[SR-Users] Can rtpproxy be used withou NAT ?

Hi mailing, I installed kamailio 3.2, rtpproxy 1.2.1, callcontrol 2.0.15 on a vz, and cdrtool 8.2.5 and freeradius 2.1.10 on another vz. The 2 vz container have public ip address, and the UAC have private ip address. I want to use rtpproxy, and the following are what ps and netstat command returns about rtpproxy: teddy@kamailio:~$ ps aux | grep rtpproxy teddy 22866 0.0 0.0 3312 800 pts/0 S+ 11:08 0:00 grep rtpproxy teddy 31326 0.0 0.0 11360 804 ? Ssl Apr06 0:02 /usr/sbin/rtpproxy -F -l our_public_ip -s udp:localhost 22222 teddy@kamailio:~$ sudo netstat -pln | grep rtp udp 0 0 127.0.0.1:22222 0.0.0.0:* 31326/rtpproxy And my problem is: when I make calls, for example the UAC1 calls UAC2, with ngrep I see the UAC1 calls UAC1 and not UAC2, and I don't know why. In kamailio config file, there are directive WITH_NAT for everything related to rtpproxy (loadmodule, routing logic, etc) as you can see in the attached conf file. I try disable the use of this directive WITH_NAT so I disable the use of rtpproxy in kamailio and it works: when UAC1 calls UAC2, the UAC2 is ringing. Please tell me what am I doing wrong, or to use rtpproxy without NAT is not possible ? In attached file the kamailio config file, the diff between rtpproxy enable and rtpproxy disable, and the result of ngrep and what is in syslog when I made calls. Thanks in advance. -- Rabary Teddy Inutile d'imprimer ce mail
