SonicWall Network Security Appliance Integration with AuthPoint

Deployment Overview

This document describes how to set up multi-factor authentication (MFA) for SonicWall Network Security Appliance with AuthPoint as an identity provider.

Your SonicWall Network Security Appliance must already be configured and deployed before you set up MFA with AuthPoint. Your SonicWall Network Security Appliance can be configured to support MFA in several modes. For this integration, we set up RADIUS authentication with AuthPoint.

This integration was tested with SonicOS Enhanced 6.2.7.1-23n of SonicWall Network Security Appliance TZ 400.

SonicWall Network Security Appliance Authentication Data Flow with AuthPoint

AuthPoint communicates with various cloud-based services and service providers with the RADIUS protocol. This diagram shows the data flow of an MFA transaction for a SonicWall Network Security Appliance.

Before You Begin

Before you begin these procedures, make sure that:

  • You have installed and configured the AuthPoint Gateway (see About Gateways)
  • End-users can log in to the SonicWall Network Security Appliance
  • A token is assigned to a user in AuthPoint

Configure SonicWall Network Security Appliance

Configure a RADIUS Server

To use the RADIUS authentication with SonicWall Network Security Appliance, a RADIUS server (the AuthPoint Gateway) must be configured in the users configuration.

  1. Log in to the SonicWall Network Security Appliance web UI.
  2. Select Users > Settings.

  1. Click Configure RADIUS.
  2. In the RADIUS Server Timeout(seconds) text box, type 60.
  3. From the User Name Format drop-down list, select Simple-Name.
  4. In the Primary Server section, in the Name or IP Address text box, type the IP address of your RADIUS server (the AuthPoint Gateway).
  5. In the Primary Server section, in the Shared Secret text box, type a shared secret to identify your RADIUS client.
  6. In the Primary Server section, in the Port Number text box, type the port for the RADIUS server (AuthPoint Gateway) to use to communicate with the RADIUS client (SonicWall Network Security Appliance). The default ports are 1812 and 1645.

  1. Select the RADIUS Users tab.
  2. Select Use RADIUS Filter-Id attribute on RADIUS server.
  3. From the Default user group drop-down list, select SSLVPN Services.
  4. Click OK.

Configure User Authentication Settings

Next, you must enable RADIUS user authentication in user authentication settings.

  1. Select Users > Settings.
  2. From the User authentication method drop-down list, select RADIUS.
  3. Click Accept.

Configure SSL VPN Server Settings

  1. Select SSL VPN > Server Settings.
  2. For SSL VPN Status on Zones, select WAN.
  3. In the SSL VPN Port text box, type the port to use.
  4. In the User Domain text box, type your domain.
  5. Click Accept.

Configure SSL VPN Client Settings

  1. Select SSL VPN > Client Settings.
  2. In the Default Device Profile list, click Configure.

  1. From the Network Address IPV4 drop-down list, select Create a new network.

  1. In the Name text box, type a descriptive network name.
  2. From the Type drop-down list, select Network.
  3. In the Network text box, type an IP address.
  4. In the Netmask/Prefix Length text box, type a network mask value.
  5. Click OK.

  1. In the Network Address IPV4 drop-down list, select the network item you created.

  1. Select the Client Routes tab.
  2. From the Networks list, select one or more networks and add them to the Client Routes list.

  1. Select the Client Settings tab.
  2. Configure your client settings. Click OK.

Configure AuthPoint

Before AuthPoint can receive authentication requests from SonicWall, you must specify the SonicWall client as a RADIUS resource in AuthPoint. You must also assign the SonicWall resource to the AuthPoint user group that will authenticate through SonicWall and bind the SonicWall resource to a Gateway.

Add a Radius Resource in AuthPoint

From the AuthPoint management UI:

  1. From the navigation menu, select Resources.
  2. From the Choose a Resource Type drop-down list, select RADIUS Client. Click Add Resource.

  1. In the Host text box, type the IP address for your SonicWall Network Security Appliance.
  2. In the User ID drop-down list, select User Name.
  3. In the Shared Secret text box, type the shared secret for your SonicWall Network Security Appliance.
  4. Click Save.

Add an Access Policy to AuthPoint

You must have at least one user group in AuthPoint for authentication with SonicWall Network Security Appliance, and you must assign an access policy for the SonicWall Network Security Appliance resource to that group. If you already have a group, you do not have to add another group.

In the AuthPoint management UI:

  1. From the navigation menu, select Groups.
  2. To add a new group, click Add Group. If you already have a group that you want to use, select the group to edit it.

  1. In the Name text box, type a descriptive name for the group.
  2. (Optional) In the Description text box, type a description of the group.

  1. In the Access Policy section, click Add Policy.

  1. In the Add Policy dialog box, from the Resource drop-down list, select the resource you want to add an access policy for.
  2. (Optional) To require that users type their password before they authenticate for this resource, enable the Require Password Authentication toggle.
  3. Select the authentication options that users in this group can select from when they authenticate.

    For SAML resources, if you select more than one authentication option, users must select one of the available options when they authenticate. For example, if you select OTP and Push, users can choose to type their OTP or approve a push to authenticate. You cannot require that they do both.

  1. Click Add.

  1. (Optional) Add one or more safe locations to your group. For more information about safe locations and detailed instructions to add them, see About Safe Locations.
  2. Click Save.

Before you assign users to a group, you must add the users to AuthPoint. You can manually add user accounts or import user accounts from an external user database. For more information on how to add user accounts, see Add User Accounts.

Bind the RADIUS Resource to a Gateway

To use RADIUS authentication with AuthPoint, you must have the AuthPoint Gateway installed on your corporate network and you must assign your RADIUS resources to the Gateway in the AuthPoint web UI. The Gateway functions as a RADIUS server. For more information, see About Gateways.

  1. From the navigation menu, select Gateway.
  2. Select the Name of the Gateway.
  3. In the RADIUS section, in the Port text box, type the port number used to communicate with the Gateway. The default ports are 1812 and 1645.
  4. In the Select a RADIUS resource drop-down list, select your RADIUS client resource.
  5. Click Save.

Test the Integration

To test the integration of AuthPoint and configuration of your SonicWall Network Security Appliance, you can authenticate with a mobile token on your mobile device. For RADIUS resources, you can choose one-time password (OTP) or push.

In this example, we show the one-time password authentication method.

  1. Run the SonicWall NetExtender client application.
  2. In the Server text box, type the SonicWall Network Security Appliance WAN Interface IP address and SSL VPN port.
  3. In the Username text box, type AuthPoint user name.
  4. In the Password text box, type your AuthPoint password and OTP. The OTP for your token is shown in the AuthPoint mobile app.
  5. In the Domain text box, type the domain for your remote SSL VPN connection.
  6. Click Connect.

  1. In the Security Alert dialog, click Accept.
