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?
if you want to force an interface for outgoing sip requests, see
force_send_sock() function:
http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:1.4.x#force_send_so…
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?
Probably the right answer you will get on the asterisk mailing lists.
Cheers,
Daniel
