Vpn use udp o tcp
In the ExpressVPN app, OpenVPN is actually referred to as “UDP” or “TCP,” two internet protocols that can greatly affect performance. 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. For most VPN users, UDP provides the best option for general use.

In most cases, UDP will do just fine. But if you want to, just head into the Settings menu in the FastestVPN app and switch to TCP. But, if VPN is blocked by an TCP option is more relaible offcourse, bcoz of TCP being connection oriented & reliable as compared to UDP being unreliable and non-connection oriented. Which ever you use, its just used as a wrapper fo original IPsec packet, so not much concern abt security, as these wrappers are removed completely, as packets go for decryption on either side o the tunnel. UDP is mainly used for online streaming and downloading. TCP is more reliable but also slightly slower than UDP and is mainly used for web browsing. You can watch our video for a more detailed explanation: Should I use UDP or TCP with OpenVPN? OpenVPN can run over either TCP or UDP transport protocols.

IP Passthrough uses DHCP to pass the IP address (and DNS server) that has been be transferred over TCP/IP, UDP or HTTP with the advantage of using 802.11 Using a VPN passthrough access point to connect to the cyberspace allows TCP vs UDP over an open VPN. The differences between them explained and how to choose the best one for your needs. Some VPN providers, however, prefer to let customers choose which connection protocol they prefer.

An UDP-based VPN thus has the potential for slightly better performance.
