FortiGate-100 Administration Guide
Use the following procedures to create an HA cluster consisting of two or more
FortiGate units. These procedures describe how to configure each of the FortiGate
units for HA operation and then how to connect the FortiGate units to form a cluster.
Once the cluster is connected you can configure it in the same way as you would
configure a standalone FortiGate unit.

• To configure weighted-round-robin weights
To configure a FortiGate unit for HA operation
Each FortiGate unit in the cluster must have the same HA configuration. Use the
following procedure to configure each FortiGate unit for HA operation.
Note: The following procedure does not include steps for configuring interface heartbeat
devices and interface monitoring. Both of these HA settings should be configured after the
cluster is up and running.
1 Power on the FortiGate unit to be configured.
2 Connect to the web-based manager.
3 Give the FortiGate unit a unique host name.

may temporarily lose connectivity with the FortiGate unit as the HA cluster negotiates.
If you are configuring a NAT/Route mode cluster, power off the FortiGate unit and
then repeat this procedure for all the FortiGate units in the cluster. Once all of the units
are configured, continue with
