OK.
Here are the config options I use in case it has any impact dnsmasq.conf: port=0 no-resolv no-poll interface=eq-mgmt bind-interfaces no-hosts dhcp-range=10.243.0.50,10.243.255.254,255.255.0.0,10m dhcp-option=3 dhcp-option=12 dhcp-option=option:ntp-server,10.243.0.2,10.243.0.3 enable-tftp tftp-root=/var/tftpboot tftp-secure dhcp-script=/bin/echo log-dhcp dhcp-optsdir=/etc/dnsmasq.d/opts/ Adding/removing line "option:router,10.243.0.1" to option file in the opts dir.
