Registering FortiOS Carrier
In FortiOS 5.0, the Carrier registration process has changed. Devices are no longer shipped with Carrier functions built-in, so that administrators will have more leeway in configuring Carrier functions on existing devices.
A license is purchased from Fortinet, and is delivered by mail as a scratch card. The contained registration code is entered into the CLI according to the instructions on the card. The FortiGate will then factory reset itself into Carrier mode.
Only certain models support Carrier mode. Contact Fortinet Support for more information and firmware images.
