无法启动iptables服务

我收到这个奇怪的错误：

服务iptables启动iptables：应用防火墙规则：iptables-restore v1.4.7：无法加载匹配“TCP”：/ lib64 / xtables-1.4.7 / libipt_TCP.so：无法打开共享目标文件：没有这样的文件或目录

错误发生在行：18尝试`iptables-restore -h'或'iptables-restore –help'以获取更多信息。 [FAILED]

我已经从FTP更改了规则文件。

• iptables INPUT防止传出邮件和ping
• 在Ubuntu服务器上的ipv6 – 我该如何保护？
• 在shell脚本中的iptables块之间添加睡眠/延迟
• 将iptables链从基于端口改为基于ip
• IPTables和SNAT只有两个端口

规则文件如下：
