Configuring an Untrusted Wireless DMZ on the ISA Firewall - Part 2: Installing and Configuring the ISA Firewall: Date - Apr 17, 2005; Author - Thomas Shinder; Section - Articles; In part 1 of this two part series on how to create an untrusted wireless DMZ segment on the ISA firewall, we discussed the basic infrastructure elements required to make the solution work. We then went into detail on how to create a split DNS infrastructure to support the wireless DMZ segment. In this, part 2 of the two part series, we’ll finish up by going over the ISA firewall configuration details to complete the solution.
Allowing Intradomain Communications through the ISA Firewall (2004): Date - Sep 06, 2004; Author - Thomas Shinder; Section - Articles; The new ISA firewall’s enhanced support for directly attached DMZs has led to a lot of questions on how to allow intradomain communications through the ISA firewall from one network to another. This is a great question because you can now create multiple directly attached perimeter networks and allow controlled access to and from those perimeter networks. You can now safely put domain member machines on these DMZ segments to support a variety of new scenarios, such as dedicated network services segments that enforce domain segmentation. This article shows you have to create an Access Rule that allows the required protocols through the ISA firewall.
Publishing OWA Sites with a Unihomed ISA Firewall (2004) in Web Proxy Mode: Placing the Web Proxy ISA Firewall in a DMZ Segment: Date - Aug 10, 2004; Author - Thomas Shinder; Section - Articles; Are you forced to put the ISA firewall in a DMZ segment of your conventional stateful filtering firewall? Firewall politics getting you down? Don't worry! Even if they won't let you use the full firewall power of the ISA firewall, you can still squeeze out some significant stateful application layer inspection by using the unihomed ISA firewall in the "hardware" firewall's DMZ segment. This article has all the step by step info you need to get the job done.
Configuring Multiple DMZs on the ISA Firewall (2004) - Part 2: Installing the ISA Firewall and Creating the DMZ Networks: Date - Aug 07, 2004; Author - Thomas Shinder; Section - Articles; In the first part of this series on DMZ networking with ISA firewalls (ISA 2004), we discussed the DMZ concept and the differences between a typical DMZ segment and a perimeter network segment. Included in the discussion was a description of a four NIC setup on the ISA firewall, where one NIC was attached to an external network, the second NIC was attached to the Internal network, the third NIC was attached to a DMZ segment and the fourth NIC was attached to a perimeter network segment. In this article we will look at the details of creating and configuring the DMZ and perimeter network segments.
Configuring Multiple DMZs on the ISA Firewall (2004) - Part 1: Example DMZ and Perimeter Network Configuration: Date - Aug 06, 2004; Author - Thomas Shinder; Section - Articles; The ISA 2004 firewall (ISA firewall) makes it easy to create multiple DMZ networks directly connected to the ISA firewall. In contrast to the ISA Server 2000 firewall, where you had a simple networking model of "internal versus external", the ISA firewall’s new multinetworking feature allows you to configure multiple network types, and create Access Rules and routing rules between those networks. The new ISA firewall’s networking capabilities put it on par with just about any other network firewall on the market today. There are many possible DMZ networking topologies you can create with the ISA firewall. One topology that has worked very well for us is shown in the figure below. The ISA firewall DMZ configuration includes two ISA firewalls and four security zones.
Publishing Servers on a ISA Server 2004 Firewall Public Address DMZ Segment (v1.01): Date - Jun 18, 2004; Author - Thomas Shinder; Section - Articles; This article describes how to publish a public address DMZ host using Access Rules. This method allows you to use the public addresses your servers have already been using and leverage the full stateful application layer filtering power of the ISA Server 2004 firewall. Unlike traditional packet filter based firewalls (PIX, Netscreen, SonicWall, etc.), the ISA Server 2004 firewall performs stateful filtering and stateful application layer inspection on all communications moving through the firewall. Check out this article for a full discussion and step by step details on how ISA 2004 firewalls accomplish this amazing feat!
Front-end Back-end Exchange Server Trihomed DMZ Network Scenario: Date - May 17, 2004; Author - Thomas Shinder; Section - Articles; In this document, we will go over detailed procedures required to configure Microsoft Exchange Servers and the ISA Server 2004 firewall to support the front-end Exchange Server on a trihomed DMZ segment and the back-end Exchange Server on the Internal network. We've got a lot of ground to cover, so get started now and you'll be done by the end of the week!

Creating a Parallel ISA Firewall Configuration in a Netscreen DMZ: Date - Jan 17, 2006; Author - Thomas Shinder; Section - Tutorials / Configuration - General; 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.
