In addition, it supplies a way to safe the data site visitors of any given application applying port forwarding, in essence tunneling any TCP/IP port about V2Ray DNS. Which means the appliance knowledge site visitors is directed to flow within an encrypted V2Ray DNS connection making sure that it can not be eavesdropped or intercepted even though it is actually in transit. V2Ray DNS tunneling permits adding community safety to legacy programs that don't natively support encryption.
