Exchange 2010: CAS array not pingable or accessible

Here is my setup:

Exchange 2010

Two locations – Main and DR Site

Main Site

Two Exchange 2010 servers - HT, MB, CAS roles
CAS Servers - CAS1 (192.168.0.8) and CAS2 (192.168.0.9)
CAS Array – outlook.domain.com (192.168.0.11)

DR Site (Azure)
One Exchange 2010 Server – HT, MB, CAS roles
CAS Server – CASDR (10.10.10.8)
CAS Array – outlookdr.domain.com (10.10.10.11)
DNS entry for outlookdr.domain.com

First, everything works fine in the main site and we are adding Azure as the DR site.
I am able to ping CASDR from either Azure or the main site.
I am able to connect to CASDR from our test account (in Outlook and OWA) to our test database that is in Azure.
I am not able to ping outlookdr (10.10.10.11) from the main site or DR site.  Ping returns the correct IP address of outlookdr (10.10.10.11).

When I place CASDR into outlookdr, I am not able to access my test account via Outlook or OWA.
Why is this happening?

Thank you!
Exchange

I read what you posted and read through the links but Exchange doesn't know that it's running in an unsupported environment.  

Could we put aside the Azure part for the moment - (let's say it's located in our remote office) can you explain why the CAS array is not pingable?

You need to open your firewall ports. If you have any firewall. Also what design are you trying to setup. Active/Active or Active/Passive?

As per design, DAG cannot be setup with Azure.
All of life is about relationships, and EE has made a viirtual community a real community. It lifts everyone's boat
