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.

This tunnel can be used to access domain resources and management servers. For example, it can be used to resolve DNS queries, update group policy, download Antivirus or Windows updates from an internal WSUS server. The second tunnel is referred to as the Intranet tunnel (also known as the "user" tunnel). This is the tunnel that actually lets the user connect to the rest of the organizational network.

From a user's perspective, this is not visible, but it's important to understand for two reasons. First, it is up to you to choose whether you want to allow full intranet access, or just remote management. Full intranet access will establish...
