Both Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are protocols for sending data packets through the internet built on top of the Internet Protocol. 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 using UDP first. But you 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 Avec un bon service VPN, vous aurez fréquemment la possibilité d’utiliser le mode TCP ou UDP pour votre connexion. En outre, tout fournisseur qui utilise OpenVPN, le standard de l’industrie, aura la possibilité de passer d’un protocole à l’autre.

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.

TCP VPN cons: usually, a TCP VPN connection is slower than UDP, so you should prefer UDP connections with a VPN; higher latency in case of packets lost (unstable network connections) UDP VPN pros: usually faster speeds on UDP VPN connections vs. TCP VPNs. UDP is ideal for video/audio streaming, gaming and P2P traffic; lower latency makes it the
