No.

in rc.firewall (line 124):
${fwcmd} add 50 divert natd all from any to any via ${natd_interface}

This line only NAT's traffic going in and out of your upstream interface.

in "OPEN" configuration it NATs the traffic from LAN and DMZ -to/from- internet.
Not between the LAN and DMZ area, which is what you need.

You could look into setting up your own little proxy DNS (such as pdnsd).
Add the servers to hosts file on your workstations, or make it NAT the way you want.
