I have installed and set up Exchange Server 2013 within my LAN network. I have ran into an issue accessing the ECP or OWA through the web (outside the LAN) and can't figure out why. I have made sure that the virtual directories setting is appropriate for both the ECP and OWA. The domain used externally is exchange.example.com. (Example: exchange.example.com/ecp or exchange.example.com/owa) I made sure the extra dns/name server points to my WAN IP address on my Cisco router.
However, when I go to the domain exchange.example.com to log in, I receive a message. The server at http://exchange.example.com requires a username and password. The server says level 15 access.
I am not sure if this login is referring to my router, or my Exchange Server. I do try a ECP and OWA valid login, but it never works and just refreshes back to login window. I'm not even sure what type of credentials they are seeking, or if I missed a configuration step for this.
Note: The accounts that I want to log in to access email OWA and ECP are Windows Domain Accounts.
