今天做ipv6的测试时发现telnet 端口提示权限拒绝，查询相关文档才知道linux 还有一个ip6tables，关闭该服务后telnet正常。关闭selinux 默认是不会关闭ip6tables。

[root@sit2web ~]# service ip6tables stop
ip6tables: Setting chains to policy ACCEPT: filter         [  OK  ]
ip6tables: Flushing firewall rules:                        [  OK  ]
ip6tables: Unloading modules:                              [  OK  ]
[root@sit2web ~]# ip6tables -L
