Software implemented virtual private network service

摘要

A method and system for implementing a virtual private network utilizes a single public IP address and avoids the use of a firewall. The method includes having a router in a private network perform one-to-one mapping of a public IP address to a private IP address such that a firewall, and the additional public IP address typically used to access the firewall, are not used. The system comprises a router having instructions for one-to-one mapping of a public IP address to a private IP address and does not include a firewall.
