<br>
You can make changes in /etc/network/interfaces as follows:<br>
1. Define interface br-ex, give it static IP same as em3.<br>
2. Add em3 to promiscuous mode.<o:p></o:p></p>

<p class="MsoNormal">Hi Andreas<br>
Yes you're absolutely correct about this, when I use<br>
ifconfig em3 0<br>
ifconfig br-ex <a href="http://172.22.17.12/24" target="_blank">172.22.17.12/24</a><br>
I can ping the default gateway 172.22.7.1<br>
<br>
But, how would you configure this permanently? i.e. how would you edit the network configuration file:<br>
/etc/network/interfaces<br>
To make this a permanent configuration?<br>
<br>
Thanks a lot for your help !<br>

<br>
Hi Yngyi,<br>
<br>
this absolutely makes sense.<br>
<br>
As soon as you add a port to a bridge (doesn't matter if linux- or<br>
ovs-bridge) it cannot be used as ip interface anymore. What you have to do after you've added this interface to br-ex, you have to "move up" the ip address to the br-ex.<br>
<br>
e.g.<br>
> ifconfig em3 0<br>
> ifconfig br-ex <a href="http://172.22.17.12/24" target="_blank">172.22.17.12/24</a><br>
<br>
And you should be fine<br>
<br>
<br>
Hope this helps!<br>
<br>
