The list of cons includes: The setup uses TUN/TAP devices. The Security Setup Server Security

That would change the game completely. Open Happiness Let’s take a simple example – an advertisement from Coke. The advertisement states that a coke bottle denotes opening happiness. The Antidote The antidote is do exactly the opposite. Photo Courtesy: roosanaa on Flickr
