Hi All,

I can not access email externally using OWA, however, i can access OWA internally.

Setup.

*Static IP: xxx.xxx.xxx.xxx
*ADSL/firewall modem installed with port forwarding 443 to internal ISA 2006 (web proxying)
* ISA 2006 setup as web proxy with single network card. ISA 2006 located behind ADSL firewall. Applyed single network adapter template.
* setup a rule for OWA publishig in ISA 2006....
*followed the setup instructions from the tutorials http://www.msexchange.org/tutorials/Publishing-Exchange-2007-OWA-ISA-Server-2006.html
* tried it many times but i still can't get access.

The problem...

When i get the OWA login page, i enter the domain\user and password and i get an error " You cannot log onto the ISA server. make sure your domain, user name and password is correct....displayed in yellow on the OWA web page...

I've checked the log and i can see that the connection is dropped straight after accepting the certificate.

The log error is what is shown below.

12239. The server requires authorisation to fulfill the request. access to the web server is denied. contact the server administrator

Also, i noticed that in the monitoring log that it forwards the request internally on http and not on https...

I used port forward to direct traffic directly to the internal exchange server and then used an external computer to login, and it works. However, when i port forward all 443 and 80 traffic to the ISA server, OWA fails. I have been working on this issue for the past 3 days and i am so frustrated. If anyone can help, it would be most appreciated.

Many many thanks in advance.

Musima.

I've found the problem.... i have incorrectly installed the certicate. Also, the external server name i.e owa.mail.org must the same name used in the all the way through the owa publishing rule. don't forge to update the host file on the proxy...
