Anyone have good recommendations for how dns *really* needs to be setup
for dsfw?

I've read several tids & they all seem to mention having the dsfw
server as its own dns server, with the dsfw domain as its domain.

I have that setup on my live linux box that will run dsfw, I'm wanting
to make sure I get my dns configured properly for the *rest* of my
network before I install dsfw.

Currently I have 2 dns servers on my network, a primary and a
secondary. All my servers & clients have these as their dns servers,
with my current domain as their domain, which is different from my
eventual dsfw domain.

Is that going to be ok or what changes do I need to make?
