Wrong source address with TUN/TAP interface

Description
Hello,
On Windows, when using Qutecom with a VPN which creates a TUN/TAP interface (for example OpenVPN), the source address used is not the address of the TUN interface but the address of the physical interface.
For example, the ethernet is 10.0.0.1 and VPN 172.16.0.1, if the traffic is set to go out from the VPN interface, the packet have 10.0.0.1 for source instead of 172.16.0.1 (I have used wireshark on the TUN interface to get this information, so I'm sure the packets exit by this interface with the wrong source address). Because of that, the connection cannot be established.
Qutecom is started after the VPN is established.
Thanks,
Julien

- Milestone set to QuteCom 3.0
Can we know any estimate date, when can we expect resolution for this issue ?
This issue seems to be very major, as other softphones already have this functionality, so qutecom should be on the same stage as well.

QuteCom 3.0 will use Bearer from Qt 4.7 to detect network devices ...
integration is not finished yet ... gui part is missing ( patch are welcomed ;)
You can try to hack network device identifier in config.xml with "network.interface" key.

bug fix 79

I have same problems on Debian: tcpdump on OpenVPN server (bridged configuration) says that packets are sent with wrong source address (IP-address of my Wi-Fi connection on client) and QuteCom can't establish connection.
