A bridge is its own logical entity in the kernel to which you may attach devices. You can not "attach a bridge" to something else. You can only attach something else "to the bridge". There's a difference. In the case of a NATing configuration, you set up a bridge (name it whatever you want) and attach the containers to it. Then you use the NAT modules to route between the bridge and the external interface while NATing the addresses. I use "lxcbr0" on my Fedora hosts. It's just a bridge. I could see where Ubuntu might have some preconfigured setups for this purpose where I have to set them up by hand in Fedora. That's just a matter of the distro specific support scripts.
