<div class="moz-cite-prefix">We had here same problems like you, but
with public IP Addresses only.<br>
Please post your lxc config. Our Workaround was to set a fixed
net.hw address but maybe your problem is different.<br>

<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>
