I would recommend creating a back-to-back DMZ and placing the Web servers in the DMZ. ISA is not your only solution for the back-to-back firewalls, but if you did use ISA, you could publish the entire 300 sites no problem. Using the SDK, you could script the creation of the destination sets and either Web publishing or Server publishing rules so that you don't have to enter those manually.

What is the best way to protect these sites that are running in registered PUBLIC (routable) address space. The "publishing" function of ISA (NAT as I understand it) seems as if if would be extremely cumbersome for this volume of sites. Any suggestions will be appreciated. ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jasonb54@xxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
