Master unit configuration: config system interface Let’s get to some configuration examples. That means you need another two networking devices to implement HA properly and up to four (because you need another switch or a pair between firewalls and LAN).

This can be mitigated by introducing another switch, possibly using another VRRP between to create full redundancy. It is necessary to connect another switch between the HA cluster members and the internet (NTD – Network Termination Device), thus adding another single point of failure. FGCP requirementsĪnother important thing to note here is that you will need additional networking equipment to configure HA. By tuning the timers, FortiGate failover time can be less than one second – if set properly and in ideal conditions. Like VRRP, HA will assign the virtual MAC addresses to cluster units, using gratuitous ARP to communicate between cluster units. Every cluster will have a primary FortiGate unit and one or more (up to three) secondary units. To join FortiGate units to a cluster, participants must have the same model, firmware, and hardware (same types or number of modules, etc.). When you join your firewalls to a cluster they will sync their configurations and function as one device, providing failover and load balancing the traffic if needed. Essentially, HA functions similar to VRRP, but one of the main differences is that you absolutely must have two same FortiGate models to achieve HA. High Availability is a FortiGate specific solution for providing redundancy. FGCP HA – High Availability with FortiGate Cluster Protocol WHAT is HA? After the default three seconds for the dead interval expire, slave will decide the master has failed and it will take over. Slave will not attempt to become the primary unit until it stops receiving hello messages. Hello packets are being sent on regular one second intervals from the master. FortiGate has a 1 second hello timer and a 3 second keep alive timer. Default VRRP timers change from vendor to vendor.
There are two types of advertisements – hello and dead interval packets. Like most of the network protocols, VRRP uses advertisements sent regularly between the participants. That way you won’t have members of the VRRP group sitting idle. In addition to all this, you can setup VRRP to load balance the traffic between VRRP participants. With VRRP, one device can be a FortiGate firewall, but the other device can be a simple router (that supports VRRP of course). VRRP is configured by creating a VRRP group with two or more FortiGates. Master unit will use the virtual IP address as its interface IP address but if it fails, the unit operating in slave mode will take its place, becoming the master itself and using the same virtual IP address.
VRRP uses the concept of virtual IP address and MAC address shared by master and slave devices. These protocols work under the same principals, except that you can use VRRP between two different vendors, while with HSRP you must go with Cisco. VRRP was developed as a non-vendor specific response to Cisco’s proprietary HSRP protocol.
VRRP: Virtual Router Redundancy Protocol VRRP history On the other hand, firewall vendors have developed another means of providing the hardware redundancy – High Availability. That’s why FHRP (First Hop Redundancy Protocols) protocols such as HSRP (Hot Standby Router Protocol) and VRRP were invented. That’s why it’s a good idea to also have two network devices, working in master/slave mode, where the second unit can take over if the first one fails. But in case your router/firewall stops working, having two or more WAN connections is not going to help you much. In times when each minute of network disruption can cost the company thousands of dollars, serious businesses tend to have redundant internet links. We will also go through configuration examples. We will compare two of the best solutions – VRRP (Virtual Router Redundancy Protocol) and HA using FGCP (FortiGate Cluster Protocol), outlining the pros and cons for each. In this article, we will discuss the importance of HA (High Availability) solutions for your FortiGate firewall(s).
