Required Configuration for Exposure
This issue affects firewalls with GlobalProtect gateway configured when an authentication profile utilizes a RADIUS provider and issues a supported authentication challenge.
To check if a GlobalProtect Gateway is using a RADIUS authentication profile, follow these steps:
- Navigate to Network > GlobalProtect > Gateways in the management interface.
- Click on your Gateway Name and go to the Authentication tab.
- Review the Client Authentication configuration to identify the associated Authentication Profile.
- Navigate to Device > Authentication Profile to check if the profile references a RADIUS Server Profile.
