Abstract
Disclosed is a system and method for enhancing the security and reliability of virtual private network (VPN) connections by manually exchanging secondary configuration information. If a compromise is detected on a main VPN tunnel, a new VPN tunnel can be created by the system administrators using the secondary configuration, stymieing attempted security violations and providing nearly continuous service to the users. A compromise may be indicative of a security breach or other problem with the VPN. The main VPN tunnel may be abandoned or fed with false data to confuse would-be intruders if the compromise is a security compromise.
