Hi,
Maybe the MESSAGE is sent to an IP:port:proto destination not used as
listener by OpenSIPS. The tcpdump tool shows the network traffic , but
with no guarantee for the delivery at application level.
So check the listeners in OpenSIPS and the local iptables.

Hi Bogdan,
I encountered another problem.
client send register to opensips then opensips send to server 1.
server1 send 200OK back to opensips and then client
server2 send MESSAGE to opensips. With tcpdump I can see the opensips
server has received the MESSAGE. But opensips process failed to
received it.
I add log in net_udp.c handle_io() , I got log for register and 200
ok. But there is no log for the MESSAGE.
any idea for such error?
Thanks.

HI Sean,
If I understand correctly your setup, you should use into PATH
support on opensips (RFC 3327). Also take a look at the path
module in OpenSIPS:

Hi,
I am new on opensips. could you please help to solve my
questions. Thanks a lot.
My environment:
client is behind NAT(any kinds of NAT),
opensips server has public ip, register server is different
with invite server.
sip server only has private ip but opensips can reach it
directly.
media server has public ip.
So I want opensips solve NAT problem.
1 if I use nathelper module, after contact fix, the server can
only get opensips's private ip and port
2 if I use nat_traversal module, after contact fix, the sip
server can only get the ip watched from opensips.
I want to let sip server get the ip watched from sip server, so
sip server only needs to store one ip. is there such way for
opensips ?
Thanks a lot.
