To configure the second FortiGate unit (host name FGT_ha_2)

1. On the System Information dashboard widget, beside Host Name select Change.

2. Enter a new Host Name for this FortiGate unit.

New Name                                  FGT_ha_2

3. Select OK.

4. Go to System > HA and change the following settings:

Mode                                           Active-Passive

Group Name                              example1.com

Password                                   HA_pass_1

5. Select OK.

The FortiGate unit negotiates to establish an HA cluster. When you select OK you may temporarily lose connectivity with the FortiGate unit as the HA cluster negotiates and because the FGCP changes the MAC address of the FortiGate unit interfaces.

To reconnect sooner, you can update the ARP table of your management PC by deleting the ARP table entry for the FortiGate unit (or just deleting all arp table entries). You may be able to delete the arp table of your management PC from a command prompt using a command similar to arp -d.

6. Power off the second FortiGate unit.

To connect the cluster to the network

1. Connect the port1 interfaces of FGT_ha_1 and FGT_ha_2 to a switch connected to the Internet.

2. Connect the port2 interfaces of FGT_ha_1 and FGT_ha_2 to a switch connected to the internal network.

3. Connect the port3 interfaces of FGT_ha_1 and FGT_ha_2 together. You can use a crossover Ethernet cable or regular Ethernet cables and a switch.

4. Connect the port4 interfaces of the cluster units together. You can use a crossover Ethernet cable or regular Ethernet cables and a switch.

5. Power on the cluster units.

The units start and negotiate to choose the primary unit and the subordinate unit. This negotiation occurs with no user intervention and normally takes less than a minute.

When negotiation is complete the cluster is ready to be configured for your network.
