Content Filtering

This chapter describes how to use the content filtering features of the 108 Mbps Wireless Firewall

Router WGT624 v2 to protect your network. These features can be found by clicking on the

Content Filtering heading in the Main Menu of the browser interface.

The 108 Mbps Wireless Firewall Router WGT624 v2 provides you with web content filtering

options, plus browsing activity reporting and instant alerts via e-mail. Parents and network

administrators can establish restricted access policies based on time-of-day, web addresses and

web address keywords. You can also block Internet access by applications and services, such as

chat or games.

Blocking Access to Internet Sites

The WGT624 v2 wireless router allows you to restrict access based on web addresses and web

address keywords. Up to 255 entries are supported in the Keyword list. The Block Sites menu is

below:

To enable keyword blocking, select either “Per Schedule” or “Always”, then click Apply. If you

want to block by schedule, be sure that a time period is specified in the Schedule menu.

To add a keyword or domain, type it in the Keyword box, click Add Keyword, then click Apply.

To delete a keyword or domain, select it from the list, click Delete Keyword, then click Apply.

Keyword application examples:

•

If the keyword "XXX" is specified, the URL <http://www.badstuff.com/xxx.html> is blocked.

•

If the keyword “.com” is specified, only websites with other domain suffixes (such as .edu or

.gov) can be viewed.

•

If you wish to block all Internet browsing access during a scheduled period, enter the keyword

“.” and set the schedule in the Schedule menu.

To specify a Trusted User, enter that PC’s IP address in the Trusted User box and click Apply. You

may specify one Trusted User, which is a PC that will be exempt from blocking and logging. Since

the Trusted User will be identified by an IP address, you should configure that PC with a fixed IP

address.

Blocking Access to Internet Services

The WGT624 v2 wireless router allows you to block the use of certain Internet services by PCs on

your network. This is called services blocking or port filtering. The Block Services menu is shown

below:

Services are functions performed by server computers at the request of client computers. For

example, web servers serve web pages, time servers serve time and date information, and game

hosts serve data about other players’ moves. When a computer on your network sends a request for

service to a server computer on the Internet, the requested service is identified by a service or port

number. This number appears as the destination port number in the transmitted IP packets. For

example, a packet that is sent with destination port number 80 is an HTTP (web server) request.

To enable service blocking, select either Per Schedule or Always, then click Apply. If you want to

block by schedule, be sure that a time period is specified in the Schedule menu.

To specify a service for blocking, click Add. The Add Services menu will appear, as shown below:

Figure 5-3:

Add Services menu

From the Service Type list, select the application or service to be allowed or blocked. The list

already displays several common services, but you are not limited to these choices. To add any

additional services or applications that do not already appear, select User Defined.

•

Configuring a User Defined Service

To define a service, first you must determine which port number or range of numbers is used by

the application. The service numbers for many common protocols are defined by the Internet

Engineering Task Force (IETF) and published in RFC1700, “Assigned Numbers.” Service

numbers for other applications are typically chosen from the range 1024 to 65535 by the authors of
