Hi. I run a 2003SP2 Exchange environment with a single Exchange server and a single OWA server in a DMZ. Over the years I've had to open more and more holes between the two networks as I've added features, etc. Someone told me I should bring the OWA server back behind the firewall and only open ports 80 and 443 to the outside. I would be usign NAT on my firewall too btw. Which method is more secure for a smaller environment?
