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’s The protocol used by the network that the information is traveling over.
- Encapsulating protocol â€“ The protocol (GRE, IPSec, L2F, PPTP, L2TP) that is wrapped around the original data
- Passenger protocol â€“ 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. What Next â€¦
