Also, L2TP's tunnel socket (UDP or > L2TP/IP) will be in a different namespace if the ppp interface is moved. 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.
