Fortigate guest user accounts - create, edit, delete and deploy
The guest user accounts are special in Fortigate and unlike regular local Firewall user accounts. The flow of creating them is:
Let's configure it.
First, you create Groups, which serve, in this case, as a template for various parameters users can/must have later:
User & Device -> User Groups -> New .. -> Type: Guest
If you enable "Batch Guest Account Creation" then all the configs become grayed out and all the details of the to-be created users will auto-randomly generated.
(Optional) Create Guest users admin to manage them and assign relevant Groups
Such admin can only see the page of managing these Guest users and that is it.
System -> Administrators -> New .. -> Type: Restrict admin to guest account provisioning only:
This admin has to have access to the Management IP as a usual admin:
Create Guest users
User & Device -> Guest Management -> New ..
Pay attention to the right upper corner to pick the correct group for the new to-be created user.
Use the created Groups
Finally, we can use the Guest groups in Security rules or WiFi SSID for the Captive Portal for authenticaton.
Here is the example of Security rule. A user will have to first browse somewhere to get the login page.
