How to open ports for your internet server?

Question

Python

How to open ports of white ip address? It turns out that I open the port only gray, tk. only I can connect to the server from the server itself.
I try to connect through a regular browser - there is an answer. I try to connect via Tor or I ask a friend to connect to me - there is no connection.

In the router settings, I opened port 2000


In the windows firewall, I also opened port for incoming connections 2000


Server code:

from flask import Flask, request, jsonify
app = Flask(__name__)

@app.route('/price', methods=['GET', 'POST'])
def price():
    if request.method == 'POST':
        price = request.form['price']
        if int(price) < 1000:
            return jsonify({'msg': 'Нищий'})
        else:
            # Сюда алгоритм
            return jsonify({'msg': 'Вот тебе компьюдахтех'})
    else:
        return {'msg': '!'}

if __name__ == '__main__':
    app.run(host='0.0.0.0')

The server works on this ip (previously, I first tried to open port 5000, deleted all settings, and set it to 2000, although the server runs at 5000 at startup, strange)

Answer 1

Well, for starters, if there is no error, then the server is running on port 5000. Are you connecting to port 2000 via LAN?
Next - turn off the Windows firewall and antivirus in general, check
Do you even have an external IP from the provider? Have you subscribed to this service?
