The first server (srv1-in1) acts as a gateway while the second one is acting as a UE computing platform (to which a UE modem is attached). The 5G Platform devices and the nodes are connected to the sandbox 1 data 1 network and rel ies on IP routing to ensure that the traffic flow from the client follows the dashed red line in the figure.
