Icam with remote fallback

How can I also receive Sky De channels using icam on a client receiver connected to another receiver with remote fallback? Obviously I installed oscam+icam on the master receiver and I see both oscam and icam (Sky De) channels, while on the client I only see the oscam channels. Obviously I changed all the lines dedicated to the channels in the icam.tv file going from http%3a//127.0.0.1%3a17999 to http%3a//192.168.36.8%3a9123 where 192.168.36.8 is the IP address of the master receiver and 9123 is the port set to communicate. It tunes the channel but does not decode it. What am I doing wrong?
