Using the LAN IP Setup Options

The LAN IP Setup menu allows configuration of LAN IP services such as Dynamic Host

Configuration Protocol (DHCP) and Routing Information Protocol (RIP).

To configure LAN IP Settings:

From the main menu of the browser interface, under Advanced, click LAN IP Setup to view the

LAN IP Setup menu:

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 menu.

The LAN IP parameters 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 Out Only, the router broadcasts its routing table periodically.

–

When set to Both or In Only, the router incorporates the RIP information that it receives.

–

When set to None, the router does not send any RIP packets and ignores any RIP

packets received.

•

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 RIP-1.

–

RIP-1 is universally supported. RIP-1 is usually adequate unless you have an unusual

network setup.

–

RIP-2 carries more information. RIP-2B uses subnet broadcasting.

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 menu. 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. See

“Internet Networking and TCP/IP Addressing” in Appendix B

for an explanation of DHCP and

information about how to assign IP addresses for your network.

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 may 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 menu;

otherwise, the router’s LAN IP address)

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.

•

Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menu)

To use another device on your network as the DHCP server, or to manually configure the network

settings of all of your computers, deselect Use Router as DHCP Server. Otherwise, leave it

selected. If you deselect this service and no other DHCP server is available on your network, you

will 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 will always

receive 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 box, 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.

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.

Tip:

If the computer is already present on your network, you can copy its MAC

address from the Attached Devices menu 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.
