• Authenticate using the administrator credentials and proceed to the CLI interface.

Step 2: Navigate to Network Settings

Once you have accessed the FortiGate Firewall CLI interface, you need to navigate to the network settings section to configure the static IP. This can be done using the following command:

config system interface

This command takes you to the network interface configuration mode.

Virtual Domains

If you are working with virtual domains, you may need to select the appropriate virtual domain before proceeding further. This can be done using the following command:

edit <virtual-domain-name>

Replace <virtual-domain-name> with the name of the virtual domain you want to configure.

Network Interfaces

To configure the network interface for the static IP address, use the following command:

edit <interface-name>

Replace <interface-name> with the name of the network interface you wish to configure (e.g., "port1" for Ethernet 1).

Step 3: Assign the Static IP Address

To assign a static IP address to the network interface, use the following command:

set ip <IP-address>/<subnet-mask>

Replace <IP-address> and <subnet-mask> with the desired IP address and subnet mask for the network interface.

For example:

set ip 192.168.0.10/24

This command sets the IP address to 192.168.0.10 with a subnet mask of 255.255.255.0.

Additional Network Configuration

You may need to configure additional network settings, such as the default gateway and DNS servers. To configure the default gateway, use the following command:

set gateway <default-gateway-IP>

Replace <default-gateway-IP> with the IP address of the default gateway for the network.

To configure the DNS servers, use the following command:

set dns-service <primary-DNS> <secondary-DNS>

Replace <primary-DNS> and <secondary-DNS> with the IP addresses of the primary and secondary DNS servers, respectively.

Step 4: Apply the Configuration

After assigning the static IP address and configuring the necessary network settings, it is important to apply the configuration changes for them to take effect. This can be done using the following command:

end

Upon entering this command, the configuration changes will be saved, and the static IP address will be applied to the specified network interface.

Verification

To verify the configuration changes and ensure that the static IP address has been successfully assigned, use the following command:

show

This command displays the current configuration settings, including the assigned IP address, subnet mask, default gateway, and DNS servers for the network interface.

Additional Considerations

When configuring a static IP in FortiGate Firewall CLI, it is important to consider the following:

• Ensure that the chosen static IP address is not conflicting with any existing IP addresses in the network to avoid connectivity issues.
• Double-check the subnet mask and default gateway values to ensure proper network communication.
