VPN gateway.

By default, the tunnel sessions terminate at the VPN gateway, which also functions as the IKEv2 gateway, providing end-to-edge security. Support for machine certificate authentication. Support for servers behind an edge firewall or NAT device.

Ability to determine intranet connectivity when connected to the corporate network. Trusted network detection provides the capability to detect corporate network connections, and it is based on an assessment of the connection-specific DNS suffix assigned to network interfaces and network profile.

When compliant with conditional access policies, Azure AD issues a short-lived by default, 60 minutes IPsec authentication certificate that the client can then use to authenticate to the VPN gateway. At this time, Azure VPN conditional access provides the closest replacement to the existing NAP solution, although there is no form of remediation service or quarantine network capabilities.

For more details, see VPN and conditional access. You can achieve this functionality in Always On VPN by using the Device Tunnel feature available in version — for IKEv2 only in the VPN profile combined with traffic filters to control which management systems on the corporate network are accessible through the Device Tunnel.

Note: Device Tunnel can only be configured on domain-joined devices running Windows 10 Enterprise or Education version or later. There is no support for third-party control of the Device Tunnel. Support for both IPv4 and IPv6. Support for two-factor or OTP authentication.

Always On VPN specifically supports smart card both physical and virtual and Windows Hello for Business certificates to satisfy two-factor authentication requirements.

Group Policy is therefore not a dependency to define VPN profile settings because you do not use it during client configuration. You can configure Always On VPN to support both force tunnel the default operating mode and split tunnel natively.

Always On VPN provides additional granularity for application-specific routing policies. Note: Force Tunnel is supported by User Tunnel only.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Server Fault is a question and answer site for system and network administrators.

It only takes a minute to sign up. A potential workaround you could try is standing up a Server DNS server and implementing a DNS policy to do split-dns with geolocation awareness. Just a thought, but maybe set a connection script. Theoretically I guess you could always have it in the hosts file, and then they would just access the server from it's public ip even in the office. If you are using split DNS, there may be some cases where "internal" namespaces should be routed externally and not over the VPN tunnel.

In these scenarios you'll have to create "exclusions", which are essentially namespaces defined NOT to use the internal DNS servers. To do this you don't simply leave the DnsServers field blank, but you leave the DnsServers out of the element entirely.

However, there's no way to adjust the interface metric for a VPN connection in powershell, nor in VBscript, nor.

And changes there will not persist across reboots. I changed them both to Anything else including example.

When using automatic metric settings on all interfaces, for some reason the LAN Ethernet adapter has a lower metric the the device tunnel interface, but the wifi interfaces has a higher metric than device tunnel interface. I find it strange and I would have expected the device tunnel always would have the lowest metric, when using automatic metric assignment.

Ever wish your remote devices could easily update policies, install deployed applications, or configure changes? Windows 10 introduced device tunnels, Windows 10 improved the implementation, and development toward Windows 10 ironed out some remaining bugs. Before you dive into the steps below, make sure you have followed this core Always On VPN setup guide.

Windows 10 currently supports device tunnels on two editions: Education and Enterprise. Unlike user tunnels, device tunnels require a domain-joined client. Although you can use Windows 10it is better to use clients that are either Windows 10 fully patched or Windows 10 The next requirement is that all remote clients have a machine certificate issued by your public key infrastructure PKI for the purpose of client authentication.

You can check this by running certlm. View the details of the certificate and check that Enhanced Key Usage contains the Client Authentication value. If you do not see a certificate or do not have one for Client Authentication, you can issue the default machine certificate template and configure client auto-enrollment with these steps. Finally, no other device VPN profile can exist on the computer.

If you are not sure if another profile exists, open PowerShell as an administrator and run this command:. Under Propertiesselect Security and then select Authentication Methods.

Restart RRAS. By default, any valid certificate from any trusted certificate authority CA can complete machine certificate authentication to your environment. Just guessing here, but you probably only want machines with a certificate from your CA to be able to authenticate. For reference, you can find the CA common name in the Issuer attribute of the machine certificate you checked earlier. Right-click on the certificate, select Detailsand click on the Issuer attribute.

The sample profile you copied lists four IPs as examples. Ideally, your profile will only contain the critical services a client needs.

In the same folder where you saved the XML file, create a new PowerShell script and paste in the following code:. You should now have two files in your folder. The first one is an XML file.

To deploy your profile, you just need to run the PowerShell script you created under the System account of a client.

There are a few options for doing this. For a single machine or for testingyou can use the PSExec tool. Run it with the -S parameter and start PowerShell.

Finally, run the PowerShell script you created previously. The second option is to deploy the PowerShell script as a startup script in Group Policy. Startup and shutdown scripts process under the computer's account and run with the required permissions needed to create the VPN profile. Finally, you can deploy it with SCCM. Create a package for your script and allow it to run with administrative rights whether or not a user is logged on.

After using any of these options, verify that the VPN profile is installed. You should then be able to connect to an external network and communicate with one the IPs listed in the Route section of your profile. If you included a domain controller in that list, restart the client, connect to a remote network, and log on with a new user. It is a beautiful sight to see that a logon server is indeed available!
