Hi,

I have latest stable release of RTPEngine deployed in a virtual machine (KVM) along with Kamailio v4.2. All is working fine except i see this message in RTPEngine logs,

--
rtpengine[16455]: [82qrjq0hdtt45afbqo98 port 40960] Kernelizing media stream
rtpengine[16455]: [82qrjq0hdtt45afbqo98 port 40960] No support for kernel packet forwarding available
--

using lsmod command i see that module xt_RTPENGINE is load.

Also the iptables rule for RTPEngine exists, i.e.

--
Chain INPUT (policy ACCEPT 224K packets, 37M bytes)
pkts bytes target     prot opt in     out     source               destination
224K   37M rtpengine all -- any    any     anywhere             anywhere

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target     prot opt in     out     source               destination

Chain OUTPUT (policy ACCEPT 224K packets, 37M bytes)
pkts bytes target     prot opt in     out     source               destination

Chain rtpengine (1 references)
pkts bytes target     prot opt in     out     source               destination
2022 414K RTPENGINE udp -- any    any     anywhere             anywhere             RTPENGINE id:0

Yet still RTPEngine is not able to kernelize the RTP stream and does user-space packet forwarding? Can you guys suggest what could be wrong here?

Thank you.
