Post #109,726 by jbrabeck 7/15/03 10:13:07 AM Reply	Simple definition request My boss wants the definition and differences between PPP and VPN. I tried to explain, but she only became more confused. So, in simple, non-technical terms What is PPP and VPN? What is the difference between them?
Post #109,729 by boxley 7/15/03 10:25:47 AM Reply	VPN can ride on top of ppp Ponit to Point protocol allows 2 machines to act like there is a dedicated piece of copper line between them to pass signals. VPN Virtual Private Network is a tunnelling solution where 2 machines exchange encrpytion keys and pass ordinary traffic thru an encrypted tunnel. Someone watching the datastream going by could not determine what the traffic actually is. Hope that helps. thanx, bill questions, help?

A VPN uses someone else's physical network by "tunneling", wrapping packets inside packets. Usually something like a dialup service is a mix of the two. -drl
