To open certain range of ports in your Linux firewall you can do for
example:
-A INPUT -m state --state NEW -m udp -p udp --dport 35000:40000 -j ACCEPT

Depending on how many users you have registering to
your SER you can
change the range of ports served by rtpproxy.
Default is 35000-65000 and this can be changed in rttp_defines.h and
recompile
your rtpproxy. Then you can open just ports on your firewall as it is
defined in.
rttp_defines.h.

I apologize for my former question. It was just a firewall issue on
the computer running rtpproxy. I didn’t open the right ports L
But is it possible to configure rtpproxy to open ports automatically
on firewalls, instead of opening a huge number of ports manually?

*Objet :* [Serusers] Rtpproxy: media not forward
Dear all,
I have installed rtpproxy from
http://www.openser.org/downloads/snapshots/rtpproxy/rtpproxy-cvs-latest.tgz
on the same computer as Openser.
I started it without options. /var/run/rtpproxy.pid and .sock are
created.
I suppose a communication is established between OpenSer and Rtpproxy
as SDP messages are correctly replaced, it means “Connection
Information c” shows rtpproxy IP address and ports.
Also both UAs sent RTP media to rtpproxyIP:port described in SDP
body, but rtpproxy doesn’t forward any RTP packets from one UA to the
other.
Tcpdump –n udp and host 213.48.xxx.yyy result:
11:48:49.191130 IP 213.48.xxx.yyy.2236 > 207.245.aaa.bbb.35000: UDP,
length 60
11:48:49.250183 IP 213.48.xxx.yyy.2236 > 207.245.aaa.bbb.35000: UDP,

11:48:49.297275 IP 213.48.xxx.yyy.2237 > 207.245.aaa.bbb.35004: UDP,
length 60
11:48:49.335890 IP 213.48.xxx.yyy.2237 > 207.245.aaa.bbb.35004: UDP,
length 60
11:48:49.339723 IP 213.48.xxx.yyy.2236 > 207.245.aaa.bbb.35000: UDP,
length 60
11:48:49.393997 IP 213.48.xxx.yyy.2237 > 207.245.aaa.bbb.35004: UDP,
length 60
Have you ever come across that issue? How can I get
207.245.aaa.bbb.35000 > 213.48.xxx.yyy.2237? Does this problem occur
because both UAs are in the same local network? (I don’t thing so)
I would be very thankful if you could give me an idea about it.
Thanks a lot
Paul
