Hi,
I use the ser.cfg below. I have rtpproxy running. Sipura 2000 can register now without STUN server. However, the registration port is 58698 not 5060.
Here is the SIP address after registration: sip:811@218.xxx.xxx.xxx:58698

Hello Thomas. I think you're missing a few important things. First i don't see any checks for NAT'd endpoints, you need to do something like this:
if (nat_uac_test(1)) setflag(1); force_rport(); fix_nated_contact();
then in the INVITE:
if (method=="INVITE") { record_route(); if (isflagset(1)) fix_nated_sdp("3"); }; /* set up reply processing */ t_on_reply("1"); };I'm using mediaproxy, so i am not sure about this, maybe somone that's using the nathelper module can help you better... you can check the example configuration file in the /modules/nathelper directory, that could give you some clues.
Cheers.

-----Mensaje original----- De: support [mailto:support@cybertel.biz] Enviado el: Miércoles, 15 de Diciembre de 2004 4:38 Para: serusers@lists.iptel.org Asunto: [Serusers] rtpproxy + nathelper problem
Hi,
I have installed the latest rtpproxy and run it with ser-0.8-14. I have also include nathelper modules. When I try to register a siprua gateway with SER, the IP is still 192.168.1.xx. It cannot be translated to NAT public IP.
Why is that so?
Thanks.
Thomas
