Tunneling

Most VPNs rely on tunneling to create a private network that reaches across the Internet. Essentially,

tunneling is the process of placing an entire packet within another packet and sending it over a

network. The protocol of the outer packet is understood by the network and both points, called tunnel

interfaces, where the packet enters and exits the network.

Tunneling requires three different protocols:

• Carrier protocol – The protocol used by the network that the information is traveling over

• Encapsulating protocol – The protocol (GRE, IPSec, L2F, PPTP, L2TP) that is wrapped

around the original data

• Passenger protocol – The original data (IPX, NetBEUI, IP) being carried

Tunneling has amazing implications for VPNs. For example, you can place a packet that uses a

protocol not supported on the Internet (such as NetBEUI) inside an IP packet and send it safely over

the Internet. Or you could put a packet that uses a private (non-routable) IP address inside a packet

that uses a globally unique IP address to extend a private network over the Internet.
