Before AuthPoint can receive authentication requests from the Firebox:

1. Add the Firebox as a Firebox resource In AuthPoint, resources are the applications and services that your users connect to. in AuthPoint.
2. Add a Zero Trust authentication policy Authentication policies specify which resources users can authenticate to and which authentication methods they can use (Push, QR code, and OTP). for the Firebox resource or add the Firebox resource to an existing authentication policy.
3. (Optional) Add users and groups.

Configure a Firebox Resource

From the AuthPoint management UI:

1. From the navigation menu, select Resources.
2. Click Add Resource.
   The Add Resource page opens.



3. From the Type drop-down list, select Firebox.
   Additional fields open.



4. In the Name text box, type a descriptive name for the resource.
5. From the Firebox drop-down list, select the Firebox that you want to connect to AuthPoint.

This list only shows Fireboxes and FireClusters that you have added to WatchGuard Cloud, and the device status in WatchGuard Cloud must be Connected.

6. To configure the Firebox resource to accept MS-CHAPv2 authentication requests, select the Enable MS-CHAPv2 check box.
   Additional fields open.
7. In the NPS Firebox Server trusted IP or FQDN text box, type the public IP address or fully qualified domain name (FQDN) of the NPS RADIUS server.
8. In the Port text box, type 1812.
9. In the Timeout in Seconds text box, type 60.
10. In the Shared Secret text box, type the shared secret key that you specified in the Configure Microsoft NPS Server section.



11. Click Save.

After you add the Firebox resource in AuthPoint, the AuthPoint authentication server on your Firebox is Enabled. When you configure Mobile VPN with IKEv2 on the Firebox, you must add the AuthPoint authentication server to your Mobile VPN with IKEv2 configuration.

Add a Group in AuthPoint

You must have at least one user group in AuthPoint to configure MFA. If you already have a group, you do not have to add another group.

To add a WatchGuard Cloud-hosted group to the WatchGuard Cloud Directory:

1. Go to Configure > Directories and Domain Services.
2. Click the WatchGuard Cloud Directory domain name. If you have not yet added the WatchGuard Cloud Directory, click Add Authentication Domain and select the WatchGuard Cloud Directory.
   The New Group page appears.

3. In the Groups tab, click Add Group.
4. In the Group Name text box, type a descriptive name for the group.
5. (Optional) In the Description text box, type a description of the group.

6. Click Save.
   Your group is added to the WatchGuard Cloud Directory and to AuthPoint.

Add a Zero Trust Authentication Policy

Zero Trust policies specify which resources users can authenticate to and which authentication methods they can use (Push, QR code, and OTP).

You must have at least one Zero Trust authentication policy that includes the Firebox resource. If you already have Zero Trust authentication policies, you do not have to create a new authentication policy. You can add this resource to your existing authentication policies.

Users who not have an authentication policy for a specific resource cannot authenticate to log in to that resource.

To configure a Zero Trust authentication policy:

1. Go to Configure > Zero Trust. If you have a Service Provider account, you must select an account from Account Manager.
2. Click Add Policy.
3. Type a name for this policy.
4. In the Target section, from the Content drop-down list, select which groups this policy applies to. You can make multiple selections to add multiple groups.
5. In the Resources section, 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.
6. In the Conditions section, select the conditions that apply to this policy. When you add a condition to an authentication policy, the policy applies only to user authentications that match the policy and the policy conditions. For example, if you add a time schedule to a policy, the policy only applies to user authentications that occur within that time schedule. Users who only have a policy that includes a time schedule do not get access to the resource when they authenticate outside of the allowed times (because they do not have a policy that applies, not because authentication is denied). For more information, go to About Zero Trust Conditions

   Policies that have a Network Location do apply to Firebox resources.

   1. (Optional) To create a new condition, click Add New Condition. After you create a new condition, you must still add the condition to the policy.
   2. From the Type drop-down list, select the type of condition to add to the policy.
   3. From the Name drop-down list, select which condition of the chosen type to add to the policy.
   4. To add more conditions, repeat Step 6.

      If you add conditions to a policy, we recommend that you create a second policy for the same groups and resources without the conditions. Assign a higher priority to the policy with the policy objects. For more information about priority, go to About Zero Trust Policy Precedence.

7. In the Action section, select an option to specify whether to allow or deny authentications for the resources in this policy. In our example, we want to allow authentications.
   • Allow — Allow user groups in this policy access to the resources associated with this policy.
• Deny — Deny authentications when users in the groups associated with this policy try to authenticate to the resources associated with this policy.
8. If you allow access with this policy, select the Password and Push check boxes.

   QR code authentication is not supported for Firebox resources. OTP authentication is not supported for MS-CHAPv2 Firebox resources.

9. Click Save.
   Your policy is created and added to the end of the policy list.
10. Review the order of your policies and adjust as necessary. For more information about priority, go to About Zero Trust Policy Precedence.

Sync Users to AuthPoint from Microsoft Entra ID

To sync users from Microsoft Entra ID, you must add an Azure AD external identity in the AuthPoint management UI.

In AuthPoint, Azure AD external identities represent external user databases. They connect to user databases to get user account information and validate passwords. The queries you add to an external identity specify which users to sync from your Microsoft Entra ID database. They pull user information and create AuthPoint user accounts for the users that are found.

For detailed instructions to sync users from Microsoft Entra ID, go to Sync Users from Microsoft Entra ID.
