FortiGate-800 Installation and Configuration Guide Version 2.50

Getting started

This chapter describes unpacking, setting up, and powering on a FortiGate Antivirus Firewall unit. When you have completed the procedures in this chapter, you can proceed to one of the following:

•If you are going to operate the FortiGate unit in NAT/Route mode, go to “NAT/Route mode installation” on page 41.

•If you are going to operate the FortiGate unit in Transparent mode, go to “Transparent mode installation” on page 59.

•If you are going to operate two or more FortiGate units in HA mode, go to “High availability” on page 73.

This chapter describes:

•Package contents

•Mounting

•Powering on

•Connecting to the web-based manager

•Connecting to the command line interface (CLI)

•Factory default FortiGate configuration settings

•Planning the FortiGate configuration

•FortiGate model maximum values matrix

•Next steps
