Creating a virtual private network

A virtual private network (VPN) is an interconnection between two networks that uses the PPTP (point-to-point tunneling protocol). By using the Internet to transport data, a VPN can eliminate long distance charges associated with traditional dial-up solutions. And, since PPTP provides a secure connection, network security is not compromised.
