That's what I'm trying to achieve. I'm not using pppd and my problem is
as follow: I need to isolate ppp devices from each other, even when
they are connected to sessions carried by the same L2TP tunnel. Also, I
need the authentication to be terminated to know the namespace in which
the ppp will be moved. For that, the process runs in a namespace with
its l2tp sockets (tunnel and session) in that same namespace and each
ppp device is moved in a specific namespace after authentication.

François
