Hi ,
Could anybody please give me the approach how to configure NAT in kamailio IMS.
I have installed kamailio IMS in openstack environment which has private ips for all four vms (each component in one vm). pcscf has one floating IP attached. I have enabled "WITH_NAT" and configured rtpproxy .
when i make a call from outside of openstack using 2 zoiper clients with outbound proxy keeping floating ip of pcscf, I am getting 200 ok with all SIP packets correctly flowing but there is no RTP Packet.
When i try the same within openstack environment without using public ip, I am getting RTP Packets.
Kindly tell me the procedure of NAT Enablement or do i need to do anything other than this.
Kindly help because i am stuck with this for long time.
Thanks.
Hello Pavithra,
Have you tried advertising the floating IP of the VM running RTPProxy as follows?
Edit /etc/default/rtpproxy file as follows:
# Additional options that are passed to the daemon. EXTRA_OPTS="-l 172.24.15.30 -d DBUG:LOG_LOCAL0"
here, "-l <PUBLIC_IP>"
Hope it helps.

Hi ,
Yes I have configured as you mentioned only . In my pcscf only i have rtpproxy also configured. Floating IP i have given in listen address also as listen = 10.40.10.3:4060 advertise 10.45.4.22:4060
10.40.10.3 - private ip 10.45.4.22 - floating ip Still RTP alone is not coming.
Is it the only way of configuring NAT ?
Thanks.

Also check the SDPs and make sure you get the internal up of rtpproxy on the internal side, and the external on the external side.

Hi ,
I also have a doubt like whether rtpproxy is mandate for NAT traversal. Without that RTP between two sip clients.. Is it not possible here ? Kindly clarify.. since i am new to this kamailio ims.

Hi Supreeth,
I have kamailio ims installed in 4 vms inside openstack.
10.40.10.3 - pcscf in port 4060 (pcscf with NAT enabled in pcscf.cfg (!#define WITH_NAT) and configured rtpproxy) 10.40.10.12 - icscf in port 4070 10.40.10.5 - scscf in port 4080 10.40.10.30 - hss
so all these vms are running in same subnet. I have a floating ip associated to pcscf. Now I have two zoiper clients outside openstack zoiper1 - 10.0.2.15 (NAT Enabled Network adaptor) zoiper2 - 10.0.2.15
when i am making a call from zoiper1 to zoiper2, call is going properly . SIP messages are coming properly in wireshark packets. when i filter for RTP packets in wireshark, it is not coming.
when i have the zoiper clients inside openstack itself ,i can able to see RTP Packets in wireshark between two sip clients without any NAT related configurations done.
Kindly help me. Thanks.

Thanks for the pcap. Sorry, to ask this but can you also send pcap of scenario where you see RTP packets?
Also, did you restart the rtpproxy after altering the /etc/default/rtpproxy ?
i.e.
$ systemctl restart rtpproxy

Hi Pavithra,
Thanks for the clarification. Can you please attach a pcap of the call where you are not seeing the RTP packets? And, btw is the call getting dropped or something in that scenario?

Hi Supreeth,
I have kamailio ims installed in 4 vms inside openstack.
10.40.10.3 - pcscf in port 4060 (pcscf with NAT enabled in pcscf.cfg (!#define WITH_NAT) and configured rtpproxy) 10.40.10.12 - icscf in port 4070 10.40.10.5 - scscf in port 4080 10.40.10.30 - hss
so all these vms are running in same subnet. I have a floating ip associated to pcscf. Now I have two zoiper clients outside openstack zoiper1 - 10.0.2.15 (NAT Enabled Network adaptor) zoiper2 - 10.0.2.15
when i am making a call from zoiper1 to zoiper2, call is going properly . SIP messages are coming properly in wireshark packets. when i filter for RTP packets in wireshark, it is not coming.
when i have the zoiper clients inside openstack itself ,i can able to see RTP Packets in wireshark between two sip clients without any NAT related configurations done.
Kindly help me. Thanks.

Hi ,
Yes I have configured as you mentioned only . In my pcscf only i have rtpproxy also configured. Floating IP i have given in listen address also as listen = 10.40.10.3:4060 advertise 10.45.4.22:4060
10.40.10.3 - private ip 10.45.4.22 - floating ip Still RTP alone is not coming.
Is it the only way of configuring NAT ?
Thanks.

