Description	This article describes how to update the license offline when there is no internet access to the FortiGate.
Scope	FortiOs 7.2.0 and above.
Solution	When the firewall is operated in the Transparent mode in the network and only used for Intranet traffic as a switch to inspect and forward the traffic, so without internet connectivity the license update or the FortiGuard database update is not possible automatically. In the previous version below 7.2.0, the internet was mandatory for updating or it was done with the help of FortiManager. From version 7.2.0 and later it is possible to download the offline license for the hardware device by logging into the support portal. Steps to Download the Offline License File: Login to the support portal from the registered account for the device license file is needed. https://support.fortinet.com/welcome/#/ Once logged into the portal, in the dashboard the assets information will be displayed, select the FortiGate.
