I am trying to host a new Exchange 2003 system for internet mail. We currently use Godaddy POP3 email service. I have a single Windows 2003 DC running Exchange 2003. We have a Time Warner corporate account for internet access. My router and firewall has the outside IP supplied by Time Warner (72.x.x.x). Time Warner also provided 4 additional IP's. My server that is hosting Exchange is on my private network (192.x.x.x). I would like to redirect email to my in-house exchange server. I understand that I must create a MX record on GoDaddies DNS server pointing to my Exchange server. Can this be done without changing the IP of my server? If not how would configure the server and still maintain my private network? Thanks in advance rbrindisi@taxitechnology.com
