Description (partial)

external device within same subnet of inb-mgmt EPG, for TCP traffic APIC uses gateway mac as dest mac.

usually it is not an issue, if the external device is a firewall, then it will drop traffic.

for ICMP traffic we have seen the APIC sends traffic to correct dest mac which points in arp table.

but for TCP traffic it sends to GW mac.
