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 (or URL-filtering) you can

block web sites based on their address

(for example

www.porn.com).

Content-based filtering

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 the list of addresses up-to-date.

To solve this problem Thomson Gateway introduced content-based filtering.

With content-based filtering you can

block web sites based on their content category

(for example

pornography) instead of their URL. This way, you only need to select the appropriate categories 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, you can still access a specific address provided you create a rule to allow access to that

URL.

For example, if you are blocking content from the

Finance / Investment

category, you can create a rule to

make an exception for netbanking.mybank.com.

category and allow access to netbanking.mybank.com,

netbanking.mybank.com will still be accessible.
