Thanks. After posting I realized a /29 would be much cleaner as well. It
also helps with my backup situation as well. As only the /24 is BGPd

As for DNS. I'm open to any program on any platform as long as it has a GUI.
The project managers get/have to assign their own DNS names as new clients
come in. We're currently using SimpleDNS on Windows, but I'd switch to
anything if it handled the split horizon DNS. Mac, Linux, Windows..

For those unfamiliar, split horizon DNS is one term for handling DNS
differently for internal and external users. Users on the internet might get
www.fwiz.com resolving to  but once we get all the 1:1 NAT
done, we need internal users have www.fwiz.com resolve to It can
be done with 2 DNS servers and duplicate sets of records, but we add and
change records so often I'm really hoping we can find a solution that can
resolve internal and external requests differently depending on the source
IP. Does that explanation sound correct to you Chris?

You don't need four /30's.  If you think you may need to add devices
outside the firewall in the future, get a /29.  That leaves you with 6
total usable IP's, 4 extras.  There's no reason to burn all those
small subnets in this situation when a single /29 would serve you
equally well and actually better since it's cleaner.

What DNS server software?
