Question from xactlywhatisaid
"Whats a virtual private network and when would you need to use one?"

Answer from Krapitino
"In oversimplified terms, its an encryption "tunnel" through the internet to create a secure connection from LAN "A" to LAN "B"

When would you use it? When youre a corporation trying to get your work-at-home folks the same connectivity as in the office over a standard broadband connection (like cable or DSL) and still have the security of having them A) plugged in behind the firewall or B) dialing up to a private phone number"
