Hi Carsten....Congrats on getting your router set-up and connected to CyberGhost! I must admit, that's farther than I've been able to get and CyberGhost support is non-existent. I keep getting stuck on some sort of TLS Time-out error.
Did you have this problem and how where you able to get round it please. More details of my current set up are here...
