Add below to /etc/chilli/local.conf is correct
you can use dhcpstart and dhcpend options for chilli. These define the start and stop of the range. If set to 10 and 200 respectively, then chilli will allocate the range .10 - .200. These settings are not in the chilli/defaults file, but you can add the chilli options to your chilli/local.conf directly.
Thank you Mr. David
