Abstract
A virtual private network is disclosed including a first firewall interposed between a first private network and a public network, and a second firewall interposed between a second private network and the public network. An encrypted path is provided for traffic flowing between the first and second firewalls. A dedicated domain name server is also provided and is associated with each of the first and second firewalls for establishing DNS mappings for the virtual private network. Either of the firewalls may block traffic if content is found to be objectionable.
