Radius Settings

ARK2FA enables the definition of communication and security parameters used in integration with RADIUS-based infrastructures (VPN, Wi-Fi, NPS, etc.). Through these settings, RADIUS authentication requests are securely routed between the ARK2FA and NPS servers.

Main configurable parameters:

Radius Shared Secret Represents the shared RADIUS password used between ARK2FA and NPS (or the relevant RADIUS server). It must be entered exactly the same as the shared secret value defined on the NPS side. It ensures the security and mutual verification of RADIUS packets.

Adapter Server Endpoint Specifies the endpoint on which the ARK2FA RADIUS Adapter component listens. The IP address and port information are defined in IP:Port format (for example, 10.1.1.20:1812). It determines which service on the ARK2FA side the RADIUS requests will be directed to.

NPS Server Endpoint Represents the IP:Port information of the NPS server where the authentication process is performed (for example, 10.1.1.10:1812). After the 2FA check, ARK2FA forwards the RADIUS request to this endpoint or receives the response from this server.
