RTSP streaming got "udp port unreachable"

Wowza Streaming Engine
1

Hi,

I’m currently doing a live application with RTSP streaming, i notice that RTSP only works when rtp over tcp. With rtp over udp, i got that message when i use tcpdump: “ICMP x.x.x.x udp port 6974 unreachable”. As i know “udp port unreachable” means the host does not listen on that port. Then i try netstat to find which port wowza is listenning, i cannot see any udp port, but i see this line in log file “RTPUDPTransport.bind[live/definst]: in:0.0.0.0/0.0.0.0:6974”.

So did i do something wrong?

Thanks,

Huy.

Hi,

I think that it’s belongs to my load balancer problem, in my real server i have a VIP and real IP, I see that when wowza server sends udp data to client, it uses real IP, but client send RTCP status to VIP, can it be the cause of my problem?

And i do not know why wowza use real IP instead of VIP, because in this server i also deployed a Darwin Streaming server, it worked well with my load balancer and use VIP when sending udp data to client.

Any help would be appreciated, thanks!
