Customizing Your Network Settings
v1.0, June 2008
To configure LAN IP settings, select
LAN Setup
under Advanced in the main menu. The LAN
Setup screen displays.
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 WNR2000.

Configuring LAN TCP/IP Setup Parameters
These are advanced settings that you might configure if you are a network administrator and your
network contains multiple routers. The router is shipped preconfigured to use private IP addresses
on the LAN side and to act as a DHCP server (see
“Using the Router as a DHCP Server” on
page 4-4
).
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.
•
RIP Direction
. RIP allows a router to exchange routing information with other routers. The
RIP Direction selection controls how the router sends and receives RIP packets.
Both
is the
default.
–
When set to
Both
or
In Only
, the router incorporates the RIP information that it receives.
–
When set to
Both
or
Out Only
, the router broadcasts its routing table periodically.
•
RIP Version
. This controls the format and the broadcasting method of the RIP packets sent by
the router. (It recognizes both formats when receiving.) The default setting is
Disabled
.
–
RIP-1
is universally supported. RIP-1 is usually adequate unless you have an unusual
network setup.
–
RIP-2B
carries more information than RIP-1 and uses subnet broadcasting.
–
RIP-2M
carries more information than RIP-1 and uses multicasting.
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.

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.
To specify a pool of IP addresses to be assigned, set 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.
Note:
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.

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, enter 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.
Enter the MAC address of the computer or server.
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
.
Figure 4-2
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.
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.

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.
Select
Dynamic DNS
under Advanced in the main menu. The Dynamic DNS screen displays.
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.
