Hi Kevin, I dont 100% understand what you want to achieve here?<br>
<br>
I assume you want something like this<br>
<br>
Private UAC ----> Opensips Eth1 (private) Opensips Eth0
(public) ------> Public UAC<br>
<br>
If you just want to route between the 2 networks you could look at
enabling multi homed setting<br>
homed=1<br>
<br>
or just use something like the following which I assume is less time
consuming for opensips.<br>
<br>
if ( is_method("INVITE") && src_ip==LOCAL_IP ) {<br>
force_send_socket(PUBLIC_IP);<br>
......<br>
}<br>
<br>
you also need to make sure opensips is listening on the the other
interface for traffic by adding another listen line in your global
config<br>
<br>
listen=udp:NEW_IP:5060<br>
<br>
Regards<br>
Trevor Steyn<br>

<div>HI,</div>
<div>I have a opensips servers in a private network, IP
address: 10.34.14.24, now I'm going to this private
network address 1: 1 NAT to public networks, and modify
the opensips.cfg profile. Register now through the public
network clients can conduct video and audio
communications, and work very well.</div>
<div><br>
</div>
<div>Now I need to add a network card (IP: 192.168.100.100)
on opensips server, and directly connected to a sip client
(IP: 192.168.100.200) through this card.</div>
<div><br>
</div>
<div>How should I modify opensips.cfg, make public sip
client the private network sip client to communicate it?</div>
<div><br>
</div>
<div>Attach opensips.cfg I now use:</div>
