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
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.

OpenVPN is a popular open-source software package used for VPN connections. It relies on UDP and TCP protocols for transmitting data across secure VPN tunnels. UDP and TCP are both transport-layer protocols, required for establishing temporary connections between two programs, computers, or servers.
Re: Openvpn. У TCP больше накладных расходов на установку и поддержку соединений. UDP в данном случае будет работать быстрее. OpenVPN over TCP vs UDP.
