Title: Understanding the ISA 2004 Access Rule Processing
Author: Stefaan Pouseele
Summary: In contrast to the simple trusted and untrusted ISA Server 2000 
networking model, the ISA Server 2004 uses a far more sophisticated and 
flexible networking model.  As a consequence the way you define your network 
and firewall policy in ISA Server 2004 is completely different and therefore 
also the logic behind the access rule processing done by ISA Server 2004. 
Because the result is not always what you might expect, we will explore in this 
article how ISA Server 2004 process the different rule lists and how a 
particular rule is chosen to validate a particular outgoing request.

Title: Understanding and Implementing ISA 2004 as an Application Firewall with 
the RPC Stateful Inspection Filter
Author: Thomas Shinder
Summary: ISA Server 2004 (ISA firewall) includes a number of technologies that 
provide enhanced security performance for corporate network infrastructures. 
The unique combination of security and functionality is highlighted by the 
application filters included with the ISA firewall right out of the box.
It is an important fact to realize that the RPC (Remote Procedure Call) 
protocol is used by many Microsoft networked applications, but that most of IT 
personnel, including network and firewall administrators, do not understand how 
the RPC protocols works. They don’t understand what potential problems are 
generated by the RPC protocol, and most importantly, they don’t know how to 
protect infrastructure servers. Typical network and firewall administrators 
just think that RPC is not secure and don’t even consider the fact that RPC 
access can be made secure, and this article will show you how to secure it.

Title: How to Make the ISA Firewall as Dumb as a Traditional Stateful Packet 
Inspection Firewall – Redux
Author: Thomas Shinder
Summary: This article first appeared in the ISAserver.org newsletter a couple 
of months ago. Its was so popular that I decided to update and enhance it and 
bring it online on the main ISAserver.org articles site. As always, I welcome 
your observations and opinions on the stuff we put up here on www.isaserver.org 
and hope you’ll use the discussion link at the beginning and ending of this 
article to further expand on what’s discussed in this article.

Title: Understanding ISA Firewall Networks (v1.1)
Author: Thomas Shinder
Summary: We’ve been fielding a ton of questions on the ISAserver.org mailing 
list in the last couple of weeks that focus on issues with the new ISA 
firewall’s concept of the network. This is one of the key differences between 
the ISA Server 2000 firewall and the new ISA firewall, ISA Server 2004. Because 
this is such a critical issue to understanding how the ISA firewall works, I 
figured it would be worth taking some time to discuss these issues with you so 
that you don’t run into problems with your ISA firewall configuration and 
access policy.

Title: Exporting Your SSL Certificate from IIS 6.0 and Importing To ISA Server 
2004 By Wayne Berry
Author: Thomas Shinder
Summary: Sometimes you want to take an SSL certificate that you already own 
that is installed on your web server and import it into the ISA firewall’s 
machine certificate store. This allows for encryption of outbound SSL from the 
ISA server to the published Web site in an SSL to SSL bridging scenario. One 
example is publishing your Outlook Web Access (OWA) site through your ISA 
firewall. This article guides you through the steps required to export your SSL 
certificate from you Internet Information Server (IIS) 6.0 Web site and import 
that certificate into the ISA firewall’s machine certificate store

Title: Unsupported, but nice: Customize Forms-based logon page in your ISA 
Server 2004 By Ladislav Solc
Author: Thomas Shinder
Summary: Did you know that you can customize Forms-based logon (FBA) page for 
OWA users in your ISA Server 2004? Yes. You can! This article shows you how.

Title: Enabling Full Outlook Client Access Anywhere using the ISA Firewall’s 
Secure Exchange RPC Filter
Author: Thomas Shinder
Summary: There’s no reason why your users ever need to be without their full 
Outlook MAPI client. When you bring an ISA firewall into your organization and 
configure Secure Exchange RPC Server Publishing Rules and pair this with an 
industry standard split DNS infrastructure, your users will realize all the 
productivity benefits that flow from the "Outlook Just Works" scenario. We use 
it everyday and so do our customers. Give it a try and you’ll be a believer 
too! Check out this article for all the details.
