The reason should be fairly obvious, to use an address as a gateway on an
interface (tunl0) you must have a route to the gateway first wheater that
is a network route or a specific host.

My question is how do you set it up without the trick? Between the time
you add the host and remove it, you essentially have a backhole or a loop
or something for that host. While it might be the hack way I don't see it
as the right way.
