Domain 1: Domain 2:

Win2k Server Win NT Svr
Exchng 2000 Exchng 5.5

Currently ExSvr 2k in Domain 1 is receiving our internet e-mail. ExSvr 5.5 is handling our internal e-mail with no connection to the internet. Basically we want to make Domain 1 as the DMZ and keep the back domain a seperate domain. How do I allow the users behind the DMZ access the mail server on the DMZ?

DMZ is supposed to be a dead end. Try and understand the concept of DMZ (DemilitarisedZone). It means that you are isolating a segment from your network to interface the rest of the world whereby only public access is allowed.

Why are people conflicting issues here? Your firewall protects your internal network from the rest of the world. You have services you would like to offer the rest of the Internet community or information you would like to share then you think about DMZ because this segment should not have any association with your internal network.

I realize the purpose of the DMZ. An publicy accessible machine, which includes the mail server that has a "real world" IP address. Therefore I would want to seperate that from the rest of my internal machines. I want/need those internal machines to get the e-mail from that mail server somehow through the back-end firewall of the DMZ.
Correct me if my theory is mixed.
