使用object-group 能大大簡化配置工作量，很實用。
防火牆上的配置：
object-group service gjlyd tcp
description used for hai nai guo ji lv you dao server
port-object eq 445
port-object eq ftp
port-object eq 3389
port-object eq www
port-object eq 8080
port-object eq 1433
object-group network gjlydser
network-object host 10.9.2.66
network-object host 10.9.2.67
network-object host 10.9.2.68
access-list inside permit tcp host 10.2.57.67 object-group gjlydser object-group gjlyd
access-list inside permit tcp host 10.2.57.151 object-group gjlydser object-group gjlyd
輸出：（看着很爽）
