# sudo vi /etc/network/interfaces 增加虛擬網卡設定
auto eth0
iface eth0 inet static
address 192.168.1.253
netmask 255.255.255.0
gateway 192.168.1.254

====以下為虛擬網卡設定====
auto eth0:0
iface eth0:0 inet static
address 192.168.2.253
netmask 255.255.255.0
network 192.168.2.0
broadcast 192.168.2.255
====以上為虛擬網卡設定====

# sudo /etc/init.d/networking restart 重新啟動網路服務
