Cisco ASA 5510 端口映射
WAN: 221.221.147.195 Gateway: 221.221.147.200LAN: 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
