Blocking Access to Internet Services
The Wireless-G Router allows you to block the use of certain Internet services by computers on 
your network. This is called service blocking or port filtering. 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 block access to Internet services:
1.Select Block Services under Content Filtering in the main menu. The Block Services screen 
displays.
2.Enable service blocking by selecting either Per Schedule or Always, and then click Apply. 
To block by schedule, be sure to specify a time period in the Schedule screen. For information 
about scheduling, see “Scheduling Blocking” on page 3-5.

3.Specify a service for blocking by clicking Add. The Block Services Setup screen displays.
4.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.
5.Select the radio button for the IP address configuration you want to block, and then enter the 
IP addresses in the appropriate fields.
6.Click Add to enable your Block Services Setup selections.
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 port 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. You can often determine port number information by contacting the publisher of 
the application, by asking user groups or newsgroups, or by searching.
• Enter the starting port and ending port numbers. If the application uses a single port number, 
enter that number in both fields.
• If you know that the application uses either TCP or UDP, select the appropriate protocol. If 
you are not sure, select Both.

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 might fill up. In this case, the router overwrites the log and discards its contents.
5.Click Apply to save your settings.
So that the log entries are correctly time-stamped and sent at the correct time, be sure to set the 
time as described in the next section.
Setting the Time
The Wireless-G Router uses the Network Time Protocol (NTP) to obtain the current time and date 
from one of several network time servers on the Internet. To localize the time for your log entries, 
you must specify your time zone:
•Time Zone. Select your local time zone. This setting is used for the blocking schedule and for 
time-stamping log entries.
•Automatically Adjust for Daylight Savings Time. Select this check box if your region 
supports daylight savings time. The router will automatically adjust the time at the start and 
end of the daylight savings time period.

Configuring a Device Name
The device name is a user-friendly name for the router. This name is shown in the Network on 
Windows Vista and the Network Explorer on all Windows systems. The Device Name field cannot 
be blank. The default name is WNR3500.
Configuring LAN TCP/IP Setup Parameters
The router is shipped preconfigured to use private IP addresses on the LAN side and to act as a 
DHCP server. 
The router’s default LAN IP configuration is:
• LAN IP address. 192.168.1.1
• Subnet mask. 255.255.255.0
These addresses are part of the designated private address range for use in private networks and 
should be suitable for most applications. If your network has a requirement to use a different IP 
addressing scheme, you can make those changes in this screen.
The LAN IP settings are:
•IP Address. The LAN IP address of the router.
•IP Subnet Mask. The LAN subnet mask of the router. Combined with the IP address, the IP 
subnet mask allows a device to know which other addresses are local to it, and which must be 
reached through a gateway or router.
Using the Router as a DHCP Server
By default, the router functions as a DHCP server, allowing it to assign IP, DNS server, and default 
gateway addresses to all computers connected to the router’s LAN. The assigned default gateway 
address is the LAN address of the router. The router assigns IP addresses to the attached computers 
from a pool of addresses specified in this screen. Each pool address is tested before it is assigned to 
avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. Click 
the link to the online document “TCP/IP Networking Basics” in Appendix B for an explanation of 
DHCP and information about how to assign IP addresses for your network. 
Note: If you change the LAN IP address of the router while connected through the 
browser, you will be disconnected. You must then open a new connection to the 
new IP address and log in again.

Customizing Your Network Settings 4-3
v1.1, May 2008
Specify the pool of IP addresses to be assigned by setting the starting IP address and ending IP 
address. These addresses should be part of the same IP address subnet as the router’s LAN IP 
address. Using the default addressing scheme, you should define a range between 192.168.1.2 and 
192.168.1.254, although you might wish to save part of the range for devices with fixed addresses.
The router delivers the following parameters to any LAN device that requests DHCP:
• An IP address from the range you have defined
• Subnet mask
• Gateway IP address (the router’s LAN IP address)
• Primary DNS server (if you entered a primary DNS address in the Basic Settings screen; 
otherwise, the router’s LAN IP address)
• Secondary DNS server (if you entered a secondary DNS address in the Basic Settings screen)
To use another device on your network as the DHCP server, or to manually specify the network 
settings of all of your computers, clear the Use Router as DHCP Server check box. Otherwise, 
leave it selected. If this service is not selected and no other DHCP server is available on your 
network, you need to set your computers’ IP addresses manually or they will not be able to access 
the router.
Using Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer always 
receives the same IP address each time it accesses the router’s DHCP server. Reserved IP 
addresses should be assigned to computers or servers that require permanent IP settings. 
To reserve an IP address: 
1.Click Add. 
2.In the IP Address field, type the IP address to assign to the computer or server. (Choose an IP 
address from the router’s LAN subnet, such as 192.168.1.x.) 
3.Type the MAC address of the computer or server.
Tip: If the computer is already present on your network, you can copy its MAC 
address from the Attached Devices screen and paste it here.

4.Click Apply to enter the reserved address into the table. 
To edit or delete a reserved address entry: 
1.Click the button next to the reserved address you want to edit or delete. 
2.Click Edit or Delete.
Using a Dynamic DNS Service
If your Internet Service Provider (ISP) gave you a permanently assigned IP address, you can 
register a domain name and have that name linked with your IP address by public Domain Name 
Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you do 
not know in advance what your IP address will be, and the address can change frequently. In this 
case, you can use a commercial Dynamic DNS service, which allows you to register your domain 
to their IP address, and forwards traffic directed at your domain to your frequently changing IP 
address.
Your router contains a client that can connect to the Dynamic DNS service provided by 
DynDNS.org. You must first visit their website at www.dyndns.org and obtain an account and host 
name, which you specify in the router. Then, whenever your ISP-assigned IP address changes, 
your router automatically contacts the Dynamic DNS service provider, logs in to your account, and 
registers your new IP address. If your host name is hostname, for example, you can reach your 
router at hostname.dyndns.org.
Note: The reserved address is not assigned until the next time the computer contacts 
the router’s DHCP server. Reboot the computer or access its IP configuration 
and force a DHCP release and renew.
Note: If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the 
Dynamic DNS service will not work because private addresses are not routed on 
the Internet.
