Hi Mates,

I am seeing the below error.

dhclient[58809]: unknown dhcp option value 0xe0


Can you help me? thanks!

Your DHCP server is sending an option of type 0xE0 (224) to the client.

According to this, that type is reserved for private use, so looks like your DHCP admin has done something special. (https://www.iana.org/assignments/bootp-dhcp-parameters/bootp-dhcp-parameters.xhtml)

You can probably ignore it.

What system is receiving a DHCP address, your FreeNAS?

Yes it is showing in the log file of the FREENAS.

I realize this is a necropost, but I may have an answer to help point you (or others) in the right direction.

What you're running into is DHCP option 224, which is specific to Fortigate DHCP servers. If you're comfortable with Fortigate's command-line interface, here's how you disable it:

config system dhcp server
edit <insert VLAN ID here>
set forticlient-on-net-status disable

That worked for me, though unfortunately I haven't found a corresponding setting via Fortigate's GUI.
