Some embodiments provide a method that transmits network packets through a network security device. The method receives receiving a request to send a network packet from a first computing device to a second computing device over a network that includes the network security device. The network packet includes a first network interface identifier for identifying the first computing device on the network and a second network interface identifier for identifying the second computing device on the network. The method identifies third and fourth network interface identifiers that cause the network packet to be transmitted through the network security device when the network packet is transmitted using the third and fourth network interface identifiers. 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.
