Once the FortiExtender is discovered, you must authorize it by associating it either with a virtual WAN interface or a VLAN interface.
To authorize the FortiExtender device in FortiOS:
- Go to Network > FortiExtender, and wait for the FortiExtender device to be discovered by the FortiGate.
- Bind the device to an interface and authorize it.
In FortiGate 5.4 and later releases, you must manually create either a virtual WAN interface of type FEX-WAN or a VLAN sub-interface, and link it to the FortiExtender as part of the authorization process, as illustrated below.
Make sure that the FortiExtender and the FortiGate are connected on Layer 2 by default. If they are not connected via Layer 2 but can reach each other via Layer-3 networking, configure the FortiExtender with static discovery using the following FortiExtender CLI commands:
config system management fortigate
set ac-discovery-type static
set server 192.168.1.99
set server fortinet.com
set discovery-intf lan port4
