@ping不通连入无线扩展的TR3000的LAN口的电脑, 你好
你可以尝试用无线中继模式,中继模式完成之后,无线接口会获取一个IP地址(假设为192.168.1.200,当然你也可以设置静态IP自己指定IP地址)作为路由器的WAN口。LAN网段假设还是保持默认的192.168.10.1 255.255.255.0。连接完毕之后,你可以先关闭路由器的防火墙。然后到主的路由器里面增加一条局域网的静态路由条目。目的 192.168.10.0 255.255.255.0,出口LAN, 下一跳: 192.168.1.200 或者你指定的IP地址。
然后你再试试两个局域网互访是不是正常了。注意WAN ping LAN 的时候,被PING的主机的防火墙需要关闭。或者放行外网发送的ICMP 报文,不然被系统防火墙拦截也是ping不通的。
“用TR3000无线扩展连入无线网络后,将电脑A通过网线插入TR3000的LAN口,电脑A能够获取IP,也能访问网络,也能ping通局域网内其他电脑,但是局域网内的其他电脑ping不通电脑A。”
