Abstract: In some embodiments, a method adds a specific route for an IP address that is associated with a first workload into a routing table for a first network device in a first site in response to the first workload being migrated from a second site to the first site. The first network device receives a packet from a second workload for the first workload and determines that a destination of the packet matches the specific route in the routing table. The method routes the packet from the second workload to the first workload using the specific route in the routing table without sending the packet to the second site.

Abstract: In some embodiments, a first network device in a first site sets a first IP address for an interface of the first network device to a value of a second IP address of a second network device in a second site. Policies are added in a policy table to cover IP addresses used in the second site and a specific route for a third IP address associated with a first workload migrated from the second site to the first site is added into a routing table. The first workload is on a stretched network that is coupled via a layer 2 channel. The policy table configures the first network device to send a second packet from the first workload to a third workload in the second site via the layer 2 channel when an IP address for the third workload does not match an eligible route in the routing table.

Abstract: Embodiments provide a network address translation (NAT) service for network devices. A network connection from at least one private network device to the NAT service is received and a network connection from at least one remote device to the NAT service is received. The private network device is positioned within a private network and the remote device is positioned within a public network. A network availability of the remote device is determined. If the remote device is unavailable or a network configuration setting associated with the remote device changes, the private network device is notified and a connection reset message is transmitted to the private network device.
