请教论坛上的告诉，我的DD-WRT是不是一直在被攻击

lingx***

从系统日志里截取的，一直有几个IP论坛远程登录,有没有办法限制远程可以访问的IP地址，最好是MAC地址，拒绝这些访问攻击？一直被攻击，路由器总是重启，很烦躁啊。
类似这样的记录：

看不懂请大神指点吧

在路由器的 服务 里,
SSHd
  禁用
Telnet
  禁用

然后在 管理
远程管理

Web界面管理
禁用
SSH管理
禁用
Telnet管理
禁 用
允许任意远程IP地址
启用
允许远程IP地址范围(然后输入你电脑的IP段)
如192.168.1.2终止于10意思就是 只有IP是192.168.1.2到10的才能进管理网页

SSHd和Telnet不用的话就禁用,如果要开启,请改端口(将22/23改掉)如23512之类的

还有路由器的登陆密码不要过于简单
