Ok, I've just did it now.  I launched my VPN within a container.  Then
on my host I searched for the $PID of the process and then:

nsenter -t $PID -n firefox

Now Firefox shares the network namepsace of the running container
(without having to create a "firefox container" beforehand...).

I did this test as root.

HTH,
Jorge
