I'm trying to configuring my Exchange Server 2010 sp1 on Windows Server 2008 R2 to receive emails from the internet. i configured exchange and its working fine on this link https://fmggv.com/owa(fmggv.com is my local domain). I have a hosted domain name and website fmg.edu.in. My quetion is how to point local domain to external domain so that i can use mail.fmg.edu.in from outside the world to access Outlook web app. I have a public ip and using port forwarding to my local ip.
Please advise me asap.
