Connect to FortiGate
When setting up a FortiExtender out of box with FortiExtender OS version 7.0.0 or later, you can connect the FortiExtender to a FortiGate in either of the following ways:
- Connect the FortiGate port in DHCP client mode (such as WAN1/WAN2) to a FortiExtender LAN port (1—3). In this option, the FortiGate interface acquires DHCP lease from the FortiExtender LAN DHCP server, and has a default gateway as the FortiExtender LAN interface IP address.
- If the FortiGate internal /LAN is running a DHCP server, connect the FortiGate to port4 of the FortiExtender, which acquires DHCP lease from the FortiGate DHCP server.
Wireless WAN extension to WAN interfaces of FortiGate
Connect the FortiGate WAN port (e.g., WAN1, WAN2) which is in DHCP client mode to a FortiExtender LAN port (LAN 1—3 in FortiExtender 201E/211E). In this option, the FortiGate WAN interface acquires DHCP lease from the FortiExtender LAN DHCP server, and has a default gateway as the FortiExtender LAN interface IP address, as illustrated above.
Wireless extension to internal LAN interface of FortiGate
In some scenarios, you may want to connect the FortiExtender to an internal LAN interface of the FortiGate (to use POE power or some other means). In this case, if the FortiGate internal LAN is running a DHCP server, connect the FortiGate to port4 (FEX-201E/211E) of the FortiExtender which acquires DHCP lease from the FortiGate DHCP server, as illustrated above.
