Over the years there have been a number of questions about how to configure the ISA firewall in a “hardware” firewall’s “DMZ”. I have to admit that this question never made much sense to me, since I couldn’t figure out why the fledgling ISA firewall admin would want to create such a configuration. It seemed to be a simple affair to place the ISA firewall either in parallel or in a back to back configuration with the “hardware” firewall in front of the ISA firewall, allowing the ISA firewall to provide its superior level of protection nearest to the protected resources.
