In order for the transmission to the Internet to work, the Server-PC needs a "Port Forwarding". To-do
this, open the router, go to Internet -> Release and release ports 50071 to 50073 (data and audio) on
the Server-PC via TCP and UDP. Then open "ExpertRC" on the Client-PC, select Options -> Device and
enter the public IPv4 address of the router and the port of the SunSDR2 DX, in the example:
92.36.144.213:50071 (Fig. 8).
