Block Services (Port Filtering)
Services are functions performed by server computers at the request of c\
lient computers. For 
example, web servers serve web pages, time servers serve time and date i\
nformation, and 
game hosts serve data about other players’ moves. When a computer on \
the Internet sends 
a request for service to a server computer, 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 the destination port nu\
mber 80 is an HTTP 
(web server) request. 
The service numbers for many common protocols are defined by the Interne\
t Engineering 
T
 ask Force (IETF at http://www.ietf.org/ ) and published in RFC1700, “Assigned Numbers.” 
Service numbers for other applications are typically chosen from the ran\
ge 1024 to 65535 by 
the authors of the application. 
 Although the router already holds a list of many service port 
numbers, you are not limited to these choices. You can often determine port number 
information by contacting the publisher of the application, by asking us\
er groups or 
newsgroups, or by searching.
The Block Services screen lets you add and block specific Internet servi\
ces by computers on 
your network. 
 This is called service blocking or port filtering. To add a service to block, first 
determine which port number or range of numbers are used by the applicat\
ion. 
To block services:
1.  Select 
Advanced > Security > Block Services  to display the following screen:
2. Select either Per Schedule or  Always to enable service blocking, and click  Apply. If you 
selected Per Schedule, specify a time period in the Schedule screen as d\
escribed in 
Schedule Blocking  on page  62.

3. 
Click  Add to add a service. The Block Services Setup screen displays:
4. From the Service Type list, select the application or service to allow or block. The list already 
displays several common services, but you are not limited to these choic\
es. To add any 
services or applications that do not already appear, select  User Defined.
5.  If you know that the application uses either 
 TCP or UDP, select the appropriate protocol. If 
you are not sure, select Both.
6.  Enter the starting and ending port numbers. If the application uses a si\
ngle port number
 , 
enter that number in both fields.
7.   Select the radio button for the IP address configuration you want to bl\
ock and enter the IP 
addresses. 

You can block the specified service for a single computer, a range of computers 
with consecutive IP addresses, or all computers on your network.
8.  Click  Add to enable your Block Services Setup selections.
Schedule Blocking
You can specify the days and time that you want to block Internet access.\

elect the 
Automatically adjust for daylight savings time  check box.

To set up email notifications:
1. 
Select  Advanced > Security >  E-mail to display the following screen:
2. To receive email logs and alerts from the  router, select the Turn E-mail Notification On  
check box.
3.  In the 
Your Outgoing Mail Server field, enter the name of your ISP’s outgoing (SMTP) mail 
server (such as mail.myISP.com). You might be able to find this information in the 
configuration screen of your email program. If you leave this field blan\
k, log and alert 
messages are not sent by email.
4.  Enter the email address to which logs and alerts are sent in the Send to\
 
 This E-mail Address 
field. This email address is also used for the From address. If you leave this \
field blank, log 
and alert messages are not sent by email.
5.  If your outgoing email server requires authentication, select the  My Mail Server requires 
authentication  check box. Fill in the User Name and Password fields for the outgoing e\
mail 
server

.
6.   
You can have email alerts sent immediately when someone attempts to visit\
 a blocked site 
and you can specify that logs are sent automatically.
If you select the Weekly, Daily, or Hourly option and the log fills up before the specified 
period, the log is automatically emailed to the specified email address.\
 
 After the log is 
sent, the log is cleared from the router’s memory. If the router cannot email the log file, the 
log buffer might fill up. In this case, the router overwrites the log and disca\
rds its contents.

Upgrade the Router Firmware
The router firmware (routing software) is stored in flash memory. You can update the 
firmware from the Administration menu on the Advanced tab. You might see a message at 
the top of the genie screens when new firmware is available for your pro\
duct.
You can use the Check button on the Router Upgrade screen to check and up\
date to the  latest firmware for your product if new firmware is available. 
To check for new firmware and update your router:
1.  Select  Advanced > 
 Administration > Router Update  to display the following screen: 
Click 
Check
2. Click  Check .
The router finds new firmware if any is available.
3.  Click  Ye
 s to update and locate the firmware you downloaded (the file ends in .im\
g). 
WARNING:
When uploading firmware to the router, do not  interrupt the web 
browser by closing the window, clicking a link, or loading a new 
page. If the browser is interrupted, it could corrupt the firmware.
When the upload is complete, your router restarts. The upgrade process typically takes 
about 1 minute. Read the new firmware release notes to determine whether\
 you need to 
reconfigure the router after upgrading.
