Fortigate 90D – How to Tidy Up the IP Addresses

fortigateip

I have a doubt. IP addresses of the PCs connected to this network do not seem to change every time they connect to the network. I should tidy up the IP addresses, respecting the physical layout of the PC. The firewall is a fortigate 90d, while the firmware version is v5.0

I post a picture, to understand how the network is set:

–UPDATE–
I tried to reserve an IP address, but the PC network card fails to obtain the ip:

@Nroot: your explanation is not quite right. The FGT doesn't reserve an address for a specific MAC address unless manually configured to do so. Rather, the client requests the same address as previously obtained. And shortening the lease interval will just create more traffic, not more addresses - for the same reason.

If you want to control the address a host uses either assign static addresses or set up reserved DHCP addresses on the FGT.
