Trying to find the correct option in FM to set the DNS servers in a given subnet in DHCP. Sample config from ubuntu wiki is below, but the option for domain-name-servers seems to be missing.

Added: same thing with default gateways, specifically option routers

Sample /etc/dhcpd.conf

default-lease-time 600;
max-lease-time 7200;
option subnet-mask;
option broadcast-address;
option routers;
option domain-name-servers,;
option domain-name "mydomain.example";

subnet netmask {

Big oversight you found. Not only is domain-name-servers missing, but routers is missing, too!

Ok, well glad I'm not crazy. We can manually add them to the conf file on the server and all works as it should. But as soon as the config change is written from FM, it overwrites and then it stops working. Push it in the next update and we'll keep testing.
