Connect to FortiGate

When setting up a FortiExtender out of box with FortiExtender OS version 7.0.1, you can connect FortiExtender to 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 FortiExtender, which acquires DHCP lease from the FortiGate DHCP server.

When setting up a FortiExtender out of box with FortiExtender OS version 7.0.0 or later, you can connect FortiExtender to FortiGate in either of the following ways:

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 LAN/internal interfaces of FortiGate

In some scenarios, you may want to connect FortiExtender to an internal/LAN interface of 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 FortiExtender which acquires DHCP lease from the FortiGate DHCP server, as illustrated above.
