Many Exchange administrators have ISA Server firewalls (aka ISA firewalls) installed in their networks to provide application-level security to Exchange Server 2003 or Exchange Server 2000 services, including OWA, Exchange ActiveSync (EAS), and Outlook Anywhere (formerly known as Remote Procedure Call over HTTP—RPC over HTTP). With the release of Exchange 2007, many Exchange administrators will need to know how to protect their Exchange environments with ISA Server 2006, which is designed to work closely with Exchange 2007.
The topic of configuring various versions of the ISA firewall to protect various versions of Exchange has been discussed countless times in various publications. So, I won’t provide a step-by-step guide because many of the configuration steps are the same or similar to what you’ve used in Exchange 2003 and Exchange 2000.
I spent quite a bit of time searching the Internet for the resources I needed to successfully set up my environment. I’ll provide you with a basic overview of my environment as well as a list of the resources that I used at various stages so that you don’t have to hunt around as I did. . . .
