[Asterisk-Users] Dual NAT for SIP

[Serge Schumacher]

Hi,

My installation at home use two NAT translations before it reaches the linux box where Asterisk is running on.

I use DSL with a Wireless router which fwd all packets to an Windows 2003 box an this windows box it NATing the UDP and RTC packets to my linux box.

If I try to connect to it from outside I get this error :

Nov 30 22:19:02 WARNING[1106250672]: chan_sip.c:673 retrans_pkt: Maximum retries exceeded on call 4f106a72453f654a for seqno 1 (Non-critical Response)

Well the users can connect but unable to establish a voice call between two SIP clients.

Someone a clue how it can be solved or... ?
