<p class="MsoNormal">To me it seems, that you have a private address for your container, 10.x.x.x, and you connect the network over a bridge interface.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">if you are using bridging, you need a separate public-IP for your container(s).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">If you want to connect to the internet over a single public IP (the IP of your eth0 I assume) you will need to set up IP-mascarading or NAT, or a reverse proxy, to translate communication between your virtual LAN, and the internet.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Depending on your needs, you might have also the option to use IPv6, the above is for classic IPv4.<o:p></o:p></p>
