Overview of this book

Microsoft Forefront Unified Access Gateway (UAG) is the latest in a line of Application Publishing (Reverse Proxy) and Remote Access (VPN) Server products. The broad set of features and technologies integrated into UAG makes for a steep learning curve. Understanding all the features and abilities of UAG is a complex task that can be daunting even to experienced networking and security engineers. This book is the first to be dedicated solely to Microsoft Forefront UAG. It guides you step-by-step throughout all the stages of deployment, from design to troubleshooting. Written by the absolute experts who have taken part of the product’s development, official training and support, this book covers all the primary features of UAG in a friendly style and a manner that is easy to follow. It takes you from the initial planning and design stage, through deployment and configuration, up to maintenance and troubleshooting. The book starts by introducing UAG's features and and abilities, and how your organization can benefit from them. It then goes on to guide you through planning and designing the integration of the product into your own unique environment. Further, the book guides you through the process of publishing the various applications, servers and resources - from simple web applications to complex client/server based applications. It also details the various VPN technologies that UAG provides and how to take full advantage of them. The later chapters of the book educate you with common routine “upkeep” tasks like monitoring, backup and troubleshooting of common issues. Finally, the book includes an introduction to ASP, which some of the product's features are based on, and can help the advanced administrator with enhancing and customizing the product.

Advanced application types allow UAG to provide access to applications which are not classic "web" applications, and were not designed to be published. As you've seen in Chapter 4, UAG has Host Address Translation ( HAT), a clever mechanism that parses web-based content, such as ASP and HTML pages, and translates the links found in them in real time. If this process were performed, the links that show up on the user's browser would all point to URLs that have the internal server name, and the browser would not be able to resolve them. The translation changes the link to point to the UAG server's public hostname, and the added unique signature helps UAG understand the request and send it to the appropriate internal server.

With some applications, this is not possible. For example, if the application uses complicated code to access the internal server, UAG may not be able (fully or partially) to parse the links, and as a result, the client will try to directly access...
