nacos远程部署，公共服务远程部署，本地服务启动后，访问不了

一、该问题的重现步骤是什么？

1. 远程（外网ip）部署nacos

2. 远程（外网ip）启动公共服务（用户、鉴权、日志、系统、网关）

3. 本地（内网）启动demo服务

二、你期待的结果是什么？实际看到的又是什么？

我期待：能通过远程（公网ip）的nacos、网关访问内网的demo服务

实际：不能访问，因为内网的ip不是公网ip

补充：公网的服务访问可以正常，就是demo不能访问。实际开发需要将公共服务部署到公网，与内网的服务进行协作开发。

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

任何版本都存在这个情况

跟操作系统、产品和版本没有关系

四、请提供详细的错误堆栈信息，这很重要。
