Symptom: 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. Conditions: 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.
