How to Delete a LAG Interface in Fortigate Firewall?
From the FortiClient interface, choose the PC to be unregistered or disabled under Monitor. Select ‘Block’ or ‘Unregister’ from the drop-down menu.
Go to the support site then select View Products. In the Serial Number section, enter the old unit’s serial number. Fill in the RMA Replacement box with the new unit’s serial number.
From the list of registered devices, select and hold the device you want to delete. Select Deregister. Select Deregister from the drop-down menu.
With a license, you can expect to get a lot more out of the Fortigate. However, it will operate without one. You won’t be able to access firmware or security updates, or any of the other features included in Forti Guard.
Go to System Settings and select the admin or administrators you want to remove. Click Remove in the toolbar or right-click and choose Delete to remove them. Select OK from the confirmation box if you wish to confirm their deletion.
