[OpenSIPS-Users] RTPPRoxy behind NAT

[Nick Chang]

Hello Sammy

 

No, I don't forget.

 

My rtpproxy's  startup script is "/usr/local/bin/rtpproxy -l
111.22.33.44/10.1.2.103 -s udp:10.1.2.103 19999 -F -m 36000 -M 36010 -d
DBUG"

I have forwarded the 36000~36010 port to rtpproxy server.

 

Firewall  -----------------------  Opensips/rtpproxy Server

111.22.33.44:5060                       10.1.2.103:5050

111.22.33.44:36000/36010         10.1.2.103:36000/36010

But, Now sometime no audio.  

Do you have any suggest

Thanks

Nick

Hi Nick,
So you've forwarded the 5060 port to opensips server, cool. Did you forget
to mention about the RTP ports forwarded to server ? 
Start RTPproxy with param -m and -M to assign range of RTP ports to use.
Then forward that UDP port range to opensips server too.
Then see what happens with audio.
Also what is your total voip diagram with their network addresses. 

Thanks,
Sammy

My NAT type is Full cone NAT.

 

In Firewall, I setting a IP & port 5060 to LAN IP.

 

Example:

 

Firewall  -----------------------  Opensips Server

111.22.33.44:5060                       10.1.2.103:5050

 

Thanks

Nick
