vlan
ghs3使用c3700模擬switch使用vlan時要連結到fastethernet1/x才可以，fastethernet0/x是屬於router部分指令會出錯

static ip
router基本上無法設定gateway，一般router可以設定default gateway是因為已經與switch合併，故當需要設定時可以當作switch使用

dhcp
在分配IP時要將router介面設定ip並在dhcp default-router設定此ip

切換介面
Router1(config-if)#ip nat inside
切換介面
Router1(config-if)#ip nat outside
Router1(config)#access-list 1 permit any any
