here is the scenario:

kamailio 4.0.4 running in bridge mode 

eth0 : 10.17.0.202

eth1 : 100.200.30.40

a call comes in from ice enabled webrtc client (chrome) from public internet, 

kamailio processed the call, no audio.

if i replace kamailio with asterisk, audio ok.

upon investigating using wireshark, i found out that chrome sends a "Binding Request" for the IP/port in ICE candidate. Kamailio/rtpproxy sends back

Binding Success XOR-MAPPED-ADDRESS but the IP is the internal one 10.17.0.202:port

this is not right, the response should be the remote IP/port, not the local IP/port
