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.

DA is based on IPSec tunnels, and every packet that goes to and from each client has to be encrypted or decrypted. In addition to that, some clients will also require SSL encryption on top of that. All this is very CPU intensive work, so if you thought you can just grab some old machine and milk it to the bone, think again.

As always with regards to performance, it's not easy knowing for sure at what point the server will start to choke. Microsoft's official performance information suggests that a server with 2 quad-core Xeon processors running at 2.26 GHz, and with 16 GB of memory can sustain approximately 2300 users, each having a data transfer rate of 0.1 Megabit per second (MBPS). That does not mean that if you get this exact hardware configuration you can count on that number of users to be serviceable, because certain things...
