asa指令改了

今天在測試ASA 5505的時候，看書上與網路上的一些範例，
奇怪怎麼沒辦法下Static與global的指令，查了一下才知道，
原來新的版本改了，現在機器是8.4(3)的版本，
不支援static、global、alias、nat-control等指令，
所以註解一下，免得忘記!!


Note:
1. Old NAT commands - static, global, alias, nat-control have been deprecated
   and the functionality may be achieved by using the new 'nat' command.
   Please refer to documentation for more details.
2. The interface fallback is supported only for dynamic NAT.
3. The unidirectional option is supported only for static NAT.
4. Service objects having protocols other than TCP or UDP are not supported.
5. pat-pool related parameters are supported only for dynamic NAT.
