How to configure a nignx service reverse proxy for access by 3 IPs

场景：在10.17.55,44:7002和10.17.55.46:7003的weblogic 部署一个web工程，准备做负载均衡。在一台IP：12.17.56.44能访问到55.44和55.46上web工程的机器做nginx代理服务器，代理端口为7000，既12.17.56.44:7000能访问到10.17.55,44:7002或10.17.55.46:7003的web工程，而互联网有个IP22.18.55.33:7000 可以访问到，12.17.56.44:7000，12.17.56.44这台服务器的nginx.conf 内容配置如下：

#user  nobody;

#error_log  logs/error.log  info;

In the configuration file:

include /etc/nginx/mutnginx/*.conf; 

created two files similar to nginx.conf in the mutnginx directory.

nginx2.conf configuration is to allow other applications in the same network segment, namely 12.17.56.*, to access the web project with the same proxy IP. The configuration is as follows:

#user  nobody;
worker_processes  auto;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

is an Internet IP 22.18.55.33:7000 and intranet 12.17.56.44:5213 and 12.17.56.44: 7000 has been used as a mapping proxy, so these three IPs can access the web project.
