我已经运行了iptables,因为我可以使用以下命令…
sudo / sbin / iptables sudo / sbin / iptables -t nat -I PREROUTING -p tcp –dport 80 -j REDIRECT –to-port 8080
但我不能……
服务iptables保存
iptables:无法识别的服务
当我重新启动服务器时映射停止时,如何实际保存这些更改?
谢谢.
据我所知,Ubuntu在最新版本中使用了
UFW,因此很可能它没有iptables的SysV init脚本.如果您对UFW不满意,可以使用sudo iptables-save> /etc/iptables.rules存储你当前的规则,然后调用sudo iptables-restore<来自rc.local的/etc/iptables.rules(例如)恢复启动时的规则. 或者,您可以按照指定的
here为iptables添加自己的init脚本:
