we have a cisco meraki mx60 firewall and im trying to setup a dhcp option 15 in a branch office that doesn't have an active directory domain.  id like all domain specific DNS traffic to go over the site to site and communicate with the DC, but Id like all other DNS traffic to be local, and accrding to the meraki site link below if we add DHCP option 15 and add our domain suffix this should work, and it doesnt seem to be.  I added the option then pointed the dhcp dns back out to open dns and they could no longer communicate with the Domain.

The Open DNS servers, out on the internet, are not going to have your network's internals names listed.  PC's need to point to internal DNS servers for local network name resolution.  Those DNS servers would then point out to internet DNS servers for internet name resolution.
