С cisco первый раз, помогите пожалуйста:

Имею такую схему:

интернет (dsl modem)внешний IP XXX.XXX.XXX.246 >> Cisco ASA 5505 (192.168.1.1) >> к ней подключен DC (win server 2008) 192.168.1.2 и свич, к свичу локальные машинки и сетевое оборудование

dhcp на dc выключен

Задача:
1. сделать возможным хождение любого трафика по внутренне сети
2. раздать интернет в простейшем виде
3. сделать порт форвардинг из инета на одно сетевое строуйство внутри (192.168.1.140)

вот что смог навоять:

Result of the command: "show running-config"
