Aside from normal router & switch ACLs, ISA is the single line of defense.

Ahh…just had a thought.

 

It’s all labeling.

 

Jason, and others (not Jason’s fault), have been using the term DMZ.

 

Historically, is the term DMZ not taken literally as being completely 
firewalled off from the trusted networks, and what Jason is talking about is 
trusted network segmentation.

 

I betcha that’s why the Exchange team don’t support it…they think it’s 
a typical run of the mill DMZ…

 

Jim, isn’t MS’s Internal network segmented by usin ISA?? Including your 
mail servers?
