Fortigate External Captive Portal

[cbevilaqua]

Hello,

  We are using a Fortigate with FortiAp with our external server captive portal and Radius Authentication. We have configured all the settings needed to trigger the captive portal as shown in this page: https://cookbook.fortinet.com/using-an-external-captive-portal-for-wifi-security/ and the unauthenticated users are successfully redirected to our portal with the following URL parameters: ?login&post=http://10.10.12.1:1000/fgtauth&magic=01000887909fa2e7&usermac=90:f6:52:cb:00:b2&apmac=70:4c:a5:c2:02...   Basically, we need to identify the Gateway (Fortigate) in our platform by it's own MAC address, but actually, only the apmac parameter comes in the redirect URL. Is there any way of providing the Gateway MAC address in the URL?   Thanks!
