Description

The FortiGate can be used as a DHCP server with the FortiWLC AP devices.  This article describes the format for DHCP option 43 to specify the controller IP that should be used to support this setup.


Scope

FortiOS v5.4, FortiWLC-SD v7.0-10


Solution

The following FortiGate CLI configuration could be used to configure the controller IP of 1.2.3.4:
config system dhcp server
edit 1
config options
edit 1
set code 43
set type hex
set value 2b 1a 31 2e 32 2e 33 2e 34
end

Note on ASCII to HEX conversion above:

- ASCII: +1.2.3.4

- HEX: 2b 1a 31 2e 32 2e 33 2e 34

The first 2 HEX values are required for the AP to correctly parse/read the HEX value representation of the controller IP.