Hello Pavithra,
Have you tried advertising the floating IP of the VM running RTPProxy as follows?
Edit /etc/default/rtpproxy file as follows:
# Additional options that are passed to the daemon. EXTRA_OPTS="-l 172.24.15.30 -d DBUG:LOG_LOCAL0"
here, "-l <PUBLIC_IP>"
Hope it helps.

HI,
Hold on a moment,
10.40.10.3 - pcscf in port 4060 (pcscf with NAT enabled in pcscf.cfg (!#define WITH_NAT) and configured rtpproxy) 10.40.10.12 - icscf in port 4070 10.40.10.5 - scscf in port 4080 10.40.10.30 - hss
So i assume you are using the examples provided in the ims folder of kamailio repo right? Isn't it using RTPEngine and not RTPProxy? Or have you modified the P-CSCF configuration to work with RTPProxy?

Hi ,
I didn't configure rtpengine ..instead of that only I used rrpproxy..will it not work?
If not please tell me how to configure rtpengine and also tell me if it is really madatory .. why can't we have sip client to sip client rtps flowing like how it is happening without NAT.
That's my doubt ..please clarify ..
Thanks.

Hello Pavithra,
I have written a guide for how to integrate an IMS using Kamailio with open5gs EPC, here is the link https://open5gs.org/open5gs/docs/tutorial/02-VoLTE-setup/. You can find steps to setup rtpengine in that guide.
Regarding requirement of rtpengine, its mandatory if you want to use the scripts in that example folder without modification. Also, read the READE of sipwise/rtpengine github repo, its very informative (in a gist rtpengine offer much more feature than rtpproxy)
why can't we have sip client to sip client rtps flowing like how it is
happening without NAT.
For this, i would definitely suggest to read about SIP working. This is a perfect link https://github.com/onmyway133/blog/issues/284 which offers extensive material (short and very interesting to read with examples) related to SIP.
Best Regards, Supreeth

HI,
Hold on a moment,
10.40.10.3 - pcscf in port 4060 (pcscf with NAT enabled in pcscf.cfg (!#define WITH_NAT) and configured rtpproxy) 10.40.10.12 - icscf in port 4070 10.40.10.5 - scscf in port 4080 10.40.10.30 - hss
So i assume you are using the examples provided in the ims folder of kamailio repo right? Isn't it using RTPEngine and not RTPProxy? Or have you modified the P-CSCF configuration to work with RTPProxy?

Hi supreeth,
You have mentioned about rtpengine aswellas rrpproxy in open5g documentation .
The same procedure only I have followed for rtpproxy. And one more thing , I have tried installing rtpengine but libraries are based on Ubuntu bionic . But I am using ubuntu xenial. So libraries are not getting installed properly .
Did everything worked fine for you when you tried with rtpproxy for this version (5.3.3)?

You could simply compile rtpproxy
What I mean about the SDP is the connection parameter, something along the lines of:
c=IN IP4 X.X.X.X
Where X.X.X.X is the up where the receiver must send its rtp. It must be reachable from the receiver.

Hi supreeth,
You have mentioned about rtpengine aswellas rrpproxy in open5g documentation .
The same procedure only I have followed for rtpproxy. And one more thing , I have tried installing rtpengine but libraries are based on Ubuntu bionic . But I am using ubuntu xenial. So libraries are not getting installed properly .
Did everything worked fine for you when you tried with rtpproxy for this version (5.3.3)?

So i assume you are using the examples provided in the ims folder of kamailio repo right? Isn't it using RTPEngine and not RTPProxy? Or have you modified the P-CSCF configuration to work with RTPProxy?

Hi ,
Could anyone kindly tell me if there is any docker image available for kamailio IMS.
I can able to see only kamailio docker images configured as SIP server.

So i assume you are using the examples provided in the ims folder of kamailio repo right? Isn't it using RTPEngine and not RTPProxy? Or have you modified the P-CSCF configuration to work with RTPProxy?

Please check your IMPU for the IMS user in the IMS HSS (e.g. FHoSS or any other HSS you are using to enter IMS user details). SCSCF is not able to find a registered user with that IMPU (i am assuming that you are getting this response while calling)
Increase the debug level on S-CSCF and check out which IMPU is being referred by SCSCF

Hello Pavithra,
I have written a guide for how to integrate an IMS using Kamailio with open5gs EPC, here is the link https://open5gs.org/open5gs/docs/tutorial/02-VoLTE-setup/. You can find steps to setup rtpengine in that guide.
Regarding requirement of rtpengine, its mandatory if you want to use the scripts in that example folder without modification. Also, read the READE of sipwise/rtpengine github repo, its very informative (in a gist rtpengine offer much more feature than rtpproxy)
why can't we have sip client to sip client rtps flowing like how it is
happening without NAT.
For this, i would definitely suggest to read about SIP working. This is a perfect link https://github.com/onmyway133/blog/issues/284 which offers extensive material (short and very interesting to read with examples) related to SIP.

