Web Site Filtering

Introduction

The Thomson Gateway allows you to deny access to specific web sites.

Access Denied page

When a user tries to access a page that is being blocked, the following page is displayed:

Address-based filtering

With address-based filtering you can

block web sites based on their address

, also called URL (for example

www.porn.com).

But as, you know, the Internet consists of a large number of web sites, and that number still increases every

day. This makes it almost impossible to keep this list up to date.

To solve this problem Thomson Gateway introduced content based filtering.

Content-based filtering

With content-based filtering allows you can

block web sites based on their content category

(for example

pornography) instead of the their URL. This way, you only need select the appropriate categories when you

enable this feature and the content category server takes care of the rest. This content category server is

updated at regular intervals.

Combining the two filters

Address-based filtering has priority over content-based filtering

. This means that when you are blocking a

specific category (for example

Finance / Investment

), you can still access (netbanking.mybank.com) provided

you create a rule to allow access to that URL (for example netbanking.mybank.com).

Activating content-based filtering

Before you can use content-based filtering you must first activate it by purchasing a license key at your

Internet Service Provider (ISP) or by activating the 30-day trial.

Proceed as follows:

1

Browse to the

Thomson Gateway Web Interface

.

2

On the

Toolbox

menu, click

Web Site Filtering

.

3

In the

Pick a task

list, click
