環(huán)境：ubuntu 10.10

目標(biāo)：配置網(wǎng)卡啟動(dòng)時(shí)加載iptables規(guī)則

網(wǎng)絡(luò)上搜到的各種操作：

sh -c iptables-save > /etc/iptables.rules

vi /etc/network/interfaces

## 目標(biāo)網(wǎng)卡下增加一條命令

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

但是，經(jīng)測(cè)試發(fā)現(xiàn)。重啟后這些配置會(huì)丟失，查看這個(gè)文件頭會(huì)發(fā)現(xiàn)。

# This configuration file is auto-generated.

# WARNING: Do not edit this file, your changes will be lost.

# Please create/edit /etc/network/interfaces.head and /etc/network/interfaces.tail instead,

# their contents will be inserted at the beginning and at the end

# of this file, respectively.

#

# NOTE: it is NOT guaranteed that the contents of /etc/network/interfaces.tail

# will be at the very end of this file.

文件寫(xiě)得很明確，/etc/network/interfaces是自動(dòng)生成的。如果我們需要自定義配置，那就創(chuàng)建/etc/network/interfaces.head或/etc/network/interfaces.tail。其中/etc/network/interfaces.tail并不推薦。

以下是一個(gè)示例：

auto venet0:0

iface venet0:0 inet static

address 184.22.224.125

netmask 255.255.255.0

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