Event Log

The Event Log page shows you the events related to the settings of Parental Control.

This table is a running list of the last 30 Parental Control access violations that include

the following items on Internet traffic:

•

If the user's internet access is blocked. (time filter)

•

If a blocked keyword is detected in the URL.

•

If a blocked domain is detected in the URL.

•

If the online lookup service detects that the URL falls in a category that is

blocked.

VPN (Virtual Private Network) Menu Options

The VPN Menu lets you:

•

Configure a VPN tunnel

•

View VPN event logs

Basic Setting

This page allows you to enable VPN protocols and manage VPN tunnels. A virtual

private network (VPN) is a computer network in which some of the links between nodes

are carried by open connections or virtual circuits within some larger network (e.g., the

Internet) as opposed to by physical wires, as in a traditional private network. A VPN can

be used to separate the traffic of different user communities over an underlying network

with strong security features.

To access the

Basic

page:

1

Click the

menu tab.

Then click the

IPSec

The IPSec page allows you to configure IPSec tunnel and endpoint settings. A VPN

tunnel is usually established in two phases. Each phase establishes a security

association (SA), a contract indicating what security parameters Cable Modem/Router

and the remote IPSec Cable Modem/Router will use.

•

The

first phase

establishes an Internet Key Exchange (IKE) SA between the

Cable Modem/Router and the remote IPSec Cable Modem/Router.

•

The

second phase

uses the IKE SA to securely establish an IPSec SA through

which the Cable Modem/Router and remote IPSec Cable Modem/Router can

send data between computers on the local network and remote network.

Before IPSec VPN configuration, try to familiarize yourself with terms like IPSec

Algorithms, Authentication Header and ESP protocol.

IPSec Algorithms

The ESP and AH protocols are necessary to create a Security Association (SA), the

foundation of an IPSec VPN. An SA is built from the authentication provided by the AH

and ESP protocols. The primary function of key management is to establish and maintain

the SA between systems. Once the SA is established, the transport of data may

commence.

AH (Authentication Header) Protocol

The AH protocol (RFC 2402) was designed for integrity, authentication, sequence

integrity (replay resistance), and non-repudiation but not for confidentiality, for which the

ESP was designed.

In applications where confidentiality is not required or not sanctioned by government

encryption restrictions, an AH can be employed to ensure integrity. This type of

implementation does not protect the information from dissemination but will allow for

verification of the integrity of the information and authentication of the originator.

ESP (Encapsulating Security Payload) Protocol

The ESP protocol (RFC 2406) provides encryption as well as the services offered by AH.

ESP authenticating properties are limited compared to the AH due to the non-inclusion of

the IP header information during the authentication process. However, ESP is sufficient if

only the upper layer protocols need to be authenticated. An added feature of the ESP is

payload padding, which further protects communications by concealing the size of the

packet being transmitted.
