No. The DHCP client ID/MAC is part of the DHCP REQUEST packet. Doesn't matter what the underlying L2 address is.

Like I said before, last week, week before, I forget... You can use MAC-NAT aka translation bridging and MikroTik's DHCP server lease option "use-src-mac" to tie the DHCP request to the NAT'd/translated L2 address (it ignores the client ID). Thus restricting that customer to the same lease (IP) no matter what device they plug in. Then it does exactly what you say, Steve.

But 2 or more dhcp clients will receive the same ip assignment and the device will revert to a link local ip when is sends out a conflicting gratuitous arp on the broadcast domain, or never actually ack a dhcp offer

    I think you mean MAC-NAT. Yes. It's essentially translation
    bridging just like Canopy. Every device behind the SM would show
    up as the SM's MAC on the upstream/wireless side.

    So I get that the SM translates Macs into the SM MAC, this
    includes several devices? IF the SM is connected to a SW with
    several pcs ?
