I have many esp8266 that works as WEB-servers, they have a unique port and IP address. I need to create another MAIN Gateway that could manage all my existing ESP8266 web-server modules without the need of opening many ports for each of my WIFI modules. Some other developer suggested star topology, and other MQTT. But I do not want to change my HTML web-server built-in modules because they work perfect. The only need is to manage many like 50pcs or 100pcs by using a Gateway connected to home router.
