Abstract: A physical host machine of a public cloud system includes a set of processing units for executing instructions stored in non-transitory machine readable media. The physical host machine also includes a physical network interface cars (PNIC) and a non-transitory machine readable medium that stores a data compute node (DCN). The DCN includes first and second applications, first and second logical interfaces, a network stack, and a managed forwarding element (MFE). The first application is connected to the pNIC through the network stack, the first logical interface, and the MFE. The second application is connected to the PNIC through the network stack, the second logical interface, and the MFE.

Abstract: A data compute node executes (i) a set of tenant applications connected to a third party overlay network, (ii) a set of network manager applications, and (iii) a managed forwarding element that includes a pair of overlay and underlay network virtual adapters. A packet that is received from a network manager application and addressed to an underlay network destination is sent to the underlay network destination address through a physical NIC of the host without network address translation or encapsulation. A packet that is received from a tenant application and addressed to an underlay network destination is subject to SNAT and is sent to the underlay network destination address. A packet that is received from a tenant application and is addressed an overlay destination address is encapsulated with the header of the overlay network and is sent to the overlay network destination address through the underlay virtual adapter.
