Abstract
The invention features a method for enabling computers to communicate using encrypted network packets. A configuration request is sent over a network from a first computer to a second computer, and tunnel record information is sent over the network from the second computer to the first computer. The tunnel record information is encrypted in accordance with a temporary configuration password. The invention also features a method for updating a tunnel record. A connection request is sent from a first computer to a second computer, and the first computer is authorized. A tunnel record corresponding to the connection request with the first computer's network address is then updated.
