The protocol V2Ray operates in two modes.
How a proxy server redirects traffic through HTTP or SOCKS proxy, and allows flexible routing configurations for specific IPs or domains. It does not require the creation of a separate network interface, and operates at the application level or as a system proxy. Typically, in such a mode on Windows devices, the IP changes only in browsers.
Also, it can be run as a VPN. Often this mode is called TUN. In this case, a virtual interface is created through which all the network traffic of the device connected to the VPN is routed. This interface is added to the device's network configuration.
