A network architecture includes a perimeter network connected between an internal network and an external network. The perimeter network includes one or more external edge nodes that are connected to the external network and a plurality of proxy servers that are each connected to one or more of the external edge nodes. One or more internal edge nodes are connected between the plurality of proxy servers and the internal network. The proxy servers are operable to establish a first secure connection between a destination through the external network and a second secure connection to a destination in the internal network. Each of the plurality of proxy servers provide a substantially identical identification for authentication when establishing the first and second secure connections.
