The GeNUBox allows access to machines in customer networks by external remote without compromising network security. – Elimination of a direct dial into the customer network, no direct firewall opening – Only access to a Rendezvous Server in a Demilitarized Zone (DMZ) beside the main firewall – Rendezvous Server is realized with GeNUBox – For remote access, the service provider builds a remote SSH tunnel to the Rendezvous Server – Only when the administrator of the customer network builds another tunnel from the second GeNUBox at the maintenance object to the Rendezvous Server, the service provider has access to the maintenance object.
