What is a UDP Proxy?

In this post, we will be answering the question – what is a UDP proxy?

But before we proceed, we need to take a look at what UDP is all about and then the UDP proxy and its applications.

Notably, UDP is used in real-time communications for sending time-bound voice and video traffic. A practical application of UDP is the Voice over IP (VoIP) calls commonly used for internet-based calls, which sometimes is a better option because there’s no delay in transmission between the sender and the receiver.

Although UDP has drawbacks, we will be exploring its usefulness and how you can harness the full potential of UDP using UDP proxy.

What is User Datagram Protocol? How does it work?

UDP is an acronym for User Datagram Protocol, which was designed by David Reed in 1980. It is used for sending messages known as Datagrams across the Internet Protocol network without going through a handshake, error check, and flow control.

Also, UDP is a fast means of communication because it works without requiring ‘handshake.’ Hence, it favors a fast data transfer between the sender and the receiver. However, it is also prone to exploitation due to its connectionless mode.

Unlike TCP, UDP cannot check for error and ordering functionalities. Therefore, it is preferable in situations where speed is given priority over error checking.

How Does the UDP Work?

UDP works by using the Internet Protocol (IP) to send messages known as datagram to an IP address or a host from another IP address or computer.

Besides, UDP encloses a datagram (a data unit) in a UDP packet and also adds its header information to the UDP packet.

The data enclosed in a UDP packet include the following:

  • The sender and receiver ports

  • Packet length and size

  • A checksum

Usually, a UDP packet is enclosed in an IP packet before sending it to the recipient IP address or host.

However, not all UDP packets sent over an Internet Protocol gets delivered to the right recipient because, unlike TCP, UDP does not make a direct connection with the receiving computer.

Hence, there may be packet loss between the sender computer and the recipient computer.

Also, UDP-based apps wait for responses from the recipient. If there’s no response from the recipient IP or computer within a limited time-frame, the UDP-based app assumes the packets are lost, and it resends the UDP packets to the recipient. After several repeated trials, it stops sending UDP packets to the recipient.

Despite UDP’s unreliable transmission method, it is still a preferable option because of its fast delivery time, and it is quite suitable for services like Voice over IP, IP streaming, etc. due to its low overhead.

Characteristics of UDP

  • UDP is faster than TCP because it needs far lesser resources to establish a connection.

  • Data packets delivery is not orderly

  • It is a connectionless protocol

  • Some packets can be missing without distorting the message.

  • It is preferable for applications that require high-speed and efficient transmission, e.g., games and VoIP services.

Use Cases of User Datagram Protocol

Since UDP does not subject data to error checks, avoid overhead associations, and also retransmits missing packets, it makes UDP ideal for real-time applications that don’t require data correction or verification.

Therefore, User Datagram Packet is useful in the following real-time applications:

Games and gaming apps are real-time applications that require the transmission of highly time-sensitive data. For games that require player movements and weapon firing, it is critical to consider the data transmission speed in such cases.

Also, bandwidth plays a crucial role in gaming to prevent a slowdown in multi-player gaming. This is essential to avoid lagging, which can eventually result in extreme difficulty in playing the game.

  • Video conference

Several applications like VoIP and Internet Protocol Television uses UDP for data transmission because negligible data loss is quite significant. Using TCP instead of UDP in such applications can result in a noticeable delay in the relayed sound or video.

  • Online Streaming

UDP plays an essential role in streaming videos. This is because the human eye can only register 30 frames per second. This makes it very difficult for a human to observe minor errors that might occur during streaming.

Hence, UDP sends messages that allow your movie to start playing without using up bandwidth to check for errors and retransmission of data packets, which are not useful when they are transmitted because such packets are already outdated.

  • Advanced applications

UDP plays a vital role in aircraft controls and flight instruments. For example, UDP is used in the Real-time Operating systems of ARINC 664 standard.

Furthermore, some apps do not need a TCP transmission because they handle reliability by themselves; hence, these apps make use of UDP as their Transport Layer Protocol.

For instance, the Trivial File Transfer Protocol (TFTP) uses UDP for transmission. Also, it has a mechanism for checking for errors, flow control, retransmission, and acknowledgments.

To transmit large amount of data over a short period of time without hassles, a UDP proxy is usually required.

What is a UDP Proxy?

