Here is what I have:

Some computers as
MACHINE1.SUB.DOMAIN.NET
MACHINE2.SUB.DOMAIN.NET
MACHINE3.SUB.DOMAIN.NET
In which I do not control the DNS, but an existing Active Directory Forest exists as:
DOMAIN.NET but no Exchange server exist or Active DNS, only legacy Unix DNS/Email.

I also have machines in a nat on
MACHINE4.SUB.DOMAIN.NET
as
MACHINE4.HIDDEN.NET

I also have an exchange server 5.5 on the border.
MAIL.SUB.DOMAIN.NET
and
MAIL.HIDDEN.NET

I want to moveto Active Directory inside the firewall and move the Exchange server off the border to inside and upgrade to Exchange 2000.

How do I get Exchange to work properly inside as outside. (MAIL.SUB.DOMAIN.NET & MAIL.HIDDEN.NET or MAIL.LOCALHOST or whatever...)

What should I need to name my Internal Domain/Forest?

There is not enough information to answer this question? You don't say how or with what you're running the Nat among other things.

Most nat devices have a way to forward "through" certain protocols to certain internal ip addresses. For the exchange server, you simply forward smtp, and pop3 if you want outside access to mailboxes thru pop3. The "real" address under external dns becomes the nat device's address. Your inside clients use the inside computer name.

I can't answer the Active directory. I can't figure out why you have multiple domain names, where your existing active directory IS, if you have specific firewall software or if you are calling some nat device a firewall or if you are using ICS. I also can't figure out what you want to end up with.
