1. A computer network comprising:
a Non-Internet Protocol (IP) subnetwork with at least one frontend device;
an IP subnetwork with at least one backend device;
a gateway connecting the Non-IP subnetwork with the IP subnetwork and translating communication therebetween, wherein the communication between the backend device and the gateway is an IP communication based on an IP security protocol, providing means for authentication and/or encryption; and
wherein the communication between the gateway and the frontend device is a Non-IP communication;
wherein the gateway is configured to provide a virtual IP communication endpoint, dedicated to the frontend device, wherein for establishing a secure end-to-end communication between the backend device and the frontend device, the gateway is configured such that upon receipt of a request datagram with a header specifying the backend device as source and the virtual IP communication endpoint as destination, the Non-IP communication is applied to transmit a transcription of the request datagram to the frontend device; and
wherein the frontend device is configured to generate a response datagram and to transmit a transcription of the response datagram to the gateway by applying the Non-IP communication; wherein the frontend device is configured to run an implementation of the IP security protocol such that the frontend device is capable to interpret the transcription of the request data datagram.
