Hello,

Hi Daniel
For my needs i installed rtpengine also.
To be sure rtpengine in kernel forwarding mode I configured

systemd unit file

[root@ip-44-230-120-21 ~]# cat /etc/systemd/system/rtpengine.service
[Unit]
Description=NGCP RtpEngine - RTP Media Proxy
Wants=network-online.target
After=network-online.target

[Service]
Type=simple
ExecStart=/usr/sbin/rtpengine -f
ExecStartPost=/sbin/iptables -I INPUT -p udp -j RTPENGINE --id 0
ExecStartPost=/sbin/ip6tables -I INPUT -p udp -j RTPENGINE --id 0
ExecStopPost=-/sbin/iptables -D INPUT -p udp -j RTPENGINE --id 0
ExecStopPost=-/sbin/ip6tables -D INPUT -p udp -j RTPENGINE --id 0
Restart=on-failure

[Install]
WantedBy=multi-user.target

And inside /etc/rtpengine/rtpengine.conf I defined "no-fallback = true"

With "no-fallback = true" rtpengine wont start if kernel module not available.

This is just to be sure it starts only with kernel module and in-kernel forwarding mode, right? So you do not want at all userspace forwarding, better fail than being less performant.

Cheers,
Daniel

Thanks for clarifying its status!

Cheers, Daniel
