[Asterisk-Users] * and NAT

[John Khina]

Hi All ,

I'm having issues with * and getting connections  outside of my  local 
lan . My * server is sitting behind a firewall which performs NAT . I 
have setup the port forward , configured externip= xxx.xxx.xxx.xxx and 
also have configured the client phones with nat=yes , careinvite=no , 
and qualify=yes .

The error Im getting after  it attempts a native bridge between my * 
server and a client over the internet is:
"Warning[3197]: chan_sip.c:678 retrans_pkt: Maximum retries exceeded on 
call 1070E9D8-3AC8-11D9-8EB2-000A9568C782 at 192.168.144.50 for seqno 
1469"

The error is giving me the client's internal IP address , though it is 
sitting behind another Nat'd internet connection.

Connections on my Lan are working , Has anyone got any suggestions?

Thanks in advance

JK