Hi Supreeth,
I have registered the user bob .. and it is already stored in hss database also . Registration is successful with that user .
When i make a call from alice to bob .. in call establishment , it is throwing this error.
In scscf logs , I am able to see registered user not found. But in hss , it is there .
In kamailio.cfg file in scscf, as i already mentioned, it is checking for the condition ,
if(lookup(location))
I am not sure what it tries to do..
Kindly help .

Please check your IMPU for the IMS user in the IMS HSS (e.g. FHoSS or any other HSS you are using to enter IMS user details). SCSCF is not able to find a registered user with that IMPU (i am assuming that you are getting this response while calling)
Increase the debug level on S-CSCF and check out which IMPU is being referred by SCSCF

Hello Pavithra,
I have written a guide for how to integrate an IMS using Kamailio with open5gs EPC, here is the link https://open5gs.org/open5gs/docs/tutorial/02-VoLTE-setup/. You can find steps to setup rtpengine in that guide.
Regarding requirement of rtpengine, its mandatory if you want to use the scripts in that example folder without modification. Also, read the READE of sipwise/rtpengine github repo, its very informative (in a gist rtpengine offer much more feature than rtpproxy)
why can't we have sip client to sip client rtps flowing like how it is
happening without NAT.
For this, i would definitely suggest to read about SIP working. This is a perfect link https://github.com/onmyway133/blog/issues/284 which offers extensive material (short and very interesting to read with examples) related to SIP.

HI,
Hold on a moment,
10.40.10.3 - pcscf in port 4060 (pcscf with NAT enabled in pcscf.cfg (!#define WITH_NAT) and configured rtpproxy) 10.40.10.12 - icscf in port 4070 10.40.10.5 - scscf in port 4080 10.40.10.30 - hss
So i assume you are using the examples provided in the ims folder of kamailio repo right? Isn't it using RTPEngine and not RTPProxy? Or have you modified the P-CSCF configuration to work with RTPProxy?

There is no other IPSec configuration needed apart from running Kamailio P-CSCF and UE sending a SIP Register with Security-Client information for IPSec creation. Kamailio IMS IPSec module creates IPSec tunnels using Netlink library.

Surely this question is better asked on a Freeswan / Strongswan (or whatever name your operating system uses for its IPsec implementation) list - you'll get far more expertise there.

Hi, This is the working pcap files inside openstack environment. kindly check..

when i am making a call from zoiper1 to zoiper2, call is going properly . SIP messages are coming properly in wireshark packets. when i filter for RTP packets in wireshark, it is not coming.

Can you explain some more when you mean by "RTP alone is not coming."? And, how are you checking/verifying that?

Hi ,
Yes I have configured as you mentioned only . In my pcscf only i have rtpproxy also configured. Floating IP i have given in listen address also as listen = 10.40.10.3:4060 advertise 10.45.4.22:4060
10.40.10.3 - private ip 10.45.4.22 - floating ip Still RTP alone is not coming.
Is it the only way of configuring NAT ?
Thanks.

Hello Pavithra,
Have you tried advertising the floating IP of the VM running RTPProxy as follows?
Edit /etc/default/rtpproxy file as follows:
# Additional options that are passed to the daemon. EXTRA_OPTS="-l 172.24.15.30 -d DBUG:LOG_LOCAL0"
here, "-l <PUBLIC_IP>"
Hope it helps.

Hi ,
Could anybody please give me the approach how to configure NAT in kamailio IMS.
I have installed kamailio IMS in openstack environment which has private ips for all four vms (each component in one vm). pcscf has one floating IP attached. I have enabled "WITH_NAT" and configured rtpproxy .
when i make a call from outside of openstack using 2 zoiper clients with outbound proxy keeping floating ip of pcscf, I am getting 200 ok with all SIP packets correctly flowing but there is no RTP Packet.
When i try the same within openstack environment without using public ip, I am getting RTP Packets.
Kindly tell me the procedure of NAT Enablement or do i need to do anything other than this.
Kindly help because i am stuck with this for long time.
Thanks. _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
