OpenVPN over UDP, or User Datagram Protocol, is usually faster than TCP because it lacks the error correction feature. Web technologies that depend on real-
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). If the VPN uses TCP, then your own TCP connections will use IP packets sent through the VPN, so you end up paying the TCP overhead twice. An UDP-based VPN thus has the potential for slightly better performance. On the other hand, the cryptographic protection of the VPN requires some state management, which may be harder for the VPN UDP sera plus rapide, quand TCP sera un peu plus sécurisé en théorie, mais maintenant que tu mets en place du VPN, la sécurité est incluse dans le VPN. Donc UDP plus rapide, et souvent plus adapté. 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. 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
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.
