摘要： Network traffic inspection is disclosed. An application executing on a client device as an operating system that uses a virtual private network (VPN) stack of the operating system intercepts a first IP packet. The application determines that a policy should be applied to the intercepted first IP packet. The policy is applied to the intercepted first IP packet.

摘要： Techniques for inspecting network traffic are disclosed. An application executing as an operating system extension that uses a virtual private network (VPN) stack of the operating system intercepts an Internet protocol (IP) packet for delivery to a remote computer system. A determination is made of an alteration action to take in response to intercepting the packet. The determined action is taken.

摘要： A reverse TCP/IP stack infrastructure is disclosed. In an example use, an application executing on a client device as an operating system extension that uses a virtual private network stack of the operating system intercepts a first IP packet generated by a client program. The application determines that the first IP packet comprises a Transmission Control Protocol synchronize message and opens a socket to a destination Internet Protocol address and destination port. A synchronize acknowledgement is received. A packet to transmit to the client program is synthesized that includes a synchronize acknowledgment.
