Method for establishing secure communication link between computers of virtual private network

A computer-readable storage medium, comprising:

• a storage area;
• and
• computer-readable instructions for a method for communicating using a private communication link between a client computer and a server computer over a computer network, the method comprising steps of:
• sending an information packet from the client computer to the server computer over the computer network, the information packet containing data that is used for forming a virtual private connection between the client computer and the server computer, the data that is used for forming the virtual private connection being inserted into a payload portion of the information packet at the client computer by an application layer program;
• receiving the information packet at a kernel layer of an operating system on the server computer;
• and
• determining at the kernel layer of the operating system on the server computer whether the information packet contains the data that is used for forming the virtual private connection.

A method for communicating using a private communication link between a client computer and a server computer over a computer network, the method comprising steps of:

• generating an information packet at the client computer,
• modifying the information packet at an application layer within the client computer by inserting data into a payload portion of the information packet that is used for forming a virtual private connection between the client computer and the server computer;
• and
• sending the modified information packet from the client computer to the server computer over the computer network.
