Block Services (Port Filtering)
Services are functions performed by server com
puters 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 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 number 80 is an HTTP 
(web server) request. 
The service numbers for many common protoc ols are defin
 ed by the Internet Engineering 
Task Force (IETF at  http://www.ietf.org/) and published in RFC1700, “Assigned Numbers.” 
Service numbers for other applications are typi cally chosen from the range 1024 to 65535 by 
the authors of the application. Although the rout er 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 user groups or 
newsgroups, or by searching.
The Block Services screen lets you add and block specific Interne t services by co
 mputers on 
your network. This is called service blocking or  port filtering. To add a service for blocking, 
first determine which port number or range of numbers are used by the application. 
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 described in 
Schedule Blocking  on pag
 e 67.

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 choices. To add any 
additional services or applications that do not already appear, select  User Defined.
5. If you know that the application uses either  T
 CP or UDP, select the appropriate protocol. If 
you are not sure, select  Both.
6. Enter th e 
 starting and ending port numbers. If the application uses a single port number, 
enter that number in both fields.
7. Select the rad i
 o button for the IP address configuration you want to block, 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.

configuration screen of your email program. If you leave this field blank, 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 Email Address 
fie
 ld. 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.

au
 thentication  check box. Fill in the User Name and  Password fields for the outgoing email 
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 t he 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 discards its contents.
7. Click  Apply  to save your settings.

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 NETGEAR genie screens when new firm ware is available for your product.
You can use the Check button on the Router Update screen to check and update to the latest 
firmware for your p roduct if n

ew firmware is available. 
To check for new firmware and update your router:
1.Select  Advance d > Ad
 ministration > Router Update  to display the following screen: 
Click 
Check
2.Click  Check .
The router finds new firmware information if any is available.
3. Click  Yes to update
  and locate the firmware you downloaded (the file ends in .img). 
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 releas e notes to determine whether or not you 
need to reconfigure the router after upgrading.
