How was a static IP assigned in the FortiGate 60e?

[segmentation_fault]

I've inherited a rack system with a Fortigate 60e that was setup by some other company. I am trying to understand how they created a static IP ( 192.168.1.51 ) for a raspberry pi video camera device sitting in the site. When I go to "Addresses" I see this for the pi:

And under Addresses  I see this is where they assigned the static IP:

However, the confusing part is I don't see where Camera 1 points to pi003? If I edit the Camera 1 or pi003 I see no reference to each other?

pi003 is a layer 2 MAC address and Camera 1 is a layer 3 IP address.

What I am confused about is how is Camera 1 associated with pi003? See screenshots below for Camera 1 and pi003. I don't see any reference to each other in the settings:

They don't really relate to each other. They are just logical objects representing two different things: one is an object referencing a Layer 3 IP address and the other is an object referencing a Layer 2 MAC address. In this case they are belonging to the same device but there is no real connection on the FGT.

Now, re-reading your original question I think maybe you are asking how to create a static IP or IP reservation for DHCP? Is this so? If the FortiGate is the DHCP server for the network you can add a reservation for the L2 MAC address: https://docs.fortinet.com/document/fortigate/7.2.2/cli-reference/60620/config-system-dhcp-server (look at "config reserved-address" command) or under Interface settings in the GUI you can add DHCP reservations there too.

Correct. I am mainly interested to know how to assign static ips to some devices in the center. Do I go to DHCP Monitor -> Right mouse click on the device -> "Create DHCP reservation" -> "OK" ? I want the IP to be permanent even after a complete power outage/reboot of the system. See below:

Yes that will accomplish the same thing as the CLI instructions I posted.

If Camera1 or pi003 is already connected to the network, you can view the ARP table to verify if it is learned by Fortigate.

get system arp
