Abstract
System, device, and method of deploying layer-3 transparent cloud-based proxy network element. A virtual network function is defined between a west-side router and an east-side router. A west-side interface receives east-bound traffic from a west-side Virtual LAN. East-bound queries from the west-bound router, are intercepted and responded to by the west-side interface, the response indicating the MAC address of the west-side router instead of the east-side router. The system enables the virtual network function to transparently intercept network traffic, and to selectively apply to such traffic one or more network functions or operations, prior to forwarding the traffic or a modified version thereof to the east-side router, in a Layer-3 transparent manner.
