just that we're on the same page. Please have a look at this picture:<br>

<br>
With the provider network you create a network that matches the green<br>
External & the purple api network (as you have a combined controller +<br>
network node). This is where you already have vlan, right?<br>
<br>
And on the green data network you try to use gre, right?<br>
<br>
Or does you controller only have one physical nic for all kind of<br>
traffic?<br>
<br>
<br>
I'm sorry but I do not yet understand your setup and what you're trying<br>
to achieve.<br>
<br>
Please keep always the mailing lists on cc, as others might also be<br>
interested.<br>
<br>
<br>
<br>
Regards,<br>
Andreas<br>
