About VPNs

Overview

A VPN (Virtual Private Network) provides a secure connection between 2 points, over an
insecure network - typically the Internet. This secure connection is called a

VPN Tunnel

.

There are many standards and protocols for VPNs. The standard implemented in the
ADSL2/2+ Broadband Router is

IPSec

.

IPSec

IPSec is a near-ubiquitous VPN security standard, designed for use with TCP/IP networks. It
works at the packet level, and authenticates and encrypts all packets traveling over the VPN
Tunnel. Thus, it does not matter what applications are used on your PC. Any application can
use the VPN like any other network connection.

IPsec VPNs exchange information through logical connections called

SA

s (Security

Associations). An SA is simply a definition of the protocols, algorithms and keys used
between the two VPN devices (endpoints).

Each IPsec VPN has two SAs - one in each direction. If

IKE

(Internet Key Exchange) is used

to generate and exchange keys, there are also SA's for the IKE connection as well as the IPsec
connection.

There are two security modes possible with IPSec:

•

Transport Mode

- the payload (data) part of the packet is encapsulated through

encryption but the IP header remains in the clear (unchanged).

The ADSL2/2+ Broadband Router does NOT support Transport Mode.

•

Tunnel Mode

- everything is encapsulated, including the original IP header, and a new IP

header is generated. Only the new header in the clear (i.e. not protected). This system
provides enhanced security.

The ADSL2/2+ Broadband Router always uses Tunnel Mode.

IKE

IKE (Internet Key Exchange) is an optional, but widely used, component of IPsec. IKE
provides a method of negotiating and generating the keys and IDs required by IPSec. If using
IKE, only a single key is required to be provided during configuration. Also, IKE supports
using

Certificates

(provided by CAs - Certification Authorities) to authenticate the identify of

the remote user or gateway.

If IKE is NOT used, then all keys and IDs (SPIs) must be entered manually, and Certificates
can NOT be used. This is called a "Manual Key Exchange".

When using IKE, there are 2 phases to creating the VPN tunnel:

•

Phase I

is the negotiation and establishment up of the IKE connection.

•

Phase II

is the negotiation and establishment up of the IPsec connection.
