To send a UDP request to a STUN server in C++, you can use the following example code. This example uses the boost::asio library for handling asynchronous I/O operations and boost::beast for handling UDP communication. Make sure you have the Boost library installed on your system before running this code.

#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 

namespace http = boost::beast::http;

using tcp = boost::asio::ip::tcp;
using udp = boost::asio::ip::udp;

int main(int argc, char* argv[]) {
  if (argc != 3) {
    std::cerr << "Usage: stun_udp_request  " << std::endl;
    return EXIT_FAILURE;
  }

  boost::asio::io_context ioc;
  udp::resolver resolver(ioc);
  udp::resolver::results_type results = resolver.resolve(argv[1], argv[2]);

  if (results.empty()) {
    std::cerr << "Cannot resolve: " << argv[1] << ":" << argv[2] << std::endl;
    return EXIT_FAILURE;
  }

  udp::socket udp_socket(ioc);
  udp_socket.connect(results.begin()->endpoint());

  // Prepare the STUN Binding Request
  std::string stun_request =
      "BINDING_REQUEST\r\n"
      "MIXED_RELAY\r\n"
      "USER-AGENT: STUN-UDP-Example\r\n"
      "\r\n";

  // Send the STUN Binding Request
  boost::system::error_code ignored_error;
  udp_socket.send_to(boost::asio::buffer(stun_request), results.begin()->endpoint(), 0, ignored_error);

  // Receive the STUN Binding Response
  boost::beast::flat_buffer buffer;
  http::response response;
  udp_socket.receive_message(buffer, response);

  // Print the STUN Binding Response
  std::cout << "STUN Binding Response:\n";
  std::cout << response.what() << std::endl;

  return EXIT_SUCCESS;
}

To compile the example, you can use the following command:

g++ -std=c++17 -o stun_udp_request stun_udp_request.cpp -lboost_system -lboost_as

Using a proxy in Telegram refers to the practice of routing your Telegram traffic through an intermediary server, known as a proxy server, to hide your IP address, bypass geographical restrictions, or improve security. There are several reasons why someone might use a proxy with Telegram:

1. Privacy and anonymity: By using a proxy, your real IP address is hidden, making it more difficult for Telegram or other users to track your online activities. This can be useful for maintaining privacy or avoiding potential harassment or stalking.

2. Bypassing geographical restrictions: Some Telegram features or content may be restricted based on your location. A proxy can help you bypass these restrictions by routing your traffic through a server in a different country, allowing you to access content that would otherwise be unavailable.

3. Security: Using a proxy can provide an additional layer of security by acting as a buffer between your device and the Telegram platform. This can help protect your account from potential hacking or unauthorized access.

To use a proxy with Telegram, you will need to configure the Telegram app to use the proxy server's IP address and port number. This can usually be done through the app's settings, under the "Data and Storage" or "Privacy and Security" section.

A proxy server is a kind of "mediator" between your equipment and a remote server (or the whole Internet). It can be used, for example, to swap your real IP address for another one, to bypass blocking. Proxies can also be actively used to intercept traffic (e.g. when testing created web applications).

First you should check if its characteristics are correct. Some proxy servers are just IP address and port number, others use so called "connection script". You need to double-check that the data was entered correctly.

There are several options for its use: bypassing the blocking of websites, shopping in foreign online stores at regional (local) prices, access to a full library of media content, hiding your real IP-address.
