Fortigate 60D (FortiOS v6.0.5) - DHCP Conflict IP in Interface1
Hello, when trying to save any changes to the Interface1 screen, the DHCP server Starting IP reports Conflict IP and could not find this IP conflict in the Firewall ARP table.
My DHCP range is large and even using a windows program called "Advanced-IP-Scanner" to scan the entire network for IPs and DNS I could not find duplicate IP.
See attached file.

What's the interface address and subnet. You range has to fix in that network. I believe your error is the range is greater than the interface network.
You can test the error via the cli also.
homefgt (1) # show config system dhcp server edit 1 set dns-service default set default-gateway 192.168.1.99 set netmask 255.255.255.0 set interface "internal" config ip-range edit 1 set start-ip 192.168.1.110 set end-ip 192.168.1.210 next end next end
homefgt (1) # config ip-range
homefgt (ip-range) # edit 1
homefgt (1) # set end-ip 192.168.2.250
homefgt (1) # end start-ip: 192.168.1.110 and end-ip: 192.168.2.250 are not on the same subnet. object check operator error, -40, discard the setting Command fail. Return code -40
that should related to your window UI error.

My question would be why would you have a range that large on a 60D? Sixteen 254 address subnets is a bit substantial for such a small box.

I was thinking the same exact thing also.
