1.2 General Settings Configuration
Now that you are in the configure mode, it is time to assign Port1, Port2 and Gateway IP addresses to truly bring the FortiBalancer appliance into the network infrastructure.
1.2.1 Configuration Guidelines
To better assist you with configuration strategies that maximize the power of the FortiBalancer appliance, please take a moment to familiarize yourself with the basic network architecture.
Figure 1-1 Basic Network Architecture
The table below shows the most critical pieces of configurations from the figure above:
Table 1-6 Basic Network Configurations

| 10.10.0.1/24 | Gateway IP Address |
| 10.10.0.2/24 | Management IP Address |
| 192.168.10.1/24 | Port2 Interface IP Address |
| 192.168.10.0/24 | NAT |

Table 1-7 General Settings of Basic Network Configuration
| Operation | Command |
| Configure interface IP address | ip address {system_ifname|mnet_ifname|vlan_ifname|bond_ifname} <ip_address> {netmask|prefix} |
| Configure gateway IP address | ip route default <gateway_ip> |
| View IP configurations | ping {ip|hostname} show ip address show ip route |
| Set up web UI | webui {on|off} webui port <port> webui ip <ip_address> |
| Assign the host name | hostname <host_name> |
| Save the Configurations | write memory |
1.2.2 Configuration Example via CLI
1.2.2.1 Assigning the IP Address for Interfaces
First, the Port1 Interface IP address needs to be assigned followed by the Port2 Interface, both with the appropriate netmask assignments. Now with our example network addresses and netmask designations, these commands should be executed as such:
FortiBalancer(config)#ip address port1 10.10.0.2 255.255.255.0
FortiBalancer(config)#ip address port2 3fff::bb 64
The port1 interface and the port2 interface cannot be on the same IP network. The CLI will issue a warning message and will not allow you to configure the two interfaces for the same network.
FortiBalancer supports changing the MAC address of the system interfaces by using the command “interface mac <interface_name> <mac_address>”.
FortiBalancer(config)#interface mac port1 00:30:48:81:54:9c
Note: The administrator will need to provide the method necessary to allow end-users to direct outbound traffic to a preferred route based on the IP and protocol type.
1.2.2.2 Assigning the IP Address for Gateway
The final step in this initial introduction of the FortiBalancer appliance to the network infrastructure requires you to define the Gateway IP address.
To define the gateway IP address:
FortiBalancer(config)#ip route default 10.10.0.1
1.2.2.3 Viewing the IP Configuration
To verify that FortiBalancer appliance is indeed actively deployed within this network infrastructure, you may ping both the gateway and backend server by using the “ping” command. To ping the gateway:
FortiBalancer(config)#ping 10.10.0.1
PING 10.10.0.1(10.10.0.1): 56 data bytes
64 bytes from 10.10.0.1: icmp_seq=0 ttl=128 time=0.671 ms
64 bytes from 10.10.0.1: icmp_seq=1 ttl=128 time=0.580 ms
64 bytes from 10.10.0.1: icmp_seq=2 ttl=128 time=0.529 ms
64 bytes from 10.10.0.1: icmp_seq=3 ttl=128 time=0.486 ms
64 bytes from 10.10.0.1: icmp_seq=4 ttl=128 time=0.638 ms
— 10.10.0.1 ping statistics —
5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max/stddev = 0.486/0.581/0.671/0.068 ms
To ping the backend server:
FortiBalancer(config)#ping 192.168.10.1
PING 192.168.10.1(192.168.10.156 data bytes
64 bytes from 192.168.10.1: icmp_seq=0 ttl=128 time=0.661 ms
64 bytes from 192.168.10.1: icmp_seq=1 ttl=128 time=0.581 ms
64 bytes from 192.168.10.1: icmp_seq=2 ttl=128 time=0.552 ms
64 bytes from 192.168.10.1: icmp_seq=3 ttl=128 time=0.484 ms
64 bytes from 192.168.10.1: icmp_seq=4 ttl=128 time=0.632 ms
— 192.168.10.1 ping statistics —
5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max/stddev = 0.486/0.581/0.671/0.068 ms
To verify or view the settings after configuring these critical IP addresses:
FortiBalancer(config)#show ip address ip address “port1” 10.10.0.2 255.255.255.0
ip address “port2” 192.168.10.1 255.255.255.0
FortiBalancer(config)#show ip route Destination Netmask Gateway default 10.10.0.1
Should changes be required, in most cases, administrators should deploy the “no” version of the command relating to the configured information to remove any incorrect information before entering the desired corrections. For example, executing the command “no ip address port1”, will remove the port1 IP address for you to then reenter the correct information.
1.2.2.4 Setting up the web UI
If administrators want to take full advantage of the web UI access to the FortiBalancer appliance, at least one unique IP address is required.
In our example, we use the port1 interface IP address as the default web UI IP address and the default port 8888 as the web UI port. At last, turn on the web UI function:
FortiBalancer(config)#webui on
It is time to open your browser of choice and point it to the FortiBalancer appliance. To do this, simply type in the address as such:
https://10.10.0.2:8888
Note: The IP addresses and other parameters throughout these examples are meant for demonstration purposes. To actually access your FortiBalancer appliance, you can designate the web UI IP address and port via the commands “webui ip” and “webui port”.
And now press “Enter”. The welcome screen should appear in your browser’s window, protected by the familiar prompt asking for user name and password. The response to this prompt is admin and admin, just as before. If this screen does not appear, verify the address and port designations for both the port1 interface and web UI port.
The FortiBalancer appliance web UI supports the following browsers:
IE (Recommended)
Firefox
Chrome
Browser resolution should be set to 1024×786 or higher.
1.2.2.5 Assigning the Host Name
With clustering technology, more than one FortiBalancer appliance may be used within a single network server farm. With this in mind, the OS allows you to assign a “name” to each FortiBalancer appliance for monitoring each device’s performance and configuration specifications. Once you’ve named your FortiBalancer appliance, the prompt will change from the default “FortiBalancer” to the newly assigned name:
FortiBalancer(config)#hostname SJ-Box1 SJ-Box1(config)#
1.2.2.6 Saving the Configuration
To save your configuration, use the following commands:
SJ-Box1(config)#write memory
Now your configuration is saved into the startup file which the FortiBalancer appliance calls upon at reboot.
