I currently have a sbs2003 running exchange 2003. I'm at home using your DHCP comcast network. In my router I have already setup DynDns and I'm able to access my network from the outside world using the domain name they sold me. I have my mx record hosted by godaddy.com. I wish to create a connection from the internet world to my exchange server 2003 and vise vesa. How do I do it? Getting a static IP address is not a option!
