I need a bridge interface for LXC networking to work. Normally I just do something like this in /etc/network/interfaces:
auto br0 iface br0 inet dhcp bridge_ports eth0
But Raspbian uses
How do I create a bridge on an RPi?
I'm not sure how the internals of LXC work, but I know for a fact that LXC needs a bridge in order to work. I have tried LXC's NAT and couldn't get that to work, and I don't want a NAT layer anyway.
