  2. In Azure active directory, in the
    Manage
     section, click
    Conditional access
    Add
    .
  3. In the example here, we want make sure that all VPN connections from "VPN Users" group are controlled. Create a new policy with the following selections:

       Type
      VPN CA Policy
    • Users and Groups:
       VPN Users
    • Cloud Apps:

  4. Enable the new policy in
    Azure active directory
    Conditional access
    .
    Policy enabled in conditional access
    Policy enabled in conditional access

Marking the device as compliant in Azure AD

You can deploy compliance policy to users in user groups or devices in device groups. When a compliance policy is deployed to a user, all of the user's devices are checked for compliance. If a device doesn't have a compliance policy assigned, then this device is considered not compliant. To become a managed device, a device must be a
device that has been marked as compliant
. To mark the device as compliant in Azure AD:
  1. Sign in to the Azure portal.
  2. Click
    Device compliance
    Policies
    Create Policy
    .
  3. Create a new compliance policy without configuring any settings.
  4. Assign this policy to VPN users group.
    Example of a device compliance policy
    Device compliance policy

Adding conditional access to VPN profile

  1. Sign in to the Azure portal.
  2. Create a new VPN profile for Windows 10. Follow the steps similar to creating a base VPN profile. Enable the
    Enable conditional access for this VPN connection
     to ensure that devices that connect to the VPN are tested for conditional access compliance before connecting.

Configuring custom XML in profile using Intune

F5 Access for Windows Desktop supports the following three authentication flows:
  • Username
  • Certificate only (no prompt for credentials)
  • Username & certificate
These authentication flows can be configured through custom XML commands. You can enter Custom XML commands that configure the VPN connection in F5 Access profile using Intune.
The following example shows how a certificate is configured using custom XML.
<f5-vpn-conf>
<prompt-for-credentials>false</prompt-for-credentials>
<client-certificate>
<issuer>Microsoft VPN root CA gen 1</issuer>
</client-certificate>
</f5-vpn-conf>
