Abstract: Some embodiments provide a method for forwarding data messages at multiple edge gateways of a logical network that process data messages between the logical network and an external network. At a first edge gateway, the method receives a data message, having an external address as a destination address, from the logical network. Based on the destination address, the method applies a default route to the data message that routes the data message to a second edge gateway and specifies a first output interface of the first edge gateway for the data message. After routing the data message, the method applies a stored NAT entry that (i) modifies a source address of the data message to be a public NAT address associated with the first edge gateway and (ii) redirects the modified data message to a second output interface of the first edge gateway instead of the first output interface.

Abstract: Some embodiments of the invention provide a method for configuring multiple hardware offload units of a host computer to perform operations on packets associated with machines (e.g., virtual machines or containers) executing on the host computer and to pass the packets between each other efficiently. For instance, in some embodiments, the method configures a program executing on the host computer to identify a first hardware offload unit that has to perform a first operation on a packet associated with a particular machine and to provide the packet to the first hardware offload unit. The packet in some embodiments is a packet that the particular machine has sent to a destination machine on the network, or is a packet received from a source machine through a network and destined to the particular machine.
