My question is that I am building a DMZ into our WAN/LAN, and I would like my end users to get their email through the DMZ. The exchange server was already installed on a server with IP of 10.8.x.x, and the DMZ uses IP address 192.168.x.x. How would I be able to get the IIS features on the DMZed server to point to the exchange server that is already running the Outlook Web Access on it?
