![]() ![]() The ENA driver is not allowing for mac_adress change but the same has been success with vif driver. ![]() So that plan is to reuse this NIC's IP address and mac address to the virtual components, so the packet hitting the NIC will have source mac_address and IP known to VPC and can reach internet.įor this configuration, the original mac address of the NIC to be changed to some random so that only we can reuse it on the virtual devices inside the ec2 appliance. However, the NIC allocated from VPC is configured in a special manner, so that it will not have IP and no traffic will be generated from it, rather it will act more similar to a bridge. consider the case when we are running a L2 / 元 appliance in an ec2 instance and traffic generating from these virtual devices will have source_ip and source_mac generated by virtual switches in these appliances(VPC blocks this traffic). ![]() However, there are production requirements which requires the mac address of NIC to be changed. It is well known that mac address spoofing is not something aws supports for network interfaces and also aware of the fact that aws VPC does not allow traffic from unknown macaddress:IP combination.
