TCP parce que c'est la seule solution si on veut chiffrer le vpn avec SSL. UDP sinon parce que : * TCP sur TCP peu performant * UDP sur TCP n'apporte rien au schmilblick (voir peut casser les performances d'une application de streaming prévue exprès pour ne pas retransmettre). 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 implementation when using UDP, hence it is possible … OpenVPN Over UDP or TCP.

But, having a UDP is mainly used for online streaming and downloading. TCP is more reliable but a little slower than UDP and usually used for web browsing. You can watch our video for a more detailed explanation: OpenVPN: Difference between TCP and UDP . Open VPN is a type of software application. It helps to create P2P and S2S connection. P2P means point to point connection and S2S means site to site connection. These connections are set by implying VPN or Virtual Private Network. In Open VPN there are two types of protocols are used one is TCP and other is UDP. TCP means Transmission Control …

16 May 2019 Learn what the differences between UDP and TCP servers are and how to switch between the them using the FlashRouters Privacy App.

UDP and TCP are two protocols that are responsible for determining how data is exchanged on the internet. Since both are built on the IP protocol, they do share similarities. However, their differences make them suitable for different use cases. Regardless of their similarities and differences, UDP and TCP are among the most widely used protocols. Now, if you are not sure which one to opt for VPN 原理及实现之TCP还是UDP. 有了 ip over ssl 的关键思想，OpenVPN 就是一个必然结果了，于是就不多说了，OpenVPN 和 OpenSSL 并不在一个层次上，虽然都很 open。OpenVPN 的配置非常复杂，主要就是为了建立更加合理的隧道，虽然 IPSec 实现的 VPN 不区分客户端和服务器，建立 sa 的时候全靠 dh 对称 … 17/12/2018 Ivacy uses TCP port as default. UPD: It stands for User Datagram Protocol and can be easily configured to run on any port. If configured, Open VPN functions seamlessly with a UDP port and thus, is fast. Although, OpenVPN on UDP is fast but a less reliable protocol as it does not guarantee the delivery of packets. It is a good protocol for

つまり、tcpとudpの違いは、「コネクションを確立するかどうか」ということだけです。その他の特徴や用途、上位プロトコルなどは、コネクションを確立した結果、信頼性が高くなる（またはその逆）コネクションを確立するから、転送速度が遅くなる（またはその逆）

By default, the TCP connection timeout is 15 minutes and the UDP connection timeout 30 seconds. In order to increase the connection timeout you can modify it from the firewall access rules. NOTE:The following scenario describes how to modify the TCP connection timeout for a Site-to-Site VPN between 2 SonicWalls. RESOLUTION: Entre ton client et serveur VPN, les paquets TCP/UDP/whatever sont encapsulés dans des paquets UDP. Une fois sortie du serveur, tes paquets sont désencapsulés. Et tu retrouve ton paquet de base. CEO - co-founder @ particule.io. Awks 28 septembre 2013 à 17:11:30. Merci à toi aussi pour ta réponse .
