Works for me using following config :

dhcp.lan=dhcp
dhcp.lan.interface='lan'
dhcp.lan.start='100'
dhcp.lan.leasetime='12h'
dhcp.lan.dhcpv6='server'
dhcp.lan.ra='server'
dhcp.lan.dhcpv4='server'
dhcp.lan.limit='1'
dhcp.odhcpd=odhcpd
dhcp.odhcpd.leasefile='/tmp/hosts/odhcpd'
dhcp.odhcpd.leasetrigger='/usr/sbin/odhcpd-update'
dhcp.odhcpd.loglevel='7'
dhcp.odhcpd.maindhcp='1'

Client is assigned 192.168.1.100 which is within the configured range :
