#241: Bind to wrong IP / interface
----------------------------+-----------------------------------------------
Reporter: bcx | Owner: vadim
Type: defect | Status: new
Priority: major | Milestone: QuteCom 2.2-RC4
Component: 3rd party libs | Version: 2.2
Keywords: | Field_os: linux64
----------------------------+-----------------------------------------------
On initiating a connection to my asterisk server, QuteCom uses a false IP
address to bind to.
I'm using the 2.2~rc3 ubuntu version.
I used wiresharke to monitor the traffic, the only packet that qutecom
sends is this "SIP REGISTER" packet:
---------------------------------------------
REGISTER sip:172.24.1.8 SIP/2.0
Via: SIP/2.0/UDP 192.168.1.16:5060;rport;branch=1372600058
Route: <sip:172.24.1.8;lr>
From: nobody <sip:[email protected]>;tag=450342120
To: <sip:[email protected]>
Call-ID: 478487930
Contact: <sip:[email protected]>
CSeq: 2058777079 REGISTER
X-Wengo-Ping: network test
Content-Length: 0
---------------------------------------------
This packets source IP is 192.168.1.16, destination IP is 172.24.1.8
192.168.1.x is on my eth0 interface, my local lan (home network).
172.24.x.x is on my ppp0 interface, a VPN connection to my work network.
My VPN connection is functioning fine, for both tcp and udp traffic.
I think the source IP should be: 172.24.4.15.
