Hi,

From the Internet you have to access LAN via a real IP address. You have
to configure your FW to translate the LAN IP address  to a real IP
address.
Your sers than can access the Exchange through OWA like:
http://xxx.xxx.xxx.xxx/exchange

Well, to put it in the simplest term, my Exchange server is inside the
private network. That means it's behind the Routing and Remote Access
(RRAS) machine. No one can hit it direct from the Internet.

NAT has been setup on the RRAS interface and as you may know, NAT allows
you to redirect a particular port from the router to a particular port
on a particular computer on the internal network. I have configured the
NAT in such a way to refer any SMTP (25) and any HTTP (80) incoming
communications on the router's port 25 and 80 to port 25 and 80 on my
Exchange server. I can send and receive emails fine and that tells me
that port 25 is working like a champ.

The problem again is I cannot connect through OWA. OWA works fine inside
the internal network. How do I configure it to work from outside the
network? Thanks again for any help out there...
