I might be mis-remembering how our stuff is set up, but I don't think the Mikrotiks write anything back to Sonar. Basically, we assign an IP to a MAC in Sonar. That is written to the DHCP server in Mikrotik (basically create a DHCP reservation). Client radio connects and the DHCP request is forwarded to the Tik with the DHCP server running. The Tik assigns the IP and away we go. Sonar doesn't know about successful DHCP assignment or not, we always check the DHCP server to see if it is Waiting, Offered, or Bound. But ours might be quite a bit different without Option 82.
