Ina back-to-back scenario, you have an ISA (or other firewall) separating the 
DMZ from the Internet.  What you use for IP addresses is up to you, but using 
public IPs in a network that is not reachable from the Internet makes no sense.
If ISA is the frontline firewall, you would publish the DMZ servers using the 
frontline ISA just as if they were in its LAT (because they are).

  In a Back To Back ISA server setup, can the DMZ machines use public address 
rather then private address?

  And 2. If they are private address, how is the DNS machine published to the 
world if your running the primary server in the DMZ for your sites?



  Thank you,
