Configure AuthPoint MFA for Firebox Cloud Mobile VPN with IKEv2
The steps to configure AuthPoint and your Firebox Cloud are different based on the version of Fireware that you have. With Fireware v12.7.1 or higher, you can use the AuthPoint authentication server on your Firebox Cloud to make configuration easier, and you do not have to install the AuthPoint Gateway.
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.

Configure AuthPoint
Before AuthPoint can receive authentication requests from the Firebox Cloud, you must:
- Add the Firebox Cloud as a Firebox resource in AuthPoint.
- Add an authentication policy for the Firebox resource or add the Firebox resource to an existing authentication policy.
- (Optional) Add users and groups.
Configure a Firebox Resource
From the AuthPoint management UI:
- From the navigation menu, select Resources.
- From the Choose a Resource Type drop-down list, select Firebox. Click Add Resource.
- In the Name text box, type a descriptive name for the resource.
- From the Firebox drop-down list, select the Firebox Cloud 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.
- To configure the Firebox resource to accept MS-CHAPv2 authentication requests, click the Enable MS-CHAPv2 toggle.
Additional fields appear. - In the NPS Firebox Server trusted IP or FQDN text box, type the IP address or fully qualified domain name (FQDN) of the NPS RADIUS server.
- In the Port text box, type 1812.
- In the Timeout In Seconds text box, type 60.
- In the Shared Secret text box, type the shared secret key that must be the same as you specified in the Configure Microsoft NPS Server section.
- Click Save.
After you add the Firebox resource in AuthPoint, the AuthPoint authentication server on your Firebox Cloud is enabled. When you configure Mobile VPN with IKEv2 on the Firebox Cloud, 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:
- Go to Configure > Directories and Domain Services.
- 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.
- In the Groups tab, click Add Group.
- In the Group Name text box, type a descriptive name for the group.
- (Optional) In the Description text box, type a description of the group.
- Click Save.
Your group is added to the WatchGuard Cloud Directory and to AuthPoint.
Add an Authentication Policy to AuthPoint
Authentication policies specify which resources users can authenticate to and which authentication methods they can use.
You must have at least one authentication policy in AuthPoint that includes the Firebox resource. If you already have authentication policies, you do not have to create a new authentication policy. You can add this resource to your existing authentication policies.
Users that do not have an authentication policy for a specific resource cannot authenticate to log in to that resource.
To configure an authentication policy:
- From the navigation menu, select Authentication Policies.
- Click Add Policy.
- Type a name for this policy.
- From the Select the authentication options drop-down list, select Authentication options and 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.
- Select which groups this policy applies to. You can select more than one group. To configure this policy to apply to all groups, select All Groups.
- 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.
-
(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.
- 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.
Sync Users to AuthPoint from Azure Active Directory
To sync users from Azure Active Directory, 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 Azure Active Directory database. They pull user information and create AuthPoint user accounts for the users that are found.
For detailed instructions to sync users from Azure Active Directory, see Sync Users from Azure Active Directory.

-
(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).
For RADIUS authentication, policies that have a Network Location do not apply because AuthPoint does not have the IP address of the user.
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.
- 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.
Bind the RADIUS Resource to a Gateway
To use RADIUS authentication with AuthPoint, you must have the AuthPoint Gateway installed on Azure and you must assign your RADIUS resources to the Gateway in the AuthPoint management UI. The Gateway functions as a RADIUS server.
