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.
OpenVPNは、比較的新しく構成可能なプロトコルです。ExpressVPNのバージョンは、UDPポートとTCPポートの両方をサポートしています。 UDPは、User Datagram Protocolの略です。OpenVPNは、どのポートでも動作するように設定できますが OpenVPN utilise le port UDP 53 et le port TCP 80 pour la transmission. En outre, il peut également transmettre des données via d'autres ports TCP de la plage 5500 - 55000. En outre, il peut également transmettre des données via d'autres ports TCP de la plage 5500 - 55000. 但是使用 udp 的话会有一个问题，那就是如果 VPN 两端之一断开了连接，由于 udp 在断开时不管是正常断开还是异常崩溃都不会向另一端发送通知，那么连接双方的连接感知必须通过一个心跳来完成，在 OpenVPN 中可以通过 --ping 和 --ping-restart 来配置，如果心跳时间过短，虽然感知力增加了，但是心跳 TCP, UDP, and OpenVPN. 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 In OpenVPN, you can choose either UDP or TCP connection types. Using IPsec and WireGuard, it is always UDP and can’t be changed. If you are connecting from a restricted network where protocols and ports are blocked, try OpenVPN over TCP ports such as 443, 80.
I also really need the OpenVPN UDP because I have several networks and I have to keep only linux machines to meet the VPNs being that I could do that in RB1100, using TCP is slow and cumbersome, consuming too much CPU. help much if there was a preview for this. sds Marcelino Viana Pinheiro MVP Technologies Corp + 55 41 35261227 + 55 41 84188001
The OpenVPN protocol itself functions best over just the UDP protocol. And by default the connection profiles that you can download from the Access Server are preprogrammed to always first try UDP, and if that fails, then try TCP. Unfortunately, on some more restrictive networks, all traffic except very commonly used ports are simply blocked. Bottom line: UDP should be the main choice when using a VPN. In OpenVPN, you can choose either UDP or TCP connection types. Using IPsec and WireGuard, it is always UDP and can’t be changed. If you are connecting from a restricted network where protocols and ports are blocked, try OpenVPN over TCP ports such as 443, 80. Both UDP and TCP divide your data into smaller units called data packets. These include the sender and receiver’s IPs, various configurations, the actual data you are sending, and the trailer – the data that indicates the end of the packet. The only difference between the two protocols is … OpenVPN crée un tunnel TCP ou UDP et ensuite chiffre les données à l'intérieur de celui-ci. Le port par défaut utilisé par OpenVPN est le port UDP 1194, basé sur un assignement officiel de port par l'IANA.
OpenVPN nos permite utilizar tanto el protocolo TCP como UDP para el túnel de datos, tal y como habéis visto, TCP y UDP son muy diferentes, y siempre es recomendable utilizar TCP ya que dispone de control de flujo, control de congestión, control de errores y muchas otras características que hacen que una conexión sea fiable. Si vais a usar OpenVPN, de manera predeterminada se utiliza UDP

In this post, I’m going to talk about optimizing the said tunnels to get the most out of them. Believe it or not, the default OpenVPN configuration is likely not optimized for your link. It probably works but its throughput could possibly be
