FortiGate from Fortinet is a highly successful family of appliances enabled to manage routing and security on different layers, supporting dynamic protocols, IPSEC and VPN with SSL, application and user control, web contents and mail scanning, endpoint checks, and more, all in a single platform. The heart of the appliance is the FortiOS (FortiOS 5 is the latest release) which is able to unify a friendly web interface with a powerful command line to deliver high performance. FortiGate is able to give users the results they usually achieve at a fraction of the cost of what they would have to invest with other vendors.This practical, hands-on guide addresses all the tasks required to configure and manage a FortiGate unit in a logical order. The book starts with topics related to VLAN and routing (static and advanced) and then discusses in full the UTM features integrated in the appliance. The text explains SSL VPN and IPSEC VPN with all the required steps you need to deploy the aforementioned solutions. High availability and troubleshooting techniques are also explained in the last two chapters of the book.This concise, example-oriented book explores all the concepts you need to administer a FortiGate unit. You will begin by covering the basic tools required to administer a FortiGate unit, including NAT, routing, and VLANs. You will then be guided through the concepts of firewalling, UTM inside the appliance, tunnelling using SSL, and IPSEC and dial-up configurations.

One of the two consoles will be dedicated to watch the results of the debug commands. The second console will be dedicated to launch commands, such as ping and traceroute that we will use to trigger actions that will be visible in the first open console. In the following screenshot we have a diagnose sniffer packet port1 icmp command running on the session opened to the left-hand side and an execute ping command on the session opened on the right-hand side window:
