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.

As we said in Chapter 1, UAG has TMG to act as its very own Firewall, but if you want additional protection, you can place UAG behind another firewall, and you can also place a firewall behind UAG, in between it and the corporate network. As always, make sure that the firewalls are configured to route traffic properly, and have the appropriate ports opened.

On the Internet side, there's an additional requirement. The external interface needs to have 2 IP addresses (those are IPv4 addresses), and they have to be consecutive. There are two reasons for this. One is that each one of the 2 DA IPSec tunnels needs to bind to a dedicated IP, so you need two. The second reason is for Teredo—Teredo needs to detect the type of NAT used on the Client side, because it cannot work with all types...
