TCP et UDP sont les deux protocoles principaux de la couche transport. Lors de la configuration d'un routeur ou d'une box internet, il n'est pas rare d'avoir Ă choisir entre les ports TCP et les OpenVPN Over UDP or TCP. Every top VPN provider offers you a choice of using OpenVPN with TCP or UDP. Which of the two you should pick ultimately boils down to speed and reliability, and whatâs more important to you. UDP is better for streaming, gaming, and real-time communication (both audio and video). With these applications, losing a packet here or there is not a big deal. But, having a When it comes to transferring data via VPN, the speed and reliability of the transfer depend primarily on the protocol that you use. There are two that you can choose from â Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).If you've used any good VPN app from providers such as ExpressVPN, CyberGhost or NordVPN as well as many others you'll find both options in the TCP, UDP, and OpenVPN. OpenVPN, the VPN protocol that the ProtonVPN Windows app and Linux command line tool are built upon, allows you to choose between TCP or UDP for your VPN connection. OpenVPNâs default is to use UDP simply because it is faster. The smart protocol selection feature, available on version 1.9.2 and later of the Windows app UDP is mainly used for online streaming and downloading. TCP is more reliable but a little slower than UDP and usually used for web browsing. You can watch our video for a more detailed explanation: For most VPN users, UDP provides the best option for general use. The typical recommendation is to start with UDP. And if you experience issues with the connection, try the TCP protocol. Some of the potential problems that may keep you from connecting to a VPN with UDP include: Countries or ISPs blocking UDP ports to prevent VPN connections TCP VPN pros: TCP connections are usually allowed in restricted networks on common ports like 80, 443, while UDP traffic may be blocked, usually in corporate networks. Moreover, it is fairly common for ISPs to throttle UDP traffic; TCP VPN cons: usually, a TCP VPN connection is slower than UDP, so you should prefer UDP connections with a VPN
TCP vs. UDP (In-depth Look) So what is the difference between TCP and UDP, exactly? We took a quick look at their differences before, but letâs see what they all mean. Weâre not going to discuss UDP vs. TCP applications, though, since theyâre pretty straightforward. What we mentioned in the table at âUsed Forâ pretty much sums it all up.
Those protocols are almost all TCP-only and not UDP. On such networks it's useful to also support TCP connections, even though this is less ideal due to the possibility of the TCP Meltdown phenomenon. But given the choices between something that works reasonably well or not at all, we've chosen to be practical and also support TCP. By default we choose the port TCP 443 which is the same port

Bien qu'on puisse le configurer pour marcher sur tous les ports, OpenVPN fonctionne mieux sur un port UDP, qui est gĂ©nĂ©ralement plus rapide. ExpressVPN utilise UDP par dĂ©faut, sauf s'il est bloquĂ©.

These ProtonVPN apps can use the OpenVPN VPN protocol, which supports both the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP). These two protocols determine how the packets of data that make up your online traffic are sent from your device to the VPN server.
Are the UDP and TCP protocols compatible with VPN services? Yes. They both work with OpenVPN, an open-source VPN protocol used by many leading VPN providers, including NordVPN. OpenVPN runs on both network protocols and they both provide privacy and security. Which one to choose depends on what youâre using your VPN for. TCP is more reliable, so you may think that TCP is the best option, but TCP vs. UDP (In-depth Look) So what is the difference between TCP and UDP, exactly?

OpenVPN over TCP vs UDP. Many VPN providers support OpenVPN in their apps and allow users to select between the TCP and UDP protocol. Itâs important to note that neither of them are superior to the other and the difference isnât even noticeable to most end users. Generally, UDP offers better speeds, but it can vary on a scenario-by-scenario basis. In some cases, either one of the protocols

Open VPN is a type of software application. It helps to create P2P and S2S connection. P2P means point to point connection and S2S means site to site connection. These connections are set by implying VPN or Virtual Private Network. In Open VPN there are two types of protocols are used one is TCP and other is UDP. TCP means Transmission Control ⊠Entre ton client et serveur VPN, les paquets TCP/UDP/whatever sont encapsulĂ©s dans des paquets UDP. Une fois sortie du serveur, tes paquets sont dĂ©sencapsulĂ©s.
