Hi, I tried to find some information about how to configure OWA 2007 in an ISA 2006 back-to-back scenario. However I did not found what I was looking for. What I did is the following and I just what to check with you guys if this is secure and a best practice. I published OWA on the backend firewall just as described in many articles. This works fine, I can access OWA from within the perimeter network. Cool, but not useful. On the frontend firewall I used a web site publish rule to publish a https website. With no authentication configured. It works but is it secure? Your thoughts?
Hi Snowfresh! The way you've described is the only way I've been able to get it to work as well. I'm also wondering if this is the "intended" solution. Does anyone know how you're "supposed" to setup OWA publishing in ISA 2006 in a back-to-back configuration?

I think this is a similar issue to what I am experiencing. Though I am not sure what you are considering "no authentication". Is this the authentication in the ISA 2006 publishing rule where you set it to All Users instead of Authenticated Users? If so, I have the same issue. My post regarding the 1311 error on the front end ISA box is what happens when set for Authenticated Users. I have found documentation for setting up OWA 2007 with a single ISA, OWA 2003 with ISA 2004 back to back, but no OWA 2007 with ISA 2006 back to back. There are too many blind spots between the documentation. Since Exchange 2007 and ISA 2006 were "built for each other" one would think that the default Publising Rule settings would work as is...but this is obviously not the case. Will be keeping track of these threads for sure.
