我需要将端口8080重定向到Linux服务器上的端口80。
我的问题是一样的：
https://askubuntu.com/a/579540
唯一的区别是我没有iptables-使用firewalld可以做到这一点吗？
编辑：现在我知道firewalld使用iptables，并且可以使用以下命令通过firewalld将命令传递给iptables：
firewall-cmd [--permanent] --direct --add-rule { ipv4 | ipv6 | eb } <table> <chain> <priority> <args>
我有：
在端口8080上运行的HTTP服务器
端口80重定向到Firewalld中的8080（区域公共）
来自其他通过端口80访问的计算机的客户端可以访问HTTP服务器
我可以从运行服务器的同一台计算机上的端口8080上访问服务器
我也要：
从运行服务器的同一台计算机访问端口80上的服务器
我试过了：
将接口“ lo”添加到区域“ public”
以与“公共”区域相同的方式配置“受信任”区域
区域“公共”配置：
<zone>
<short>Public</short>
<description>For use in public areas. You do not trust the other computers on networks to not harm your computer. Only selected incoming connections are accepted.</description>
<service name="snmp"/>
<service name="http"/>
<service name="ssh"/>
<service name="https"/>
<icmp-block name="redirect"/>
<icmp-block name="router-solicitation"/>
<icmp-block name="parameter-problem"/>
<icmp-block name="router-advertisement"/>
<forward-port to-port="8080" protocol="tcp" port="80"/>
</zone>

编辑：解决方案：
服务器根本没有监听回送接口。
最佳答案
服务器未在回送接口上侦听。
