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

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.
