[Serusers] problem with nathelper and rtpproxy

[Alexander Didebulidze]

Hi,
I have problems setting up nathelper on already long time working SER
server.

my config is here : http://pastebin.ca/1786

I want to proxy all not local calls using rtpproxy to internet (later
ipv4-to-ipv6 too)

I have last cvs of rtpproxy and ser 0.8.14 on debian sarge... 
ser can see rtpproxy and on outgoing calls i see in rtpproxy -f2
output :
rtpproxy: new session E2D420E7-BBAE-47B0-80E8-EFB777ABED78 at 10.150.63.27,
tag 520152133 requested
rtpproxy: new session on a port 35000 created, tag 520152133
rtpproxy: pre-filling caller's address with 10.150.63.27:8000
rtpproxy: session timeout
rtpproxy: RTP stats: 0 in from callee, 0 in from caller, 0 relayed, 0
dropped
rtpproxy: RTCP stats: 0 in from callee, 0 in from caller, 0 relayed, 0
dropped
rtpproxy: session on ports 35000/0 is cleaned up

and in ethereal i see only one packet send to iptel.org (I'm trying to
call iptel :) )  this packet is INVITE , and in headers i can read
contact: user at 10.150.63.27:5060

is it ok... i thought that it have to be something like
asdadasd at sip-proxy.domain:38XXX

what am i doing wrong? have i to start rtpproxy with some parameters ? i
tried with -l <localip> but same result

Thanks in advice,
Alexander
