如何永久更新iptables [英] How to permanently update iptables

问题描述

我正在尝试将http流量重定向到同一台计算机上的端口8080，并使下面的iptables规则正常工作.

I'm trying to redirect http traffic to port 8080 on the same machine and have the iptables rules below working.

推荐答案

一种方法是:

One way to do this would be:

vim /etc/network/interfaces

在您的lo指令后面加上以下行:

Append the below line along with your lo directives:

post-up /sbin/iptables-restore < /etc/iptables-up.rules

现在运行以下命令

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

我希望这会有所帮助.
