As we have said, FortiGate Cluster Protocol (FCGP) provides failover protection (the clustered firewall services are available even after a failure on the primary unit). To explain the FGCP protocol, we can start from a practical example, showing the steps required to configure two FortiGate units (
FortiGate_Slave) in a cluster to connect two networks linked to the interfaces
wan2 with high availability (HA). The schema of this scenario is the one we can see in the following diagram:
As shown in the previous image, four network interfaces are required for each firewall. At least one port on ...
