NAT转换失败

小弟最近遇到一个NAT问题。在路由器配置一个静态NAT  ip nat inside source static 221.7.61.248 10.241.50.134.    221.7.61.248 作为本地LAN的一台服务器,对方通过FTP来下载服务器内容,在路由器上配置 ip nat inside source static 221.7.61.248 10.241.50.134.  过不了多久对方会与这台本地LAN的服务器断开连接,必须到路由器上删除NAT,然后重新创建,网络才恢复,过不了多久又会断开。

日志上看不出来啥错误,网络中断的时候,对端是软件检测的,还是说你测试了连21端口都不通?

对端到本地LAND这台服务器都不通,有没有什么方法排错,刚才是通过Debug收集的信息。

这个是正解,你内网地址是221.7.61.248 ? 公有10.241.40.134?
你理解反了吧?

路由器的LAN口和WAN口,是否设置了IP  NATINSIDE和 ip  natoutside??
我记得路由器上写好nat转换后,一般都匹配访问控制列表,
能否给个简单的拓扑,光这么说我们没法帮你排除其他的故障点。

如果说路由器的配置确认没有问题,看看你的服务器防火墙的出站和入站规则。还有FTP的服务配置是否正常。
