<br>
The whole IP configuration for the container looks like this:<br>
IP address: 91.143.88.119<span class=""><br>
netmask: 255.255.255.0<br>
broadcast: 91.143.88.255<br>
gateway: 91.143.88.1<br>
<br></span>
So the container is on a totally different subnet, but shouldn't that work anyway with a bridged device?<br>
<br>

In your container config you set the IP gateway as:<br>
<br>
lxc.network.ipv4.gateway=91.<u></u>143.88.1<br>
<br>
But I didn't see that IP addr anywhere else in your email. Where is 88.1 ?<br>
