As we know, each network interface has a unique MAC address (Media Access Control, a unique identifier used to communicate on the physical network segment). The devices and computers connected to our network match every IP address to a MAC address and this information is saved in the ARP cache. The data in the ARP cache is used until their expiration time is reached. So if a cluster should be presented with the MAC addresses of the physical adapters on the different FortiGate units, this would make high reliability impossible because network connected devices would keep searching the MAC address of a failed FortiGate unit until the ARP cache expiration. The solution used for the FGCP protocol, for example, is to assign a virtual MAC address for every single network interface on the primary unit in the cluster. If a failure occurs on the unit, there will be no change in the MAC associated with the highly available IP address. To update the layer 2 switches that are directly...

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.
