What is your load? How many clients? What does the CPU graph in the
Active Monitor say? In general, you don't describe a situation where
I'd expect the Qube to be heavily loaded. Even if it is, most likely
DNS won't be your heaviest problem and, to make things even worse,
adding secondary DNS won't do you any good since it'll only get
consulted if the primary's down (at which point you've got a whole
host of other problems...)

Let's first make sure that you *do* need to lighten the load on the
Qube before you go breaking a sweat there.

Short answer: not really. The Qube is not designed to be a router,
and for a DMZ you need to create two internal networks, one of which
is protected and one of which (the DMZ) is not. You simply don't
have enough Ethernet ports... Also remember that your Qube is serving
most of the services you'd normally place in the DMZ, so you'd need
your router to support a second network, not the Qube, right?
