Using Openser as Proxy and Asterisk as Registrar

Cosimo Fadda
Hi everybody,
I'd like to implement this scenario:

-----------              -------------------              ---------------
|  GW/FW  
|<----LAN1---->|eth0|Openser|eth1|<----LAN2---->|eth0|asterisk| -->PSTN
-----------              -------------------       |      ---------------
        |_______________________________________________|            
                                                                         
                         
Where:
- Openser is reachable from the outside  with a public  IP forwarded to
eth0 private address;

- Asterisk is connected to Openser using another separated LAN
- Openser acts as proxy (for requests coming from the  outside) and
Asterisk act as registrar and gateway.


This is the description, now the questions:
-since opneser has two different nics, how can configure it to properly
send register request to asterisk?
This is what currently happens:
192.168.40.68:5060: is eth0 Openser Address
192.168.12.165 is eth1 Openser Address
192.168.12.106  is Asterisk address
82.187.X.X is Openser public address
Network 192.168.40.X is not reachable from net 192.168.12.X

So asterisk sends response to the wrong interface.

How can I solve this?

Thanks in advance,

C.

Hello Cosimo,

you can control what interface to be used for sending out requests via
the force_send_socket() command:

Bogdan
