Portal policy configuration is available in Authentication > Portals > Policies.
To determine policy priority, FortiAuthenticator attempts to match the portal access request to each policy, starting with the top policy in the list, and moves down until a match is found. Policy priority can be re-arranged by selecting the up and down icons next to each policy in the list.
You can change between Captive portals and Self-service portals views using the toggle in the top-right corner of the GUI.
For more information on the captive portal workflow, click the help icon in the top-right corner of the GUI, and select an access point/NAS.
