3 Jul 2017 You've probably seen references to TCP and UDP when setting up port- forwarding on a router or when configuring firewall software. These two 

16/09/2018 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 TCP is more reliable, so you may think that TCP is the best option, but there are times when UDP might be preferred. There is an option within the OpenVPN application that allows selection of a TCP-based connection, however if you find it becomes necessary to use TCP - we recommend using SoftEther or L2TP (L2TP is a TCP-based client offering flawless connection for mobile devices in particular). 28/04/2009 OpenVPN: Difference between TCP and UDP . 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 … SSL VPN over UDP still attempts to connect to the VPN server on port 443, but unlike HTTPS traffic that uses TCP as a transport protocol, it uses UDP. Some firewalls and proxies may flag this as suspicious and drop the traffic. It can also be seen as peer-to-peer traffic (which it actually is) and again be dropped. Very often with a good VPN service, you will have the option to use TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) mode for your connection. Furthermore any provider that uses the industry standard ‘OpenVPN’ will have the option to switch between both protocols. The problem is most people have a hard time understanding all this networking jargon.

Говорят, есть люди, считающие, что для vpn tcp заруливает udp. Правда, лично я ни одного такого товарища живым не видел Сам юзаю tcp для vpn только когда надо пройти через connect/socks прокси. В остальных

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. OpenVPN’s 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, will always attempt to establish a connection 21/07/2020 TCP vs UDP : C’est quoi la différence ? La réponse dépend vraiment de votre propre utilisation et de vos besoins en matière de sécurité. Aucune des deux options ne remplace l’autre car on les utilise tous les deux, mais dans des cas spécifiques. TCP (Transmission Control Protocol) Commençons par le plus ancien, TCP/IP est le protocole utilisé actuellement dans le monde entier. Les
