[SR-Users] Cannot run Kamailio on public IP

[spamasbl at gmail.com]

Thank you, Klaus for your prompt reply.

Now Kamailio listens on local IP (192.168.1.137)
I've added advertised_address line into my conf (I've added here my public
hostname)
Also I have configured RTPProxy on port 22222, and now Kamailio starts
without errors or
warnings:
Apr 7 04:58:37 sipbox kamailio[2465]: INFO: rtpproxy [rtpproxy.c:1403]: rtp
proxy <udp:127.0.0.1:22222> found, support for it enabled

But still the problem persists. I am not able to register with kamailio via
public IP.

DMZ is turned on, so I guess router should forward all ports to .137
address.

When trying to register, I am getting request timed out.

Any ideas ?

Thanks
