Small problem DHCP server settings + mac reservation

[Tomas_Macek]

Fortigate 61f with fw 6.2.3 - settings DHCP server for LAN (in GUI). Saved three dhcp ranges (for example 192.168.1.50-90, 192.168.1.120-150 and 192.168.1.200-210). Now I try add reservation for any mac address - I inserted mac address and as ip value 192.168.1.55 - GUI show reports error that ip must be within ip range. I tried add 192.168.1.130 - same result. IP 192.168.1.201 works ok and I can save it. It's normal that GUI accepts ip from last dhcp range only? Or it's error in gui?

Hi Tomas,

It's not normal. IP reservation should work for all DHCP ranges.  If you are doing it from GUI, MAC address should already be in the DHCP monitor. You just right click on it and reserve the IP address. 

Thank You.

Yes, it's true about monitor. My problem -  I'm preparing Fortigate in my office before installing it in customer's network. So I can't use this way. It's not so big problem, only strange behaviout of GUI
