About This User's Guide
This manual is designed to guide you through the configuration of your ZyWALL for its
various applications. Generally, it is organized as follows.
• Introduction (ZyWALL, web configurator)
• Features (by menu item in the web configurator)
• Overview, including background
• Web Configurator screens
• Appendices
Intended Audience
This manual is intended for network administrators, or people who have a good knowledge of
TCP/IP networking concepts and topology, who want to want to configure the ZyWALL using
the web configurator.
1 Read Chapter 1 on page 53 chapter for an overview of features available on the
ZyWALL.
2 Read Chapter 3 on page 65 for web browser requirements and an introduction to the
main components, icons and menus in the ZyWALL web configurator.
3 Read Chapter 4 on page 75 if you’re using the wizards for first time setup and you want
more detailed information than what the real time online help provides.
4 It is highly recommended you read Chapter 5 on page 111 for detailed information on
essential terms used in the ZyWALL, what prerequisites are needed to configure a
feature and how to use that feature.
5 It is highly recommended you read Chapter 6 on page 125 for multiple ZyWALL
application examples.
6 Subsequent chapters are arranged by menu item as defined in the web configurator. Read
each chapter carefully for detailed information on that menu item.
