Go to "Control Panel" and in "Small icons" mode, find the item "Browser properties", aka "Internet Options". In the "Connection" tab, click on "Network Settings", and then leave the item "Automatic detection of parameters" enabled in the window that opens, and disable everything else.

It is a service that provides the ability to use a proxy server. It provides connection data (IP address and port number) as well as remote equipment that acts as a "gateway" for transferring traffic.

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.

The proxy settings in Zoom are configured through the regular Windows settings. To do this, you can use the command inetcpl.cpl in "Run". Next, you need to go to the "Connection" tab, click on "Network Setup". In the dialog box that opens, select "Proxy server" and set the required parameters. As a port, you can use 80 and 443.

In Key Collector settings, the user can specify parameters of the proxy server through which the program will connect to the network. In the application window, first select "Settings", then go to the "Network" tab and check "Use proxy". Its parameters can be set either manually or through a configuration file.
