These ProtonVPN apps can use the OpenVPN VPN protocol, which supports both the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP). These two protocols determine how the packets of data that make up your online traffic are sent from your device to the VPN server.
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. OpenVPN is a relatively new and highly configurable protocol. ExpressVPN’s version supports both UDP and TCP ports. UDP stands for User Datagram Protocol. Though it can be configured to run on any port, OpenVPN runs best on a UDP port, which is generally faster. ExpressVPN uses UDP by default Jul 12, 2020 · The UDP protocol functions in almost the same way as TCP, with a few differences concerning all the extra steps that TCP takes in order to guarantee maximum reliability. Pros: Best effort protocol, delivering a lightweight and considerably faster connection speed
The VPN will take the traffic, TCP or UDP and wrap it in its own VPN protocol, which as you see above, has the option of being TCP or UDP. You could, therefore, have a HTTP session that uses TCP being wrapped in UDP packets being sent over the VPN.
OpenVPN is pretty notorious for slowing down original ISP speeds, so many VPN users prefer to use it over UDP to get a smoother experience. Our advice is to use OpenVPN over TCP for important stuff – online browsing, emailing, chatting with friends, Internet banking, downloads, and other stuff like that.
