Ubuntu安装使用iptables

sudo apt-get install iptables-persistent

iptables-save > /etc/iptables.up.rules 

接着修改 /etc/network/interfaces 脚本自动应用这些规则(末行是添加的) 

auto eth0 

iface eth0 inet dhcp 

pre-up iptables-restore < /etc/iptables.up.rules 

你也可以准备一组规则并自动应用它 

auto eth0 

iface eth0 inet dhcp 

pre-up iptables-restore < /etc/iptables.up.rules 

post-down iptables-restore < /etc/iptables.down.rules
