SecureAuth RADIUS logs are not showing the VPN clients IP address

    Applies to:
  • Legacy SecureAuth IdP
Deployment model:
  • On Premises
  • Version Affected:  All


    When using a SecureAuth IdP RADIUS server integration with Palo Alto Networks GlobalProtect Gateway clients or Portal access, RADIUS server authentication logs may show the endpoint IP as the IP address of the VPN server.


    GlobalProtect does not send the client IP address using the standard RADIUS attribute Calling-Station-Id. However, Palo Alto Networks PAN-OS v7 includes a new RADIUS attribute (PaloAlto-Client-Source-IP) that contains the client IP address. This attribute can be enabled via the Palo Alto Networks administration shell to send the client IP to the SecureAuth IdP RADIUS server.



    1. Connect to the Palo Alto Networks administration shell

    2. Enable the PaloAlto-Client-Source-IP client IP attribute to be sent to the SecureAuth IdP RADIUS server by entering

    set authentication radius-vsa-on client-source-ip

    3. On the RADIUS server go to the RADIUS Clients tab and change the RADIUS End User IP field so it says PaloAlto-Client-Source-IP then save.



    Special Considerations:

    Note that UserHostAddress in the realm audit logs will still show as the IP address of the RADIUS Server ( if installed on the same machine as IdP) not the end user IP, this is expected behaviour.

    However Adaptive Authentication will see the correct end user address:

    The RADIUS server logs will also report the correct end user IP address:
