Configure an Always On VPN Configuration for Chromebooks Using the Google Admin Console

Chromebooks support Always On VPN through extended support for the GlobalProtect app for Android. In an Always On VPN configuration, the secure GlobalProtect connection is always on. Traffic that matches specific filters (such as port and IP address) configured on the GlobalProtect gateway is always routed through the VPN tunnel. By enabling your end users to run the GlobalProtect app for Android on their Chromebooks, you can ensure that they are always connected to GlobalProtect and have access to always on security.
The GlobalProtect app for Android is supported only on certain Chromebooks.
Chromebooks that do not support Android applications must continue to use the GlobalProtect app for Chrome. However, these Chromebooks will not support Always On VPN.
If the GlobalProtect app for Android is installed on a Chromebook for Always On VPN capability, the GlobalProtect app for Chrome should not be installed on the same Chromebook.
Use the following steps to configure an Always On VPN configuration for Chromebooks using the Google Admin console:
The following steps are applicable only if you Deploy the GlobalProtect App for Android on Managed Chromebooks Using the Google Admin Console. AirWatch does not currently support Always On VPN configurations for the GlobalProtect app for Android on managed Chromebooks.
  1. From your Palo Alto Networks firewall, Set Up Access to the GlobalProtect Portal.
  2. Define the GlobalProtect Agent Configurations.
  3. Customize the GlobalProtect App.
    • To configure the GlobalProtect connection to be always on, set the Connect Method to User-logon (Always On).
    • To prevent users from disabling the GlobalProtect app, set the Allow User to Disable GlobalProtect App option to Disallow.
  4. Enable transparent authentication for GlobalProtect.
    To prevent users from skipping GlobalProtect authentication prompts and thereby bypass the GlobalProtect connection upon disconnecting from GlobalProtect, configure one of the following options for transparent authentication:
    • Enable users to authenticate to GlobalProtect transparently using client certificate authentication.
    • Enable the GlobalProtect app to save both the username and password for transparent login.
      1. From your portal agent configuration (NetworkGlobalProtectPortals<portal-config>Agent<agent-config>), select Authentication.
      2. Set the Save User Credentials option to Yes.
      3. Click OK twice to save the portal agent configuration.
  5. Commit your changes on the firewall.
  6. Prevent Chromebook users from bypassing GlobalProtect using Chrome OS VPN settings.
    1. Log in to the Google Admin console as an administrator.
    2. Force GlobalProtect app installation on all managed Chromebooks.
    3. Blacklist the Chrome settings (chrome://settings) to prevent users from modifying any VPN settings:
      1. Select Device ManagementChrome managementUser Settings.
      2. In the Content > URL Blocking area, enter chrome://settings in the URL Blacklist text box.
