How to Configure RADIUS Authentication

  • Last updated on

Remote Access Dial-In User Service (RADIUS) is a networking protocol providing authentication, authorization, and accounting. The CloudGen Firewall can use RADIUS authentication for IPsec, client-to-site, and SSL VPN.

Configure RADIUS Authentication

Integrate the firewall with a RADIUS server and configure RADIUS for external authentication.

  1. Go to USERS > External Authentication.
  2. Click the RADIUS tab.
  3. Select Enable RADIUS Authentication to enable integration with RADIUS.
  4. Enter the Server Address and Server Port (default: 1812) of your RADIUS server.
  5. In the Server Key field, enter the pre-shared secret to authorize requests (no backslashes allowed).
  6. In the Group Attribute field, adjust the name of the attribute field on the RADIUS server if required (default: Login-LAT-Group).
  7. If your RADIUS server requires NAS credentials to be set, enter the NAS identifier (NAS ID), the NAS IP Address, and the NAS IP Port.
  8. Select the authentication scheme if group information should be retrieved from a different scheme.
  9. Click Save.

RADIUS authentication is now configured and can be used for IPsec, client-to-site, and SSL VPN.
