Abstract

Some embodiments provide a method for a network controller that manages a logical network implemented in a datacenter comprising forwarding elements to which the network controller does not have access. The method identifies a data compute node (DCN), that operates on a host machine in the datacenter, to attach to the logical network. The DCN has a network interface with a first network address provided by a management system of the datacenter, and executes (i) a workload application and (ii) a managed forwarding element (MFE). The method distributes configuration data for configuring the MFE to receive data packets sent from the workload application on the DCN and perform network security and forwarding processing on the data packets. The data packets sent by the workload application have a second network address as a source address when received by the MFE and are encapsulated by the MFE using the first network address.
