ClearPass x FortiGate and FortiAPs

    Posted Mar 12, 2025 08:21 AM

    I have a ClearPass setup with Fortinet products (FortiGate, FortiSwitch, and FortiAP). Goal is to configure wired and wireless authentication with OnGuard health check. Wired authentication with health check is successful with the whole flow being as follows:

    1. User is not connected to internet. User has OnGuard installed on Windows PC. User health status is unknown. User connects to ethernet cable and gets authenticated initially but as UNKNOWN health, thus the enforcement policy enforces the UNKNOWN VLAN profile.
    2. Agent gets connected to ClearPass OnGuard when in UNKNOWN VLAN and performs the health check required. User in this example is healthy. Thus it will send to the ClearPass that the user is healthy. The health check policy is hit and it enforces a CoA bounce port message to the FortiSwitch port the user is connected to.
    3. The user gets disconnected for a few seconds then reconnects with the new information that the PC is healthy, thus it gets its IP from the HEALTHY VLAN.

    We want to replicate this process but for wireless authentication with health check, but the automatic CoA message is not disconnecting the user. Change of authorization is greyed out when attempting to change status after authentication. 

    I have tried the ArubaOS wireless attributes and there are no ports or anything blocked on the firewall and there are no ACLs or any restriction.

    What can I do to solve this problem or troubleshoot it more.

    Best Regards,

    Ali Serhan

    Hi Ali

    Are you using the correct AVP for terminating Wireless Session?  This is the Fortinet Radius Termination Action AVP in Wired and Wireless Scenarios. Did you had a check on this?

    Hello Shpat

    I just checked the document you shared and tested the AVPs. Didn't work. The problem is that the dynamic authorization is greyed out. 

    These are the AVPs I tried in multiple permutations but still didn't work. 

    These are the attributes I'm using for the wired and its working fine, but of course not working for the wireless.

    When adding the Device in Clearpass (in this case the Fortinet Wifi controller) is the COA enabled ?

    Just trying to understand the setup which you have in place. For Wireless service, do you have RADIUS Authorization enabled?

    ClearPass doesn't have a Dynamic Authorization template tied to the Fortinet vendor, and the wireless probably doesn't use the standard IETF option.  You'll likely need to determine what is required for the disconnect message against that vendor.

    That is correct. I have uploaded an xml file manually to the RADIUS dictionaries in ClearPass to include Fortinet attributes. The attributes are stated by Fortinet but they work only with FortiSwitch ports, but still not sure for wireless what should be done.

    You may need to contact Fortinet to figure out what is required for the disconnect message.

    Hi Ali,

    Do you have the radius-coa enabled in the Fortigate or Forticontroller or the device which acts as a wireless controller?

    config user radius
    edit "peap"
    set server "your-ip"
    set secret **********
    set radius-coa enable
    next
    end
