思科2811路由器端口映射如何设置

你需要把外网10.0.0.1的3389端口映射到内网192.168.1.2的3389端口。这样来进行操作 ip nat inside source static tcp 221.131.44.150 80 192.168.0.88 80。

其次是Router(config)#ip nat inside source static tcp192.168.1.2 33891 10.0.0.1 3389     extendable。其中192.168.1.2是要映射的内网地址。第一个3389就是内网端口。而 10.0.0.1就是外网的IP。那么第二个3389就是外网的端口。

思科2811路由器常见问题指令：Access-enable允许路由器在动态访问列表中创建临时访问的列表入口。Access-group把访问的控制列表应用到了接口上。Access-list 定义一个标准的IP ACL。Access-template  在连接的路由器上手动替换临时访问列表入口

ip nat inside source static tcp 221.131.44.150 80 192.168.0.88 80
