Additionally to what nowy1981 has pointed out about breaking rule number one
(Virtual Template is not physical), it is usually stated in global lab rules
that you should use "simplest method possible" or "most straightforward
manner" or somewhere along those lines.
PPPoFR is not the simplest, sine there is a considerably simpler one.
