Content Filtering
This chapter describes how to use the content filtering features of the 108 Mbps Wireless Firewall 
Router WGT624 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 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 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:
Figure 5-1:  Block Sites menu
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  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 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:
Figure 5-2:  Block Services menu

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

the application. This information can usually be determined by contacting the publisher of the 
application or from user groups of newsgroups.
Enter the Starting Port and Ending Port numbers. If the application uses a single port number, enter 
that number in both boxes.
If you know that the application uses either TCP or UDP, select the appropriate protocol. If you are 
not sure, select Both.
• Configuring Services Blocking by IP Address Range
Under “Filter Services For”, you can block the specified service for a single PC, a range of PCs 
(having consecutive IP addresses), or all PCs on your network.
Scheduling When Blocking Will Be Enforced
The WGT624 wireless router allows you to specify when blocking will be enforced. The Schedule 
menu is shown below:

Viewing Logs of Web Access or Attempted Web Access
The log is a detailed record of what websites you have accessed or attempted to access. Up to 128 
entries are stored in the log. Log entries will only appear when keyword blocking is enabled, and 
no log entries will be made for the Trusted User. An example is shown below:

• Send to this e-mail address  
Enter the e-mail address to which logs and alerts are sent. This e-mail address will also be used 
as the From address. If you leave this box blank, log and alert messages will not be sent via 
e-mail. 
You can specify that logs are automatically sent to the specified e-mail address with these options:
• Send alert immediately 
Check this box if you would like immediate notification of attempted access to a blocked site.
• Send logs according to this schedule 
Specifies how often to send the logs: None, Hourly, Daily, Weekly, or When Full. 
– Day for sending log. Specifies which day of the week to send the log. Relevant when the 
log is sent weekly or daily.
– Time for sending log. Specifies the time of day to send the log. Relevant when the log is 
sent daily or weekly.
If the Weekly, Daily or Hourly option is selected and the log fills up before the specified 
period, the log is automatically e-mailed to the specified e-mail address. After the log is sent, 
the log is cleared from the router’s memory. If the router cannot e-mail the log file, the log 
buffer may fill up. In this case, the router overwrites the log and discards its contents. If you 
dont want logs sent, select None from the list in the Send Logs According To This Schedule 
area. When you turn on e-mail notification and choose None in the Send Logs According to 
this Schedule list, the alert is sent but not the log.
The WGT624 wireless router uses the Network Time Protocol (NTP) to obtain the current time and 
date from one of several Network Time Servers on the Internet. In order to localize the time for 
your log entries, you must specify your Time Zone:
• Time Zone. Select your local time zone. This setting will be used for the blocking schedule 
and for time-stamping log entries.
• Daylight Savings Time. Check this box if your time zone is currently under daylight savings 
time.
Note: If your region uses Daylight Savings Time, you must manually select Adjust for 
Daylight Savings Time on the first day of Daylight Savings Time, and unselect it at the 
end. Enabling Daylight Savings Time will cause one hour to be added to the standard time.
