Getting Started with FortiGate

Overview of this book

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. Next, you will get acquainted with important topics like high availability and Vdoms. Finally, you will end the book with an overview of troubleshooting tools and techniques.

  • Identifying and monitoring the devices

  • Using the MAC address to control access

  • Creating policies based on device type

  • Enforcing endpoint control using the FortiClient software

We have already seen the option (inside the interface configuration) to enable device monitoring. The resulting data is included in the Device definition menu under the Device tab in the User & Device option. In the following screenshot, we have an Android tablet and a Windows laptop connected to our FortiGate unit:

MAC filtering is useful to limit access to our Wi-Fi network. If we enable a DHCP server on our interface, the default value is to assign an IP address to any MAC. We are able to apply a stricter control changing the option for Unknown MAC...
