選択肢
- The outer box holds one serving zone per client system that reaches it, the inner box holds one asking zone per server it reaches, and the ports and the protocols written on a matched pair of those zones agree.
- The inner box holds one asking zone per server it reaches, and the protocols written on the pair of zones are picked by the outer box and pushed down to the inner one.
- The outer box holds one serving zone per client system that reaches it, and the ports and the protocols written on the pair of zones are picked apart on the two sides so that a clash between them is ruled out beforehand by the technician.
