Showing RTP stream when there is NAT

Open dovi5988 opened this issue 9 years ago • 1 comments

It seems that the only time sngrep will show rtp is if the IP's in the SDP are where the traffic is coming from. If the UA is behind NAT and sends a local IP in the SDP then it would show up in an active call.

Hi @dovi5988

For 1.4.0, I think the RTP streams are expecting the IP and port described on SDP content or the source IP of the SIP message and the port described on SDP content.

If the RTP packet IP does not match the SDP or the SIP IP addresses, then I guess the UA is the DMZ of the network and this could be duplicate from #115

Are one of this scenarios what you're describing?

Thanks!
