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 basis. In some cases, either one of the protocols OpenVPN Robust and flexible VPN network tunnelling Brought to you by: dazo, ericcrist , jimyonan 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. 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). 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 à choisir entre les ports TCP et les 04/01/2015 SSTP uses a highly secure SSL 3.0 encryption. It uses TCP port 443 which means that it can bypass most firewalls. Though SSTP is a primary proprietary from Microsoft, so it is pretty compatible with Windows, it is quite remarkable how well it performs in encrypting the data and ensuring privacy.

In some instances, you may need to manually find the MTU of you link first. TCP tunnels usually don’t require such adjustments. link-mtu.
