I am trying to build a build a fail-over router (adsl / wwan
card).<br>
I am using openvswitch as my virtual switch and kvm to build some
VM.<br>
I already connected my wwan nic(</font><font size="-1"><font
size="-1">pnic_wwan, wwan0 renamed)</font> on the openvswitch
bridge (</font><font size="-1"><font size="-1">vswitch_wwan)</font>
and everything is working fine.<br>
I can get an IP address and navigate on Internet, no issue!<br>
<br>
Now the thing get more complex when I want to retrieve the IP
address on a virtual nic (</font><font size="-1"><font size="-1">vnic_v00_w_secu)</font>
connected into the same virtual switch (</font><font size="-1"><font
size="-1">vswitch_wwan).<br>
In fact,</font> I would like to have a VM where I start an
openvpn instance to be able to monitor the traffic thanks to some
SPAN capabilities on openvswitch.<br>
<br>
In my VM I am able to retrieve the IP address from the wwan
interface but impossible to navigate on Internet.<br>
I made some packet capture analysis and I am suspecting that my
virtual machine tries to talk to a 'virtual-fake' mac address from
the wwan interface (02:50:f3:00:00:00) but it is is impossible to
reach it.<br>
<br>
Is it a normal behavior? Am I able to do a type of arp proxy on my
host to be able to reach the mac from my vm? Or if there is any
workaround for that..<br>
Many thanks for any idea as I know it is quite a uncommon question
:)<br>
