To count the number of lost packets over UDP, you can use a combination of network monitoring tools and custom scripts. Here's a step-by-step guide to help you achieve this:

1. Install a network monitoring tool:

You can use a network monitoring tool like Wireshark, tcpdump, or ngrep to capture the UDP packets on your network. These tools allow you to analyze the packets and identify lost packets.

2. Capture UDP packets:

Use the network monitoring tool to capture the UDP packets on the interface where the communication is taking place. For example, if you're monitoring a local server, you might use tcpdump with the following command:

tcpdump -i eth0 udp and host 192.168.1.100

Replace eth0 with the appropriate interface name and 192.168.1.100 with the IP address of the server you're monitoring.

3. Analyze the captured packets:

Once you have captured the UDP packets, analyze them to identify the lost packets. You can do this by looking for the sequence numbers in the UDP packets. If the sequence number of a packet is not consecutive to the previous packet, it means the packet was lost.

4. Write a custom script:

You can write a custom script in a language like Python to parse the captured packets and count the lost packets. Here's an example of a simple Python script that counts lost packets:

import re

def count_lost_packets(packet_data):
    sequence_numbers = re.findall(r'UDP, src port \((\d+)\)', packet_data)
    lost_packets = 0

    for i in range(1, len(sequence_numbers)):
        if int(sequence_numbers[i]) != int(sequence_numbers[i - 1]) + 1:
            lost_packets += 1

    return lost_packets

# Read the captured packets from a file
with open('captured_packets.txt', 'r') as file:
    packet_data = file.read()

# Count the lost packets
lost_packets = count_lost_packets(packet_data)
print(f'Number of lost packets: {lost_packets}')

Replace 'captured_packets.txt' with the path to the file containing the captured packets.

5. Run the script:

Run the script to count the lost packets. The script will output the number of lost packets in the captured data.

UDP Hole Punching is a technique used to establish a connection between two devices behind NAT (Network Address Translation) firewalls. It works by exploiting the fact that some UDP packets can still pass through the NAT firewall even if the source and destination ports are the same. However, UDP Hole Punching does not always bypass NAT for several reasons:

1. Symmetric NAT: In symmetric NAT, both the source and destination ports are translated, and the NAT firewall maintains a table of active connections. If the table is not updated correctly, UDP hole punching may not work.

2. Unstable NAT: Some NAT firewalls are known to be unstable, causing them to drop packets or change their behavior unexpectedly. This can lead to failure in establishing a connection using UDP hole punching.

3. Firewall rules: Some NAT firewalls have strict rules that prevent UDP hole punching from working. For example, if the firewall is configured to block all incoming UDP traffic, UDP hole punching will not be successful.

4. Timeout: NAT firewalls have a timeout for their connection tables. If the timeout occurs before the connection is established, UDP hole punching will fail.

5. Network congestion: If the network is congested, packets may be dropped or delayed, causing UDP hole punching to fail.

In summary, while UDP hole punching can be an effective technique for bypassing NAT, it does not always guarantee a successful connection due to various factors such as NAT behavior, firewall rules, and network conditions.

It means a proxy server for devices that connect to the router via WiFi. It is also a remote server to let traffic through. For example, a user sends a request to Netflix from his smartphone through a proxy that is hosted in the UK. Netflix servers will "recognize" such a user as being from the UK (regardless of his actual location).

"Work via VPN" means to connect to a site, an application or a remote server via a VPN server. That is, through an "intermediary" that not only hides the real IP address, but also additionally encrypts the traffic so that it cannot be "read".

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.
