Question

I have two instances of nginx server running one with corporate ip and second with internal ip .I want a link from external nginx get redirected to internal nginx server and use external nginx as gateway. Also need to make sure that internal nginx running on dynamic IP

Tried to use variable for dynamic IP as shown in code snippet

 location /route/(?<section>.+){
      proxy_bind 172.31.*.*;
      proxy_pass http://$section/single-table-view;
      proxy_set_header Host $http_host;
}

You need to configure nginx as mentioned below:

If you want to redirect your External nginx to Internal nginx you should configure your External server like:

server {
        listen 80;
        listen [::]:80;
        server_name domain_name;

        location / {

                proxy_pass http://InternalNginxIpAddress:PortYouWant;

                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
        }
}

Now each request from External nginx will be forwarded to Internal nginx, where your Internal nginx server is set as

proxy_pass http://localhost:PortYouWant;
