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.
