ABSTRACT:
A system, apparatus and a method for implementing a secured communications link at a layer other than that at which packets are filtered are disclosed. In one embodiment, a computer system is configured to form a virtual private network (“VPN”) and comprises an address inspection driver to identify initial target packet traffic addressed to a target server. Also, the computer system includes a pseudo server module to receive rerouted initial target packet traffic from the address inspection driver. The pseudo server module is configured to convey packet regeneration instructions to a VPN gateway. The address inspection driver functions to identify additional target packet traffic addressed to the target server and routes the additional target packet traffic to the pseudo server. In one embodiment, the pseudo server is configured to strip header information from the additional target packet traffic to form a payload, and thereafter, to route the payload to the target server.
