I thought that "fix_nated_sdp("2")" would do the job before "rtpengine_offer("asymmetric")" but it dosen't have any effect?

My understanding of the docs is that the asymmetric flag introduces the problem you are experiencing: asymmetric - flags that UA from which message is received doesn't support symmetric RTP. Disables learning of endpoint addresses in the Sipwise rtpengine proxy.

Getting rtp_engine to work with the standard kamailio.cfg is to simply add rtpengine_manage(); at the top of the NATMANAGE route so it will handle all rtp regardless of source being natted (in your config in the NAT router.
