Abstract
A system and method for providing multiple virtual private networks from a computer system. The computer system communicates with a remote computer system in order to allow encrypted data traffic to flow between the respective systems. Two phases are used to authenticate the computer systems to one another. During the first phase, digital certificates or pre-shared keys are used to authenticate the computer systems. A phaseID rules list contains authentication rules for local-remote computer pairs. During the second phase, a hash value is used to authenticate the computer systems and a security association payload is created. The remote system's IP address is used for connecting. The phaseID rules list corresponds to one or more phaseID rules lists. If the remote ID is not found in the phaseID rules list, a default rule is used based upon the phaseID rules list.
