Hi everyone, I'm running kamailio and rtpproxy on the same server behind a NAT.

I start the deamon using command: rtpproxy -A 35.185.130.154 -F -l 10.240.0.62 -m 35000 -M 65000 -s udp:*:64000 -d INFO

When two sip clients call each other, the rtpproxy syslog shows that a rtp session has been established successfully.

rtpp_command_ul_handle: new session on IPv4 port 56340 created ... ... rtpp_command_ul_handle: lookup on ports 56340/44468, session timer restarted

but the two clients have no audio. And I can noly capture RTCP packets on the server, NO RTP packet.

sudo tcpdump -i eth0 udp port 56340 -vv -X

0 packets captured 0 packets received by filter 0 packets dropped by kernel

sudo tcpdump -i eth0 udp port 56341 -vv -X

Am I missing something in the config? Appreciate it if anyone could help.
