配置网卡
假设：你的网卡是 eth0 ，通过 ppp0 上 Internet.

sudo gedit /etc/shorewall/interfaces

在倒数第二行，也就是在 “#LAST LINE -- ADD YOUR ENTRIES BEFORE THIS ONE -- DO NOT REMOVE” 这一行之前添加：

net ppp0 detect dhcp,routefilter,norfc1918,tcpflags
loc eth0 detect tcpflags

昨天安装了ubuntu6.06,今天安装shorewall出错。忘高手指点！
1）用apt-get install安装。
按FireHare教程：http://wiki.ubuntu.org.cn/ShoreWall%E5%AE%89%E8%A3%85%E8%AE%BE%E7%BD%AE


在复制配置文件时出错。

后面几个rules.gz host.gz masql.gz也出现同样错误。
查看，原来在/usr/share/doc/shorewall/default-config/下面根本就没有这几个文件。（我用5.05时是有的）
但是其目录里有 interfaces rules host masql这四个已经解压了的文件。
于是，我直接将他们copy过去。

在配置时又出现以前5.05时的错误：

我把shorewall文件目录及interfaces文件都设置成777，还是出错。
