Assign dhcp addresses only if the mac addr is known

RouterOS General

Hi,
How can I assign the ip direction via dhcp only if the mac addr is a known machine?, only if the mac addr is in a list of known machines?.

Many Thanks.

first you need to configure the dhcp server (which i think you already did)

then first time give address to all your known clients and make them static (using IP->DHCP Server->Leases and click Make static)

then make you dhcp server to reply only to static mac by selecting the static-only option.


I hope it will help you

Many thanks arbabnazar

how make static the leases is ok,
I do not find where “make you dhcp server to reply only to static mac by selecting the static-only option” in the 5.11 firmware release.

Many thanks

Change arp property of the interface where dhcp server is running, from enable to reply only.
Also change uncheck the option on the dhcp server to add arp leases.
Make static leases on dhcp server, and make static entries in arp table (/ip arp).

Anyway you better configure radius to handle dhcp requests
