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.

Nowadays HTTPS can run above either TCP or UDP. The new "QUIC" protocol aims to replace multiple TCP connections with one multiplexed UDP connection, and hence can handle SSL and HTTPS: HTTPS → SSL → QUIC flow → UDP → IP. QUIC was originally developped in 2012 by Google and is undergoing IETF review. For more details, see Wikipedia.

Sans surprise, le système de communication employé par le TCP peut réduire la vitesse de connexion d’un internaute. L’UDP. Contrairement au TCP, l’UDP (abréviation de « User Datagram Protocol ») n’assure aucune vérification lors de la réception de données. En d’autres mots, un appareil utilisant ce protocole se limitera à l’envoi de paquets de données pour assurer la connexion. Sans conteste, cette réduction du …

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. Les informations ci-dessus concernent les réinitialisations d’un point de vue TCP et non UDP. The above information is about resets from a TCP standpoint and not UDP. UDP est un protocole sans connexion que les paquets sont envoyés de façon non fiable. UDP is a connectionless protocol and the packets are sent unreliably. Vous ne verrez pas la retransmission ou les réinitialisations lors Run it on both ;) I run instance on UDP 1194, and then one on TCP 443 for those places that have to bounce off a proxy or that might have UDP 1194 blocked. If the place has internet then almost always 443 will be open. But for performance you will normally want to be on UDP, but that can not work off a proxy, etc. So just run 2 instances.
