Oh, ok I misunderstood.

Yes, you can, with the installed 'ip-utils' tools (guessing you have a 
recent version).

1 - find the pid of one of the process running in the container
    lxc-ps --lxc will help in this case

2 - assuming you have a pid 1234, use the following syntax.

    ip link set ppp0 netns 1234

At this point the 'ppp0' interface should be in the container, but you 
won't be able to move it back to the host.

I noticed the kernel has flagged 'ppp_generic' with the 
NETIF_F_NETNS_LOCAL, so it should not be movable across namespaces, but 
let's see if that works for you ...

Thanks
