Should I leave it at default 1194 UDP? or change to a more common at - then sure you could have your vpn listen on this port and create a 

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). 16/09/2018 · Both TCP and UDP are protocols used for sending bits of data — known as packets — over the Internet. The main difference between TCP and UDP is the way these packets are delivered. OpenVPN est un protocole relativement nouveau et très configurable. La version utilisée par ExpressVPN supporte les ports UDP et TCP. UDP signifie User Datagram Protocol, ou protocole de datagramme utilisateur. Bien qu'on puisse le configurer pour marcher sur tous les ports, OpenVPN fonctionne The trade-offs between TCP and UDP (regardless of VPN usage) is always the same: You sacrifice speed for reliability as UDP is connectionless and the server sending the data theoretically (depending on the implementation) doesn't care if it reaches the destination or not. This is fine in things like Internet gaming where each packet might be a movement by a user, but in things like encryption Il doit être installé aux deux extrémités du VPN, une est désignée comme serveur, l'autre comme client. TUNNELLING OpenVPN crée un tunnel TCP ou UDP et ensuite chiffre les données à l'intérieur de celui-ci. Le port par défaut utilisé par OpenVPN est le port UDP 1194, basé sur un assignement officiel de port par l'IANA. Vous pouvez

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 – 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

You may see UDP and TCP related to VPN’s. What do they do, and how will it change how a VPN works. This short guide shows the difference between UDP and TCP. TCP parce que c'est la seule solution si on veut chiffrer le vpn avec SSL. UDP sinon parce que : * TCP sur TCP peu performant * UDP sur TCP n'apporte rien au schmilblick (voir peut casser les performances d'une application de streaming prévue exprès pour ne pas retransmettre). Sinon dans ce que tu dis : * je ne comprends pas ton histoire de scanner * la perte de paquets n'a rien a voir avec OpenVPN est un protocole extrèmement versatile et flexible. Il a été conçu pour de multiples usages avec le maximum d'ouverture. La configuration habituelle d'OpenVPN utilise le protocole UDP et le port "standard" 1194 assigné par l'IANA. Toutefois rien n'empêche de configurer OpenVPN pour fonctionner sur n'importe quel autre port et même utiliser le protocole TCP si nécessaire.

OpenVPN over TCP vs UDP. Many VPN providers support OpenVPN in their apps and allow users to select between the TCP and UDP protocol. It’s important to note that neither of them are superior to the other and the difference isn’t even noticeable to most end users. Generally, UDP offers better speeds, but it can vary on a scenario-by-scenario
