I did try rtpengine_manage() but rtpengine still saves 10.0.0.100 in redis. I did also try without asymmetric with no luck.
I changed flags in my rtpengine_answer() and rtpengine_offer() to "replace-session-connection replace-origin" that saved the public ip correctly and forwarded SDP correctly. The call is now established
Now I have problem when the remote user B-end hangs up. Why would kamailio 188.166.3.25 just send the BYE message back to 188.226.200.111 instead of sending it to 80.71.132.X A-end behind NAT? (the last 4 packeges in the dump)
The problem must be aroung t_relay() ?
Cheers, Martin

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.
