</strong>Using dial-on-demand will bring the connection up again if any packet
triggers it. To substantiate this point: disconnecting manually
will <strong>not</strong> prevent dial-on-demand from making connections
to the outside! Don't use dial-on-demand if you want to make sure that the line is kept disconnected.
