How to setup MongoDB behind Nginx Reverse Proxy [closed]

You’re right, you need to use NGINX’s stream module by adding a stream section to your .conf file:

stream {
    server {
        listen  <your incoming Mongo TCP port>;
        proxy_connect_timeout 1s;
        proxy_timeout 3s;
        proxy_pass    stream_mongo_backend;
    }

    upstream stream_mongo_backend {
      server <localhost:your local Mongo TCP port>;
  }
}
