FlyVPN currently supports UDP, TCP, and Socks5 protocols. The UDP protocol is best for online gaming; the TCP protocol is best for browsing websites and watching videos; the Socks5 protocol is a local proxy based on TCP protocol, which can allow only one browser to use the proxy without affecting the default network environment of other software.
