iptables 显示警告消息，但我无法解决它

当我在 SSH 中输入此命令查看规则时，iptables 中返回以下警告消息。我想知道这是什么以及如何解决它。iptables -L

LOG        tcp  --  anywhere             anywhere             limit: avg 30/min burst 5 LOG level warning                                  prefix "Firewall: *TCP_IN Blocked* "

您说的警告信息是什么？您是指警告字里行间是否有与此类似的词？

LOG  tcp  --  anywhere  anywhere   limit: avg 30/min burst 5 LOG level warning prefix "Firewall: *TCP_IN Blocked* "

这不是 iptables 显示的警告消息，而是描述规则的输出的一部分。因此，level warning显示您--log-level warning在创建LOG规则时已指定。无需担心！
