I have a DHCP relay for some of my clients. They were not able to communicate after getting an IP address. I found the MT was adding the MAC of the relay to the ARP table instead of the client's MAC address. However, the DHCP table had the correct MAC. Is this working as intended or a bug. I would like to be able to use reply only on this interface. But, if the add-arp does not work correctly, I won't be able to.
