Media access control address translation in virtualized environments
First Claim
1. A method for transmitting network packets through a network security device, the method comprising:
- receiving, by a first network device, a network packet from a first computing device to be sent over a network to a second computing device connected to a second network device, wherein the network includes the network security device and a network switch, and wherein the network packet includes a first interface identifier that identifies the first computing device as a source of the network packet and a second interface identifier that identifies the second computing device as a destination of the network packet;
translating, by the first network device, the second interface identifier of the network packet to a third interface identifier that identifies an interface connected to the network switch, wherein the network switch is located downstream from the network security device; and
transmitting the network packet from the first network device over the network through the network security device and through the network switch to the interface based on the third interface identifier.

Abstract
A method and a network device are provided to transmit network packets through a network security device. The method, performed by the network device, receives a request to send a network packet from a first computing device to a second computing device over a network that includes the network device and the network security device. The network packet includes a first network interface identifier for identifying the first computing device and a second network interface identifier for identifying the second computing device. The method identifies third and fourth network interface identifiers that cause the network packet to be transmitted through the network security device. The method transmits the network packet over the network through the network security device using the third and fourth network interface identifiers. The method transmits the network packet to the second computing device using the first and second network interface identifiers.

18. A non-transitory computer-readable medium comprising instructions for transmitting network packets through a network security device that when executed cause at least one processor to:
-
receive, by a first network device, a network packet from a first computing device to be sent over a network to a second computing device connected to a second network device, wherein the network includes the network security device and a network switch, and wherein the network packet includes a first interface identifier that identifies the first computing device as a source of the network packet and a second interface identifier that identifies the second computing device as a destination of the network packet; translate, by the first network device, the second interface identifier of the network packet to a third interface identifier that identifies an interface connected to the network switch, wherein the network switch is located downstream from the network security device; and transmit the network packet from the first network device over the network through the network security device and through the network switch to the interface based on the third interface identifier.
