The MAC address list in the DHCP responses is 00:50:56:fa:90:62. I've performed a packet trace on the host's switch port and found that the incoming DHCP response messages have a different MAC address than that of the DLR gateway, yet the IP address in the packet lists the gateway IP address. When using the DHCP Relay feature on the DLR to relay DHCP to an Edge, the incoming packets from the DLR gateway are blocked by the L2 firewall rule. My intention is to only allow VMs on this network to only talk to the gateway and not to each other.
I have a DLR with a gateway MAC address of 02:50:56:56:44:52 and I setup L2 firewall rules to only allow traffic to/from this MAC on the logical switch that the DLR is a gateway for.
