[OpenSIPS-Users] Fwd: opensips server dual network card configuration

Hi Kevin, I dont 100% understand what you want to achieve here?

I assume you want something like this

Private UAC   ----> Opensips Eth1 (private)    Opensips Eth0 (public)
------> Public UAC

If you just want to route between the 2 networks you could look at
enabling multi homed setting
homed=1

or just use something like the following which I assume is less time
consuming for opensips.

 if ( is_method("INVITE") && src_ip==LOCAL_IP ) {
    force_send_socket(PUBLIC_IP);
    ......
 }

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

listen=udp:NEW_IP:5060

Regards
Trevor Steyn
