在Cisco 1841上允许端口8080
在Cisco 1841上允许端口8080
提问于 2016-11-16 20:44:35
在配置1841以允许外部访问将某些端口映射到内部地址时遇到问题。
需要允许以下方面：
外部IP:端口8080至192.168.3.50外部IP:端口8081至192.168.3.51
下面是1841的配置：

下面是一个常规的静态PAT语句。
ip nat inside source static tcp 192.168.3.50 8080 98.190.71.2 8080 extendable
ip nat inside source static tcp 192.168.3.51 8081 98.190.71.2 8081 extendable这可能是UDP流量所需要的。
ip nat inside source static udp 192.168.3.50 8080 98.190.71.2 8080 extendable
ip nat inside source static udp 192.168.3.51 8081 98.190.71.2 8081 extendableNetwork Engineering用户

您的要求似乎是入站通信量，希望从外部网络访问内部网络中承载的服务器。要建立此连接，静态存储必须在边缘设备或外围设备中进行配置。
静态NAT
路由器(配置)# ip nat在源静态192.168 .3.50 X.X eq 8080中
路由器(配置)#ip nat内部静态192.168 3.51 X.X eq 8081
其中X.X是外部的(公共IP地址)
