内网配置nat123端口映射,外网连接内网MYSQL数据库
使用nat123,实现外网直接连接访问内网mysql数据库。
1.明确内网连接mysql数据库地址
确定内网MYSQL数据库IP(192.168.1.240)端口(3366)。
注意,mysql数据库的默认端口是3306,示例端口是3366。
确定内网连接MYSQL数据库正常,示例以SQLyog工具连接mysql数据库
2.nat123端口映射
在内网登录nat123。(第一次添加映射需要在内网登录)
添加映射,内网地址(mysql数据库内网地址192.168.1.240),
内网端口(mysql数据库内网端口3366),
外网网址(为空),外网端口(33660,可外网访问mysql数据库端口)。
确认保存提示添加映射成功后,关闭添加映射窗口,查看端口映射列表。
显示新添加端口映射信息。
此映射显示的外网网址(113.10.159.162)是自动分配的公网IP。
映射图标显示小笑脸说明映射服务正常,
当前可通过外网(113.10.159.162:33660)直接连接内网MYSQL数据库。
至此,只要不关闭不退出映射服务,即可在外网直接连接内网MYSQL数据库。
