Zusammenfassung:	Embodiments relate to enabling clouds to multiplex their public network addresses among private addresses of IPSec gateways while making sure that IPSec tunnel packets are delivered to the private addresses of the IPSec tunnels that they are associated with. When IPSec packets egress from a cloud, the cloud may determine which IPSec tunnel or gateway the IPSec packets are associated with and modify the IPSec packets to identify the associated tunnel or gateway. When IPSec packets ingress to the cloud, the cloud may find identity information in the IPSec packets that identifies the associated tunnel or gateway. The identity information is used to direct the IPSec packets to the associated tunnel or gateway.
