I am trying to learn Exchange 2003 by setting up my own server at home. I currently have Verizon DSL and I use No-IP.com for a dynamic DNS host. Port 25 has not been a problem and I have been able to send and receive mail. I haven't been able to get OWA to work from an external network so I have been trying to find the best solution to changing Port 80. Since this is for home/education use, I will not be able to obtain a Static IP address so that is out of the question.
Does anyone have any siggestions?
