The communication is from the agent to controller only from my
understanding. This is what allows a user to provision juju deployed
infrastructure behind any nat gateway, and for lxd deploys to work on
providers without juju networking support for containers (where the
containers get the lxdbr0 nat). Here is a good example of both scenarios in
one model http://paste.ubuntu.com/24749128/
