I'm having trouble deploying OWA to allow connections from outside my LAN. I
can access OWA with no problem from inside my LAN
(http://servername/exchange).

I have a single static IP that is filtered through my router. HTTP ports
80/443 go to server 192.168.254.xxx and SMTP port 25 go to server
192.168.254.xxx.

In order to access OWA I have configured the following:

1) Opened port 6040 at my router and forward requests to my Exchange server
192.168.254.xxx
2) Set IIS on my Exchange Server to listen on port 6040.

I can access OWA fine from my LAN at http://servername:6040/exchange. When i
try to access OWA externally, I am prompted for my credentials as expected
but when I enter Username, Password and Domain I am repeatedly asked for my
credentials until until I get the dreaded 'Error: Access is Denied' page. I
have tried every conceiveable combination DOMAIN\Username, username,
username@domain...etc.

What am I doing wrong?
