IPTABLES错误“ iptables：该名称没有链/目标/匹配”

问题描述

iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 8080

当我尝试运行此命令时，遇到了以下错误：

我的iptables版本是v1。 4.14。
在Linux内核3.8.11上运行debain。

我不知道问题出在什么地方，我看着，没有其他人知道

I have no clue what the problem is, and I looked and nobody else has had this error with this setup.

推荐答案

该错误表示您缺少内核中的iptables REDIRECT模块。

The error means that you are missing the iptables REDIRECT module in the kernel.

也许您自己编译了内核？然后您需要启用/设置选项

Perhaps you compiled the kernel yourself? Then you need to enable/set the option

CONFIG_IP_NF_TARGET_REDIRECT=m

在您的内核配置中，然后

in your kernel config and then

make modules
make modules_install
depmod -ae
