Ok i will check the flags, I set the domain parameter of rtpproxy_offer to PUBLIC_IP, i create the rules in my router to bind the ports 35000 to 35200 of the public_ip to the ports 35000 to 35200 in the PRIVATE_IP of rtpproxy 192.168.1.220, I'm not sure if this is correct.
If i don't put the domain parameter in the rtpproxy_offer the SDP message contains the private ip of the RTPPROXY (192.168.1.220) and my clients are outside this nat.
