This guide is intended for the system, network, and server administrators, who are responsible for the modifications that are required in your existing corporate infrastructure design in order to deploy Forefront UAG. It is assumed that the reader of this guide is familiar with network concepts, such as domain configuration, Certification Authority (CA) deployment, DNS configuration, network routing and protocols.

Infrastructure planning and designing consists of three phases: understanding the design requirements for Forefront UAG deployment, identifying your specific deployment goals, and understanding what changes are required in your infrastructure design in order to match those deployment goals.
