Chapter 8: Virtual Private Networks

8.3 VPN Basics

This section discusses basic principles and operations in Virtual Private Networks.

A VPN device encapsulates information into IP packets, and can perform as a VPN gateway over public networks that use IP. As a
VPN gateway, a VPN device can perform IPsec tunnel initiation, IPsec tunnel termination, and IPsec passthrough. Those processes
use IPsec for VPN security, performing the functions listed in Table 8-1.

The WRT4000 Series Cellular Wireless Router can implement IKEv1 or IKEv2 VPN tunnels with any other IPsec compliant VPN
gateway or VPN client. The WRT4000 Series Cellular Wireless Router supports the following tunnel modes:

• Tunnel initiation: The device receives packets from a local user terminal. The device encapsulates the packets according to the

IPsec user policy, establishes a VPN tunnel across the public network to a remote VPN gateway, and sends the packets across
the VPN tunnel toward their destination.

• Tunnel passthrough: The device receives IPsec-encapsulated packets from a client VPN terminal, and provides transparent

forwarding of the IP packets according to the IPsec user policy. The device sends the packets across the public network without
repackaging them.

• Tunnel termination: The device terminates (accepts) an IPsec tunnel initiated by a remote VPN gateway or VPN client across the

public network. The device authenticates and unpackages the tunnel’s packets, and delivers them to the destination terminal.
(To perform tunnel termination, the device must maintain a table of VPN users that function as prospective tunnel initiators; see
The IP Policy Table.)
