linux – Iptables忽略配置文件中的规则

我从ip 188.241.114.22看到很多与我的apache服务器建立的连接,最终导致apache挂起.重新启动服务后,一切正常.
我尝试在iptables中添加规则

-A INPUT -s 188.241.114.22 -j DROP

但尽管如此,我仍然看到来自该IP的连接.
我正在使用centOS,我正在添加像你这样的规则：

iptables -A INPUT -s 188.241.114.22 -j DROP

正好我用它来保存它：service iptables save
这是iptables -L -v的输出


    Chain INPUT (policy ACCEPT 120K packets,16M bytes)

     pkts bytes target     prot opt in     out     source               destination

    0     0 DROP       all  --  any    any     v1.oxygen.ro         anywhere

Chain FORWARD (policy ACCEPT 0 packets,0 bytes)
 pkts bytes target     prot opt in     out     source               destination

Chain OUTPUT (policy ACCEPT 186K packets,224M bytes)
 pkts bytes target     prot opt in     out     source               destination

解决方法

命令iptables -A INPUT在INPUT链的末尾添加一个新规则. Iptables在第一个匹配原则上工作,因此您可能有规则允许在链中较早的端口80上访问.

使用a保存iptables的状态

服务iptables保存
然后编辑/ etc / sysconfig / iptables文件并将-A INPUT -s 188.241.114.22 -j DROP移动到允许端口80的行上方.保存文件并运行

service iptables restart
