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.
