超级变态问题...

以下为两台路由器的配置

华为 2621

以上两套配置.都是放在网吧当网关的。结果NAT做了以后。都是发现内网无法访问

比如输入61.153.252.42 无法访问网页。而在外网。输入61.153.252.42 一切正常

思科路由器。在运行后还发现无法进入泡泡糖游戏...输入帐号密码后。提示udp协议运行不正常

开始游戏。发现卡住。然后提示网络不稳定。断开连接

换成华为2621 就无此问题。也没有提示

但是他们共同的毛病就是。做了NAT到内网 192.168.0.233 的80 7000 7100 7200

都是外网游戏和访问一切正常。网吧内部。无法访问网页。进入游戏不开门.晕了
