您好，请知：

无法上网，以下是排查要点，请参考：

1、在电脑从网关开始PING，一路PING到路由器的外网出口地址，看下是否能PING通。

2、由于是PPPOE的拨号上网，需要在拨号口配置nat outbound

3、需配置默认路由指向到外网，使用的是拨号口作为出接口。

4、电脑调整下DNS为所接入运营商的DNS。

还是没有能配置上网，我客户端单独可以PING通到dialer1的PPPOE拨号地址 114.228.158.121 ，用命令pathping 221.228.255.1时，在网关这里就显示不通了 192.168.0.1 这里就显示*.*. ，在U200-A中ping客户端192.168.0.2/客户端ping 192.168.0.1都可以ping通，
