Abstract

Systems, methods and apparatus for tunneling in a cloud based security system. A multi-tenant cloud-based security system that can distinguish between client computing devices with overlapping private IP addresses is disclosed. Client devices communicate through a processing node to which a tunnel is established. The processing node is able to detect the client devices and apply security policies to the device.
