Abstract: This invention is an improved system and method of efficiently deploying a large scale roll out of secure networks, including a VPN, to clients with limited or non-existent technical staff. The invention allows for a person with minimal technical skills to install, and, if necessary, uninstall the solution. Through a series of automated and/or remotely-controlled steps provided through connections established from inside the site to a centralized system over an unprotected network, the site's network can be secured, updated, and/or reconfigured, and returned to its previous state if errors should occur. Furthermore, a virtual private network (VPN) can be established that allows multiple hosts on the VPN but on different local networks to have the same IP address.
