Firebox Cloud Mobile VPN with IKEv2 Integration with AuthPoint for Azure Active Directory Users

The steps to configure AuthPoint and your Firebox Cloud are different based on the version of Fireware that you have. Complete the steps in this section if your Firebox Cloud runs Fireware v12.7.1 or higher.

With Fireware v12.7.1 or higher, you can add AuthPoint as an authentication server on your Firebox Cloud. For this configuration, you must register and connect your Firebox Cloud to WatchGuard Cloud as a locally-managed Firebox or a cloud-managed Firebox. For detailed instructions to register and connect your Firebox Cloud to WatchGuard Cloud, see Add a Locally-Managed Firebox to WatchGuard Cloud and Add a Cloud-Managed Firebox to WatchGuard Cloud..

To configure AuthPoint MFA for a Firebox Cloud with Fireware v12.7.1 or higher that is not connected to WatchGuard Cloud, follow the steps in the Configure AuthPoint MFA for Firebox Cloud Mobile VPN with IKEv2 (Fireware v12.7 and Lower) section.

6. Select the resource that you created in the Configure a Firebox Resource section. If you want this policy to apply to additional resources, select each resource this policy applies to. To configure this policy to apply to all resources, select All Resources.

7. (Optional) If you have configured policy objects such as a Network Location, select which policy objects apply to this policy. When you add a policy object to a policy, the policy only applies to user authentications that match the conditions of the policy objects. For example, if you add a Network Location to a policy, the policy only applies to user authentications that come from that Network Location. Users who only have a policy that includes a Network Location do not get access to the resource when they authenticate outside of that Network Location (because they do not have a policy that applies, not because authentication is denied).

   Policies that have a Network Location apply to Firebox resources.

   If you configure policy objects, we recommend that you create a second policy for the same groups and resources without the policy objects. The policy with the policy objects should have a higher priority.

8. Click Save.
   Your policy is created and added to the end of the policy list.

   When you create a new policy, we recommend that you review the order of your policies. AuthPoint always adds new policies to the end of the policy list.
