Hello,

With the wisdom of Alex Balashov we got it running by adding the IP address to the listen-ng parameter.

The question now is how to cure this iptables problem:

Starting RTP/media proxy: rtpengineiptables v1.4.21: unknown option "--id"
Try `iptables -h' or 'iptables --help' for more information.
ip6tables v1.4.21: can't initialize ip6tables table `filter': Address family not supported by protocol
Perhaps ip6tables or your kernel needs to be upgraded.

The iptables module is compiled and installed:

# ls /lib64/xtables/
libxt_RTPENGINE.so

This is on Ubuntu. Any ideas?

Thanks in advance.

Hello,

We're using Kamailio 4.2.1 with rtpengine 5.1.2.1 on Ubuntu 16.04. When running rtpengine we get this error:

[1500263405.711288] ERR: FAILED TO CREATE KERNEL TABLE 0 (File exists), KERNEL FORWARDING DISABLED
[1500263405.712367] CRIT: Fatal error: Failed to open UDP control connection port

The first line I think is not important, but the second appears to be. It's being run as root with these options:

/usr/sbin/rtpengine --interface=xx.xx.xx.xx --listen-ng=7724 --timeout=60 --silent-timeout=3600 --pidfile=/var/run/rtpengine.pid --port-min=45000 --port-max=50000 --table=0

Running "netstat -lnp | grep 7724" does not report anything listening on port 7724 already.

Has anyone any ideas? Thanks in advance.
