Once the Internet became popular, it was an obvious solution to allow users in remote locations to communicate with networks over distance For example, if we had an office in New York and a user in a hotel room in Boston who wanted to access the network in New York, what better solution than to use the Internet! The problem, of course, is the security issues that surround sending data across the Internet for the entire world to tap into! Virtual private networks (VPNs) offer a solution The idea of a VPN is that the user in Boston that is in the hotel will dial up to the Internet using the ISP in Boston provided by the hotel Once the user in the hotel has the Internet connection, he or she will then dial the IP address of the VPN server in New York to create a secure tunnel between the client system and the VPN server in New York Any data that travels between the two systems will be encrypted and therefore will be considered secure Two of the major benefits of VPN are secured communication across an unsecured medium Both PPTP and L2TP are and the lack of long-distance costs incurred to VPN protocols used to create a secure communicate between the two locations Once tunnel across an unsecured network such all systems have an Internet connection, VPN as the Internet solutions leverage that Internet connection and add security to it

Just as there are two primary RAS protocols (SLIP and PPP), there are two primary VPN protocols that provide this tunneling security; they are the Point-toPoint Tunneling Protocol (PPTP) and the Layer 2 Tunneling Protocol (L2TP)

The Point-to-Point Tunneling Protocol (PPTP) is a network protocol that provides for the secure transfer of data from a remote client to a private server by creating a multiprotocol virtual private network, or VPN PPTP is used in TCP/IP networks as an alternative to conventional dial-up networking methods This system enables multiprotocol secure communication over a public TCP/IP network such as the Internet PPTP takes advantage of an additional level of security that is not currently available in other standard implementations PPTP is actually an extension of PPP It encapsulates PPP packets into IP datagrams for transmission across a network This system enables the functionality of PPP while taking advantage of the security features offered by the VPN technology Using both options tied into one protocol, you get the best of both worlds

PPTP became recognized by the IETF (a standards committee) in June 1996 Although many tunneling protocols have been created and implemented, this was the first standard tunneling protocol to become available Many vendors have adopted it in an attempt to provide a secure method to connect across the public Internet into a corporate internal network

VPNs are used to provide tunneling through a public network with a secure communications channel Users can employ PPTP to dial into a public network, such as PSTN, to use the Internet to connect to their corporate offices This system enables users to use the network infrastructure that is already in place; it eliminates the need for dedicated modem banks for users PPTP tunneling can be defined as the process of routing packets through an intermediate public network to reach a private network Only the PPTP-enabled client can access the remote network; other clients on the same segment cannot The interesting thing about this process is that you can dial into a standard PPP server and use it to establish a PPTP connection to the remote network No
Virtual Private Networks (VPNs)
additional setup or option choices are required of your ISP; most offer PPP access already You could also set up a PPTP server to dial into; this setup would enable you to only require PPP to be set up on the clients Once the PPTP server receives the packet from the client connection, it routes the data to the appropriate resource This occurs by stripping off the PPTP and PPP overhead to obtain the addressing information originally applied to it The PPTP server must be configured with TCP/IP to communicate with PPTP and whatever other protocols are being passed through this VPN tunnel A VPN works by encapsulating the data within IP packets to transport it through PPP This enables the data to pass through the Internet and use the standards already in place No configuration changes are required to your existing network stacks; they can be used as-is over the PPTP connection Other protocols, such as NetBEUI and IPX, can also pass through this secure connection VPNs are virtual devices set up as though they were regular devices such as modems In addition, PPTP must be set up on the client and the server Host computers in the route between these two computers do not need to be PPTP aware, since the packet s IP header is not encrypted They need only provide an IP route to the remote server Figure 8-10 shows the layout of a VPN solution
