Hi Ross,
We are using Amazon Server having public and private ip addresses for their
server instances. There is no NAT on Amazon or on our Client side. our Client
also has the public IP address.
By default with live555, when RR reports are sent from testRTSPClient using
UDP, the destination of the RR report is the private IP address of the amazon
server instead of public IP. client gets this private IP address from the SDP
sent by the live555 server in response to DESCRIBE command. We want to change
it to public IP address because our server has the public IP address as well.
Just for testing, we changed the live555 library function as below and RR
reports work fine.
void MediaSubsession::setDestinations(netAddressBits defaultDestAddress) {
netAddressBits destAddress = connectionEndpointAddress(); //BY DEFAULT THIS
FUNCTION RETURNS PRIVATE IP OF THE AMAZON SERVER INSTANCE
if (destAddress == 0) destAddress = defaultDestAddress;
struct in_addr destAddr; destAddr.s_addr = destAddress;
//-----------------------------------------
destAddr.S_un.S_un_b.s_b1=AA; // //AA.BB.CC.DD IS THE PUBLIC IP OF THE
SERVER WE CHANGED HERE WITH THIS IP
destAddr.S_un.S_un_b.s_b2=BB;
destAddr.S_un.S_un_b.s_b3=CC;
destAddr.S_un.S_un_b.s_b4=DD;
//-----------------------------------------------
What we want is that when RR packets are sent, the destination address should
be the public IP of the server not its private, we don't want to make change in
the library method as the way we did in above code. what should we do in this
case?
Best Regards
Mohsin

UDP
It wasn’t totally clear from your message, but you seem to be implying that
there is a NAT between your server and your client - with your server on the
public Internet, and your client in a private IP address space (i.e., behind a
NAT).
In general, you *cannot* expect RTP/RTCP/RTSP streaming to work in such an
environment (because RTSP ***was not designed to work across NATs***).
For RTSP to work reliably, both the server and client(s) should all be on the
public Internet (or all on the same private Internet). Sorry.
