It's way more trouble than it's worth in my opinion because you have to open so many ports, and very dangerous ones at that. With Exchange 2000, you not only have to open ports to other Exchange servers, but also to domain controllers. I believe that unless you have sophisticated intrusion detection systems and professional staff watching them all the time, you're probably better off opening only port 443 to your front-end (or Exchange 5.5 OWA) server.

I would like to move the OWA server to my DMZ and would like to know what ports I have to open on the private side to communicate with my exchange server. I understand that I only have to open port 80 on the public side (actually, 443 for SSL) Thanks!
