Have you an are publish on your linux box?

You need to satisfy layer 2. Your jnos has no mac address and so your dsl
router cannot find it. Bear in mimd that on your LAN things happen at the
mac layer.

In short you tell  your linux box to advertise itself as the holder of the
jnos tun0 address.  Dsl will swnd packets to linux which will then look at
the IP layer and move it on to jnos.
