OpenVPN RADIUS integration
Multi-Factor Authentication (MFA) is an extra layer of security used when logging into websites or apps. Individuals are authenticated through more than one required security and validation procedure that only they know or have access to.
Remote Authentication Dial-In User Service (RADIUS) is a protocol commonly used to authenticate, authorize, and account for user access and actions.
Arculix offers a simple RADIUS solution for adding MFA to OpenVPN. This step- by-step integration guide illustrates how to configure both the OpenVPN Access Server and Arculix RADIUS MFA authentication solution.
Prerequisites
Arculix RADIUS Agent that is configured and connected to your user directory. For example, Microsoft Active Directory (AD).
For more information, see the Arculix RADIUS Agent deployment guide.
User account with administrative privileges for the OpenVPN panel.
Arculix RADIUS Agent configuration
Follow these steps to configure the Arculix RADIUS Agent.
Log in to the Arculix RADIUS Agent as an administrator.
Open the radius-agent-config.env file with an editor.
The file is located in the installed directory of RADIUS Agent. RADIUS clients are configured in this setting.
At the end of the radius-agent-config.env file, set the following configuration for the ARA_CLIENTS attribute:
Note
The values should be separated by semicolons (;).
ARA_CLIENTS=<An optional name for your OpenVPN>;<Internal IP address of your OpenVPN>;<a shared secret>
For example, set:
ARA_CLIENTS=OpenVPN;192.168.1.50/32;testing12345
Save the file.
Run the following command to apply the changes:
docker-compose down && docker-compose up -d
OpenVPN™ Access Server RADIUS configuration
Log in to the OpenVPN Access Server web-based admin portal as an administrative user.
