Use the LAN Setup Options

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

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

The N300 wireless modem router is shipped preconfigured to use private IP addresses on the LAN side and to act as a DHCP server. The N300 wireless modem router’s default LAN

IP configuration is:

• LAN IP address. 192.168.0.1

• 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 the LAN Setup screen.

 To configure LAN settings:

1. Log in to the N300 wireless modem router, and from the main menu, select Advanced

> LAN Setup. The following screen displays:

2. After you make changes, you need to click Apply for the changes to take effect.

Note: If you change the LAN IP address of the N300 wireless modem router while connected through the browser, you will be disconnected. You need to then open a new connection to the new

IP address and log in again.

The LAN Setup fields are explained in the following table.

Description

The LAN IP address of the N300 wireless modem router.

The LAN subnet mask of the N300 wireless modem router.

Combined with the IP address, the IP subnet mask allows a device to know which other addresses are local to it, and which needs to be reached through a gateway or N300 wireless modem router.

RIP (Router Information Protocol) allows the N300 wireless modem router to exchange routing information with other routers. This setting controls how the N300 wireless modem router sends and receives RIP packets. Both is the default.

• Both or Out Only. The N300 wireless modem router broadcasts its routing table periodically.

• Both or In Only. The N300 wireless modem router incorporates the RIP information that it receives.

• None. The N300 wireless modem router will not send any

RIP packets and will ignore any RIP packets received.

DHCP Server

RIP Version

Use Router as a DHCP

Server

This controls the format and the broadcasting method of the

RIP packets that the N300 wireless modem router sends. It recognizes both formats when receiving. By default, this is

RIP-1.

• RIP-1 is universally supported. It is adequate for most networks, unless you have an unusual network setup.

• RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 format. RIP-2B uses subnet broadcasting. RIP-2M uses multicasting.

This check box is usually selected so that the N300 wireless modem router functions as a Dynamic Host Configuration

Protocol (DHCP) server. See Use the N300 Wireless Modem

Router as a DHCP Server on page 112.

Starting IP Address

Ending IP Address

Specify the start of the range for the pool of IP addresses in the same subnet as the N300 wireless modem router.

Specify the end of the range for the pool of IP addresses in the same subnet as the N300 wireless modem router.

Address Reservation

For more information, see

Address Reservation on page 113.

When you specify a reserved IP address for a computer on the LAN, that computer receives the same IP address each time it accesses the N300 wireless modem router’s DHCP server. Assign reserved IP addresses to servers that require permanent IP settings.

Use the N300 Wireless Modem Router as a DHCP Server

By default, the N300 wireless modem router functions as a DHCP server, allowing it to assign

IP, DNS server, and default gateway addresses to all computers connected to the N300 wireless modem router’s LAN. The assigned default gateway address is the LAN address of the N300 wireless modem router. The N300 wireless modem router assigns IP addresses to

Advanced Settings (Part 1)

112

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 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 N300 wireless modem router are satisfactory.

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 N300 wireless modem router’s LAN IP address. Using the default addressing scheme, you should define a range between 192.168.0.2 and 192.168.0.254, although you might wish to save part of the range for devices with fixed addresses.

The N300 wireless modem 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 N300 wireless modem router’s LAN IP address)

• Primary DNS Server (if you entered a primary DNS address in the Basic Settings screen; otherwise, the N300 wireless modem 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 configure 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 will need to set your computers’ IP addresses manually or they will not be able to access the N300 wireless modem router.

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 N300 wireless modem 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 N300 wireless modem router’s LAN subnet, such as 192.168.0.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.
