Some embodiments provide a network system. The network system includes a first set of host machines for hosting virtual machines that connect to each other through a logical network. The first set of host machines includes managed forwarding elements for forwarding data between the host machines. The network system includes a second set of host machines for hosting virtualized containers that operate as gateways for forwarding data between the virtual machines and an external network. At least one of the virtualized containers peers with at least one physical router in the external network in order to advertise addresses of the virtual machines to the physical router.

Some embodiments provide a novel method for load balancing data messages that are sent by a source compute node (SCN) to one or more different groups of destination compute nodes (DCNs). In some embodiments, the method deploys a load balancer in the source compute node's egress datapath. This load balancer receives each data message sent from the source compute node, and determines whether the data message is addressed to one of the DCN groups for which the load balancer spreads the data traffic to balance the load across (e.g., data traffic directed to) the DCNs in the group. When the received data message is not addressed to one of the load balanced DCN groups, the load balancer forwards the received data message to its addressed destination. On the other hand, when the received data message is addressed to one of load balancer's DCN groups, the load balancer identifies a DCN in the addressed DCN group that should receive the data message, and directs the data message to the identified DCN. To direct the data message to the identified DCN, the load balancer in some embodiments changes the destination address (e.g., the destination IP address, destination port, destination MAC address, etc.) in the data message from the address of the identified DCN group to the address (e.g., the destination IP address) of the identified DCN.

Some embodiments provide a central firewall management system that can be used to manage different firewall devices from a single management interface. This management interface provides a uniform interface for defining different firewall rule sets and deploying these rules sets on different firewall devices (e.g., port-linked firewall engines, firewall service VMs, network-perimeter firewall devices, etc.). Also, this interface allows the location and/or behavior of the firewall rule sets to be dynamically modified. The management interface in some embodiments also provides controls for filtering and debugging firewall rules.

Some embodiments provide a network system. The network system includes a first set of host machines hosting virtual machines that connect to each other through a logical network. The network system includes a second set of host machines hosting virtualized containers that operate as gateways to process packets entering the logical network from external sources. Each of the virtualized containers advertises itself to an external router as a next hop for packets entering the logical network such that the external router uses equal-cost multi-path forwarding to distribute the packets across the virtualized containers on the second set of host machines.
