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.
-- Module Size Used by iptable_mangle 12488 0 xt_RTPENGINE 22068 3 iptable_nat 12800 0 nf_nat 17924 1 iptable_nat ... --
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.

This message pops up if there's an unsupported combination of crypto suites or transport protocols being used. I'm not aware of any such combination in the current code base. Can you provide more details about what kind of calls you're handling there?
cheers
For the moment the message appears when a webrtc caller (using chrome v40.0.2214.94 64-bit) dials voicemail service which is running on a legacy sip server. The RTPEngine converts media from SAVPF to AVP for this audio only call.
There may be other scenarios, since this is not the first time i see this message. I will update here when i encounter those scenarios again.
Thank you.

ah ok, looking closely at RTPEngine logs, i also see this message,
-- rtpengine[16455]: [j4ujoo87lsnjvapf4cmd port 41035] SRTCP output wanted, but no crypto suite was negotiated --
So you are right about crypto mismatch, however it is strange why SRTCP was not negotiated with chrome ...
Thank you.

Please do not post the same question to two lists.

I post it on both since i was a bit confused about which list is appropriate for this question.
Anyways, i will toss a coin next time. ;-)
Thank you.
