<p>i am investigating about it but i didn't found anythin related with it.</p>

<p>With the information that you provided, check yout host configuration, because it looks that it needs permission, and run this:</p>

<pre><code>echo "1" &gt;/proc/sys/net/bridge/bridge-nf-call-iptables
</code></pre>

<p>This modified you OS to enable bridge calls</p>
