We are a bit confused after reading many articles. documents, tutorials, looks like we are missing an important piece in our setup. We created a DMZ in our sonicwall firewall we assigned the front end server in the dmz. The back end is available to the dmz because for testing we opened all the ports from the DMZ to Lan
We currently have configured:
Front End Exchange Virtual Dir to re-direct to http://mail1
(Back End) which works great. So my co workers can go to https://mail2
, asked for credentials, then ask to log in to back end server http://mail1
and then to Outlook Web Access.
We want to close outside access to the back end server so people will enter through the DMZ Front End Server then find it's way to the back end.
After reading many articles especially the Microsoft Configuring Front End Exchange 2003, it really doesn't show a step that I have to do for the two servers to talk to each other. It's like it has all the tools to do it. We also found out WebDav was disabled so I enabled it on both front end and back end but the problem continues.
This is what I wrote on another site msexchange looking for the same help.
When we code the Virtual Directory for the /Exchange default web side to \\.\BackOfficeStorage . The front end (Mail2) ask for credentials and the gives us HTTP Error 404 - File or directory not found.
We also tried to code the Virtual Directory for the /Exchange to redirect to the backend URL (Mail) by using the fqdn mail.companyname.com/excha
nge. What happens next is Mail2 ask for credentials and then redirects to mail. But, with the firewall closed to the backend (mail.companyname.com/exch
ange) it fails. When the firewall is open to the backend and nat is set to redirect mail.companyname.com/excha
nge to the backend it works. But, service is being provided directly from the back end.
So our problem appears to be related to how the front end and the back end are communicating. How should the Local Path for exchange Virtual Directory be coded in a front and backend configuration? Are there other dependencies?
