Hi,
Looks like you are mixing together nathelper and mediaproxy module.
You need to call force_rport() even for INVITEs.
Look at Getting started ser configs

Hi,
This is under my method=="REGISTER" section:
if (nat_uac_test("1")) {
setflag(6);
fix_nated_contact();
force_rport();
};
I also have this under method=="INVITE" :
if (method=="INVITE" || method=="ACK") {
if (client_nat_test("19")) {
fix_nated_contact();
};
And this one under a onreply route :
onreply_route[2] {
if (status=~"(183)|(2[0-9][0-9])") {
use_media_proxy();
if (nat_uac_test("19")) {
fix_nated_contact();
};
}
};
Thanks for your reply...

Hi,
do you call force_rport() function for NATed clients?
Can you paste in the NAT section of your ser.cfg here?
Paste in NAT detecting section too.

Hi,
I have a working configuration on my SER server. Most of the users can make calls (both
way incoming and outgoing) with no problem.
However, I have some clients that can't make calls.
When I analyze these by ngrep and/or tcpdump, I see that the SER server does not reply
the packet on the correct port.
For example, I have a testing client which is behind NAT.
The client sends INVITE message from UDP port 3023 to port 5061 of my SER.
(cseq number is 1)
SER exchanges the message with the uplink sip gateway and when it
receives a "OK" response it forwards this message to the client's NAT
IP address BUT on a different port (14640) with correct cseq number
(1)
Of course, this new port is not open on the NAT router and it does not reach the client.
I see that the first INVITE message has Contact field with internal IP address of the
client and the port number as 14640.
So the SER server sends the returning message to the external IP address with internal
port number.
How can I fix this issue ?
I can send the configuration of my SER server if that would help to find the problem.

New subject: [Serusers] interesting 2 way SIP signalling problem
Hi,
I tried adding force_rport() for INVITEs.
But that didn't solve the problem.
Then I checked the "getting started ser configs" from the ftp URL you sent.
This one should be fine:
ftp://siprouter.onsip.org/pub/gettingstarted/configs/nat-mediaproxy.cfg
However, this config includes the following line:
modparam("registrar", "nat_flag", 6)
But my new compiled ser installation (and its registrar module) does not accept this
parameter.
Which source/build would have this parameter ?
If this parameter is not important I can ignore it...
Please show me a way.
Thanks,
ilker

Hi,
Ok, I know now that you are using version SER 2.1 :). (the CVS version)
I have changed the ser config file which can be used with mediaproxy.
Please try it out since I don't use mediaproxy.. The change is not that
much different from using RTP proxy.
You can find it here
http://www.iptel.org/ser/howtos/optimizing_the_use_of_rtp_proxy
File is called <ser_config_2_0_mediaproxy.txt>
Or directly from http://www.iptel.org/files/ser_config_2_0_mediaproxy.txt
I will move it later to its section if it will be working for you.
Regarding nat_flag in SER 2.0 and 2.1. There are used 2 nat flags .
save_nat_flag and load_nat_flag.
This way it is in modparam section.
modparam("registrar", "save_nat_flag", "FLAG_NAT_UAC")
modparam("registrar", "load_nat_flag", "FLAG_NAT_UAS")
As an example look at the config file mentioned above.
Let me know if it is working.. I'll help you to start up SER with this
config if you find any problems.
It should work though.