A UDP proxy (UDPXY) is a gateway which ensures data transmission between any UDP-based applications to internet-enabled devices. It facilitates end-to-end data stream relay, which allows internet users to access multicast.

With a UDP Proxy, you can stream content of a multicast UDP-dependent IPTV when using an incompatible player or streaming client. Besides, the UDP proxy electronically transmits the UDP data packets over the internet through an HTTP connection.

UDP proxy is suitable for usage on popular non-compatible multicast players such as VLC player, MPlayer, XBMC, and FFmpeg. Not to mention, UDP proxy can also be used for advanced applications such as VoIP, video conferencing, live streaming, instant messaging, and more.

With an ideal UDP proxy, you can stream from IPTV or multicast directly on smartphones, smart TVs, PCs, game consoles, and any other internet-enabled devices.

Benefits of Using UDP Proxy

  1. UDP Proxy bypasses internet blocks

UDP Proxy helps you to bypass the restrictions imposed by web services. Take, for instance, if your IP address is blacklisted on a UDP-dependent application, a UDP proxy will route your traffic to bypass the restriction.

  1. No traffic or protocol limitations

A UDP proxy is quite flexible and secure; hence, you can stream unlimited content over the internet. Besides, UDP proxy is a low-level proxy that can handle any type of program, protocol, or traffic.

  1. UDP Proxy gives you faster and more reliable connections

Using a UDP proxy ensures that you have a stable connection with an efficient performance. Since a UDP doesn’t perform checks on the packets delivered; therefore, it requires less time and effort to convert datagrams to a stream of fixed data packets. This ensures you are provided with an ultra-speed and reliable connectivity.

  1. UDP proxy ensures a lower error rate and better performance

Rewriting datagram headers can result in a high error rate and a high chance of re-routing data packet or mislabelling the packet data. However, a UDP proxy does not need to rewrite headers, so there is a higher performance rate and a lesser chance of making errors.

  1. Improved performance of P2P platforms

A UDP proxy is faster than other types of proxies because a UDP proxy transfers data packets in bits. For a fast download rate, UDP proxy is perfect for P2P streaming.

SOCKS and UDP Internet Protocol Connection

SOCKS is an Internet Protocol for routing data packets or datagrams between a server and a client via a proxy server.

Routing your data traffic through a proxy server generates a false IP address to mystify your IP address before the data packet gets to the receiver. In the same vein, SOCKS uses proxy servers to create UDP connections via a fake IP address.

Assuming your IP address is 10.101.1. 01, your data traffic will be channeled through a SOCKS proxy with a different IP address (usually generated). Hence, the recipient (website server) will assume the data traffic is coming from your SOCKS proxy; therefore, the website server cannot have access to your original IP address or block your internet connection.

To sum it up, using a UDP proxy with SOCKS Internet Protocol provides you with the benefits of being anonymous while online.

Therefore, it is vital to use a proxy service provider that supports SOCKS to set up your UDP-dependent applications. A perfect example of a reliable proxy service provider that supports SOCKS is ProxyRack.

How to Set up a UDP Proxy

Your internet-enabled device uses ‘ports’ to communicate with various web-based apps, websites, and internet-based services.

It is interesting to note that your Operating System has specific ports for communicating with the above-listed web services.

Nevertheless, any website or web-based app will communicate with your PC or other internet-enabled devices through a connection port, either a TCP or UDP. Besides, these two protocols allow the communication exchange with your computer.

How to use UDP as your Port Protocol instead of TCP

To enable UDP as your port protocol on Windows PC, follow these steps:

  • Access your PC’s control panel by typing ‘Control Panel’ in the Windows search bar.

  • Click on ‘System and Security’.

  • Click on ‘Windows Firewall’.

  • Now, select the option that says ‘Allow a program through Windows Firewall.’

  • Click on the ‘Add port’ icon and assign a name to the UDP port.

  • Enter the port number and then tick the UDP check-box.

  • Click ‘OK’ to save changes.


User Datagram Protocol is an internet protocol for sending time-sensitive transmissions over the internet to an IP address or a host. On the other hand, UDP proxy facilitates data transmission from UDP-dependent applications to internet-enabled devices without restrictions.

With an excellent UDP proxy service provider such as ProxyRack, your PC can establish a connection with any website server, web-based applications, or services from any location in the world.

Besides that, ProxyRack gives you advanced customization options when it comes to sending and receiving data packets via UDP.
