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
