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 provide a method for deploying edge forwarding elements in a public or private software defined datacenter (SDDC). For an entity, the method deploys a default first edge forwarding element to process data message flows between machines of the entity in a first network of the SDDC and machines external to the first network of the SDDC. The method subsequently receives a request to allocate more bandwidth to a first set of the data message flows entering or exiting the first network of the SDDC. In response, the method deploys a second edge forwarding element to process the first set of data message flows of the entity in order to allocate more bandwidth to the first set of the data message flows, while continuing to process a second set of data message flows of the entity through the default first edge node.

Abstract: Some embodiments provide policy-driven methods for deploying edge forwarding elements in a public or private SDDC for tenants or applications. For instance, the method of some embodiments allows administrators to create different traffic groups for different applications and/or tenants, deploys edge forwarding elements for the different traffic groups, and configures forwarding elements in the SDDC to direct data message flows of the applications and/or tenants through the edge forwarding elements deployed for them. The policy-driven method of some embodiments also dynamically deploys edge forwarding elements in the SDDC for applications and/or tenants after detecting the need for the edge forwarding elements based on monitored traffic flow conditions.

Abstract: Described herein are systems, methods, and software to manage secure tunnel communications in multi-edge gateway computing environments. In one implementation, a control system identifies an edge gateway from a plurality of edge gateways to support a private network tunnel. The control system further identifies addressing attributes associated with communications directed over the private network tunnel and configures the plurality of edge gateways to forward packets associated with the addressing attributes to the identified edge gateway, wherein the edge gateway can process and forward the packets over the private network tunnel.

Abstract: Many hybrid cloud topologies require virtual machines in a public cloud to use a router in a private cloud, even when the virtual machine is transmitting to another virtual machine in the public cloud. Routing data through an enterprise router on the private cloud via the internet is generally inefficient. This problem can be overcome by placing a router within the public cloud that mirrors much of the routing functionality of the enterprise router. A switch configured to intercept address resolution protocol (ARP) request for the enterprise router's address and fabricate a response using the MAC address of the router in the public cloud.
