iptables 由表(table)、链(chain)和规则(rule)组成,其中表包含链,链包含规则 表 filter:这里面的链条,规则,可以决定一个数据包是否可以到达目标进程端口 三个链:INPUT、FORWARD、OUTPUT 内核模块:iptables_filter mangle: 这里面的链条,规则,可以修改数据包的内容,比如ttl ...
iptables 使用 table 来组织 rule,根据 rule 是被用来做什么业务类型处理,将 rule 分为不同 table。例如,如果 rule 是处理网络地址转换的,那会放到 nat table;如果是判断是否允许数据包继续转发,那可能会放到 filter table。 在每个 table 内部,规则被进一步组织成 chain,内置的 chain 是 netfilter hook 触发的,...
