I currently have OWA configured to be working internally in the network when people go to //servername/exchange. However, I need this to be working externally as well. I have ports 443 and 25 open on the router, and my A record and MX record on my hosting is pointing to the e-mail server. Am I missing something? I am behind a FortiGate FortiNet router (Fortigate-100A 3.00,build0474,061228). Everything seems to be in place but I cant understand for the life of me why this is not working. We are not and will not be using an ISA server.
