[Help] Configuring DHCP

Hello,

Im trying to configure CCR as DHCP server w/
ether 1 as WAN w/ ip add 122.4.x.x/32
ether 2 as Lan w/ ip add 172.16.0.1/16

I set DHCP server w/ address pool of static only to add manually the MAC in the Leases and add rate of 1M/1M

I have a problem in if the PC that is not in the Leases try to configure their IP address manually, they are not in the simple queue and has unlimited bandwidth usage.
