<br>
Can you try :<br>
<br>
<span><b>echo 1 > /proc/sys/net/</b></span><i><b><span>ipv4</span></b></i><span><b>/ip_forward</b></span>
on the nova-network node.<br>
<br>
And also modify <b>/etc/sysctl.conf</b> to uncomment the ip_forward parameter :<br>
<br>
<b>net.ipv4.ip_forward = 1</b><br>
<br>
<br>
Is it ok now ?<br>
<br>
<br>
Regards<br>
