As always, there are two camps on this. One camp wants to blow holes in the
firewall to permit the FE to talk to the BE. The other wants to avoid that.
See "Figure 1 Secure Firewall Structure" here:
<http://www.microsoft.com/technet/security/prodtech/exchangeserver/secmod44.
mspx>
So, Microsoft favors the FE and BE servers on the same security zone, when
their ISA server is used as reverse proxy.
Have fun arguing with Microsoft. When you convince them and they change
their document, let us know. Otherwise, we already know your opinion, so
thanks for sharing.

About why putting a front-end, Internet facing, Exchange Server on the
same security zone as the back end Exchange servers. I'd like to
understand the misconceptions that underlie that assertion, so that we
can shoot them down and show how foolish they are.
Thanks!
