Hi David, thank you for you answer,

Hi!
I had the same problem (My PC was responding everything it receives through the default gateway "eth0" ). Everybody say that it was an Asterisk bug, but it was a problem in the routing table.
Yes, I'm new to Openser but I know quite well Asterisk, and I don't think it is a bug or a misconfiguration .
Type route in a terminal and check if they are the way you are thinking. If
not, add the correct route. Tell me if it solve your problem.
The route table is correct, but a strange thing happens since the SIP packet is sent from the correct nic, but un the UDP header of that packet I see as source the IP of the other nic (the one that received the orinal packet)
I have to investigate a little more on this aspect anyway.

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,
