How can you configure an interface with a static IP address on a FortiGate device?

The process of configuring an interface with a static IP address on a FortiGate device involves accessing the specific settings for that interface and entering the desired IP address and subnet mask. This is essential for establishing a fixed point of communication within your network, which is critical for maintaining consistent routing and connectivity.

When setting a static IP, you need to provide both the IP address and the subnet mask to correctly define the network segment to which the interface belongs. This configuration ensures that the FortiGate device can communicate effectively with other devices on the same network and can accurately route traffic to different segments.

The other options do not effectively achieve the goal of assigning a static IP. For instance, enabling DHCP would not set a static IP but rather configure the interface to dynamically receive an IP address, which is not suitable for scenarios where a constant IP is required. Generating a dynamic IP via the command line interface contradicts the objective of using a static address. Lastly, resetting the device to factory settings would erase existing configurations, and while it could provide an opportunity to set the interface up again, it is not a direct method to set a static IP for the interface in question.
