Hai Everyone.
I have configured the RTP Proxy with Kamailio SIP Proxy Server.
Where I have my Kamailio is configured with private IP 10.0.0.1 and Public UP 103.XX.XX.XX
and the SIP user is connecting with RTP proxy with local IP 10.0.0.1 to register.
I also have a SIP Asterisk server on the public Internet with IP 90.XX.XX.XX that makes the call to sipuser@103.XX.XX.XX:5060 which is coming on the sip proxy server and the sip proxy server forwards those packets to the SIP user who is registered with local IP 10.0.0.5.
Once the call is answered the RTP is started to send from the SIP server to the SIP Proxy server over the public IP from 90.XX.XX.XX to 103.XX.XX.XX which is working as expected. But from the sip user 10.0.0.5 the RTP is flowing to Proxy server public IP 103.XX.XX.XX instead of RTP Proxy server Localip 10.0.0.1.
How can we configure the same?
Presently I have started my RTP proxy server with command
/usr/local/bin/rtpproxy -F -A 103.XX.XXXX -l 10.0.0.1 -m 10000 -M 20000 -s udp:127.0.0.1:7722 -d DBUG:LOG_LOCAL5
Thanks in advance.

Take a look at bridge mode for rtpproxy. You'll want an internal side for NAT and an external side for using the public IP.

… and always consider whether your use of rtpproxy is intentional, or whether you just overlooked RTPEngine…
