Flame Proxy

You need to go to "Settings", under "Sharing" select "VPN". And there you can either enter the connection parameters manually (address, port number, username and password), or choose a program that automatically connects the user to the proxy (free applications of this type can be found in Google Play).

If your Java UDP server does not accept more than one packet, there might be an issue with the way you are handling incoming packets or with the network configuration. To troubleshoot and resolve this issue, you can follow these steps:

1. Check your server code to ensure that it is correctly handling incoming packets. Make sure you are not accidentally discarding or overwriting packets.

2. Verify that there are no firewalls or network configurations blocking the UDP packets. UDP is a connectionless protocol, and packets may be dropped by firewalls or routers if they are not allowed.

3. Ensure that the client is sending packets correctly. Check if the client is using the correct IP address and port number for the server, and that it is not sending packets too quickly, causing them to be dropped or lost.

4. Increase the buffer size of the UDP socket in your server code. By default, the buffer size is often too small to handle multiple packets efficiently. You can increase the buffer size by using the setSoTimeout() method on the DatagramSocket object. For example:

DatagramSocket serverSocket = new DatagramSocket(port);
serverSocket.setSoTimeout(timeout); // Set a timeout value in milliseconds

5. Implement a multithreaded or asynchronous server to handle multiple incoming packets simultaneously. This will allow your server to accept and process multiple packets at the same time. Here's an example of a multithreaded UDP server in Java:

import java.net.*;
import java.io.*;

public class MultithreadedUDPServer {
    public static void main(String[] args) throws IOException {
        int port = 12345;
        DatagramSocket serverSocket = new DatagramSocket(port);
        while (true) {
            byte[] receiveBuffer = new byte[1024];
            DatagramPacket receivePacket = new DatagramPacket(receiveBuffer, receiveBuffer.length);
            serverSocket.receive(receivePacket);
            handlePacket(receivePacket, serverSocket);
        }
    }

    private static void handlePacket(DatagramPacket receivePacket, DatagramSocket serverSocket) throws IOException {
        byte[] sendBuffer = new byte[1024];
        InetAddress clientAddress = receivePacket.getAddress();
        int clientPort = receivePacket.getPort();
        int packetLength = receivePacket.getLength();
        System.arraycopy(receiveBuffer, 0, sendBuffer, 0, packetLength);
        DatagramPacket sendPacket = new DatagramPacket(sendBuffer, packetLength, clientAddress, clientPort);
        serverSocket.send(sendPacket);
    }
}

By following these steps, you should be able to resolve the issue with your Java UDP server not accepting more than one packet.

Select the "Proxy" tab in the "Network" window, then click on Win+C and find the "Settings" item. In the window that opens, stop at "Change computer settings" and go to "Network". Select the "Proxy" line here and disable the proxy functionality.

The main scenarios for using a proxy server: bypassing blocking, hiding the real IP, protection of confidential data when connecting to public WiFi access points, interaction with blocked applications, connection to closed portals, forums (which operate only in one country, region).

This depends directly on how the proxy server works. Some of them do not require any authorization at all, others require username and password for access, and others require you to view ads and so on. Which option will be used depends directly on the service that provides access to the proxy server.
