Les inconvénients d’utiliser TCP avec OpenVPN : Les connexions sont plus lentes avec TCP que UDP, car elles vérifient chaque petit paquet de données pour s’assurer que rien ne manque et peuvent provoquer un flux de données plus lent, particulièrement si la source des données à un long chemin à parcourir. OpenVPN同时监听TCP和UDP端口 作者: 黄高明 日期: 2019-05-22 类别: vpn系列 标题: OpenVPN同时监听TCP和UDP端口 背景 因为公司是通过动态拨号上网，没有固定的外网地址，所以VPN是通过映射到内网来实现。 TCP & UDP both not connecting, help. Post by giratina143 » Fri May 01, 2020 6:46 am Here are the logs. Same for both I think. All other vpn services work, open is not working. Code: Select all. 2020-05-01 12:12:18 1 2020-05-01 12:12:18 ----- OpenVPN Sta OpenVPN 2.0 expands on the capabilities of OpenVPN 1.x by offering a scalable client/server mode, allowing multiple clients to connect to a single OpenVPN server process over a single TCP or UDP port. OpenVPN 2.3 includes a large number of improvements, including full IPv6 support and PolarSSL support. 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 und UDP im Vergleich. Beim TCP kann man sich sicher sein, dass die Daten, die man sendet, auch definitiv so ankommen, wie sie gesendet wurden, das heißt vollständig, in der richtigen Reihenfolge und nicht doppelt. TCP ist nicht paketorientiert, sondern schreibt eher in einem Stream.

The same openvpn process can't listen on UDP and TCP sockets at the same time. You have two good options: use two tap interfaces for openvpn. Have two openvpn server processes, one for each tap interface; one should listen on UDP, the other on TCP. Bridge these two tap interfaces on the server. use two tun interfaces. These can't be bridged, so if you want to share the IP space between TCP and

transport protocol (TCP/UDP) network errors others factors, which? There are a few specific questions that need an answer (feel free to add more): Maximum throughput using various parameters How does (excessive) packet loss affect performance? Does number of clients affect performance, if data transfer rate remains the same? (or "non-linear The OpenVPN protocol itself functions best over just the UDP protocol. Learn more about why we use both UDP and TCP here. TCP vs UDP over an open VPN. The differences between them explained and how to choose the best one for your needs.

Here are our results with OpenVPN over TCP: And OpenVPN over UDP: Pretty noticeable difference. Not all of you are going to get the same results, though. There’s a chance some of you might get better speeds with TCP instead of UDP. So you should do some tests before settling on a protocol to use. 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 The server log says it couldn't start openvpn because the port is already in use. You need to change the port 8080 you are running openvpn or the other server running there. Why don't you use the default 1194 port? (tcp should work if you can't use udp because it is blocked) – laurent Dec 11 '12 at 15:04
