Cisco ASA 5505防火墙地址映射问题

基本情况:  

WAN: 221.221.147.195    Gateway: 221.221.147.200  LAN: 192.168.0.1

内网中有一台服务器,地址: 192.168.0.10    端口: 8089

故障描述:  内网可正常连接至服务器,外网无法连接.   端口映射出现问题.

解决方法:  命令行错误, 已更正并解决.

问题重点:  采用 "static (inside,outside) 221.221.147.195 192.168.0.10 tcp 8089" 映射.

目前配置如下:

在找寻解决方案过程中,有朋友做了重要提示, 采用: static (inside,outside) int 192.168.0.10 tcp 8089 做映射,但出现警告提示:

WARNING: static redireting all traffics at outside interface;

WARNING: all services terminating at outside interface are disabled.

后来将命令改成:  static (inside,outside) 221.221.147.195 192.168.0.10 tcp 8089   问题解决.

这几天又配置一个asa5505的防火墙 采用

static (inside,outside) 221.221.147.195 192.168.0.10 tcp 8089   不通。

后采用

static (inside,outside) tcp interface 8089 192.168.0.10 3389 netmask 255.255.255.255
