I am utilizing RouterOS CHR as a centralized DHCP server for all of my RB1100's and relaying the DHCP requests to the CHR - The issue I am having is I am getting addresses conflicts showing up in the leases under status when I know for sure those addresses are not in use. I had to for the time being disable conflict detection but I know that isn't the long term solution. I did run into this issue when relaying DHCP from a Cisco device and the solution was to disable Proxy-Arp on that interface. I did a little digging and it looks like in this case on the MT the proxy arp isn't enabled. Has anyone run into this issue or have idea's where to look next?

Thanks,
Doug
