Using LAN IP Setup Options

The LAN IP Setup feature is under the Advanced heading of the main menu. This feature allows

configuration of LAN IP services such as DHCP and RIP. From the Main Menu of the browser

interface, under Advanced, click on LAN IP Setup to view the LAN IP Setup menu, shown below.

Figure 6-5:

LAN IP Setup Menu

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 IETF-designated private address range for use in private networks,

and should be suitable in 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

This is the LAN IP address of the router.

•

IP Subnet Mask

This is 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 (Router Information Protocol) allows a router to exchange routing information with other

routers. The RIP Direction selection controls how the router sends and receives RIP packets.

None is the default.

—

When set to Both or Out Only, the router will broadcast its routing table periodically.

—

When set to Both or In Only, it will incorporate the RIP information that it receives.

—

When set to None (default), it will not send any RIP packets and will ignore any RIP

packets received.

•

RIP Version

This controls the format and the broadcasting method of the RIP packets that the router sends.

(It recognizes both formats when receiving.) By default, it is disabled.

—

RIP-1 is universally supported. RIP-1 is probably adequate for most networks, 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 will function as a DHCP (Dynamic Host Configuration Protocol) 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. IP

addresses will be assigned to the attached PCs 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

“IP

Configuration by DHCP

” on

page B-10

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 need run

ipconfig /release

and

ipconfig /renew

commands on your PC to reconnect to the router. You may need to restart your computer

for the new IP address setting to take effect.

If another device on your network will be the DHCP server, or if you will manually configure the

network settings of all of your computers, clear the ‘Use router as DHCP server’ check box.

Otherwise, leave it checked.

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

192.168.1.253, although you may wish to save part of the range for devices with fixed addresses.

The router will deliver 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)

•

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

Using Address Reservation

When you specify a reserved IP address for a PC on the LAN, that PC will always receive the

same IP address each time it access the router’s DHCP server. Reserved IP addresses should be

assigned to servers that require permanent IP settings.

To reserve an IP address:

1.

Click the Add button.

Figure 6-6:

Address Reservation screen

2.

In the IP Address box, type the IP address to assign to the PC 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 PC or server.

(Tip: If the PC is already present on your network, you can copy its MAC address from the

Attached Devices menu and paste it here.)

4.

Click Apply to enter the reserved address into the table.

Note: The reserved address will not be assigned until the next time the PC contacts the router's

DHCP server. Reboot the PC or access its IP configuration and force a DHCP release and renew.

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.

How to Configure Static Routes

Static Routes provide additional routing information to your router. Under normal circumstances,

the router has adequate routing information after it has been configured for Internet access, and

you do not need to configure additional static routes. You must configure static routes only for

unusual cases such as multiple routers or multiple IP subnets located on your network.

From the Main Menu of the browser interface, under Advanced, click on Static Routes to view the

Static Route menu, shown below.

Figure 6-7.

Static Route Summary Table

To add or edit a Static Route:

1.

Click the Add button to open the Add/Edit Menu, shown below.

2.

Type a route name for this static route in the Route Name box under the table.

(This is for identification purpose only.)
