0536 联通，默认给公网 IP ，光猫使用 F7607P 移动固件手动配置数据桥接小米万兆路由器拨号上网

在 0531 电信用 Windows ping 提示：

是路由器的配置问题还是运营商封了 ping ？

运营商那边给了假公网吧

换光猫之前还能正常 ping 通，难道是因为 tr069 掉了运营商看离线就给了假公网吗

[techtony]

个人经验 运营商有可能随时收回公网 IP ，需要找客服要一下，以后就不回收了

插电脑上拨号看看 ping 不 ping 得通电脑 记得 Windows 放开 File and Printer Sharing (Echo Request - ICMPv4-In)

要不重启一下路由器？我用小米路由器内网都经常 ping 不通内网 ip
