Method for deploying a firewall and virtual private network to a computer network

摘要

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. Additionally, without any additional hardware and as part of the installation process, the invention protects the site from unauthorized local network devices either by preventing them from passing traffic off the local network or by generating notification of their existence.
