2017-03-22

cisco思科是全球领先的大品牌,相信很多人也不陌生,那么你知道Cisco ASA 5505防火墙地址映射问题吗?下面是小编整理的一些关于Cisco ASA 5505防火墙地址映射问题的相关资料,供你参考。

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.
