A virtual private network (VPN)
– LAN to LAN over Internet connection.
• This is creating a end-to-end LAN connection over Internet
– A VPN is a private network that uses a public network (usually the
Internet) to connect remote sites or users together.
– Instead of using a dedicated, real-world connection, such as leased
line, a VPN uses "virtual" connections routed through the Internet
from the company's private network to the remote site or employee.
• For example, a user may use a VPN to connect to their work
computer terminal from home and access their email, files,
images, etc.
