Configuring the LAN

(Local Area Network)

The settings on this page allow you to configure the wired

network settings. Devices connected to the router’s Ethernet

ports comprise its LAN. The router’s IP is defined in the

IP

Address

field. The default setting of the DHCP server is set

to

Enabled

so that networked clients (computers, home

entertainment components, printers, etc.) will automatically be

assigned IP addresses by the router.

More advanced users may wish to configure the DNS server

settings to meet their specific requirements. Changing the

settings in this section are not necessary for most situations.

To view the LAN settings, click

System,

then click

LAN

.

Note:

Keep the router’s default values if you are uncertain of

the settings values.

802.1d Spanning Tree

Spanning Tree is disabled by default. When enabled, Spanning

Tree prevents network loops (transmissions won’t pass the

same node twice or several times to reach the destination).

Note:

The default device IP address is 192.168.0.1.

43

DHCP Server

The DHCP server assigns IP addresses to the devices on the LAN.

DHCP Server

Enable or disable the DHCP server (Default: Enabled).

Lease Time

Configure the amount of time each allocated IP address can be

used by a client.

Start IP

The first IP address in the range of addresses assigned by the

router.

End IP

The last IP address in the range of addresses assigned by the

router.

Domain Name

The domain name of the router.

in the table.

MAC Address

Displays the MAC address of the static DHCP client device

in the table.

Expiration Time

The date and time when the current DHCP address

is no longer valid.

Enable Static DHCP IP

There are reasons why you may want to enable a static IP

address on a client device on your ESR router’s network.

On occasion, if there are power outages or if you’ve reconfigured

the settings on your ESR router and reboot (restart) it to apply

the new settings, the previous IP address that the router’s DHCP

server assigned to one or more devices on the network may have

changed. Some client devices on your network may also have

web configuration interfaces (set top boxes, Network Attached

Storage, etc.) that are accessible from the router’s assigned

IP address from its DHCP server, so the client device can be

managed. Thus if the client device’s IP address changes from

time to time, it may be difficult linking to it unless you find its

new address through the ESR router’s DHCP Client Table.

If you wish to avoid this, then the Enable Static DHCP IP option

allows you set a static (essentially a permanent) address for

given client devices on your network.

To do so, select the

Enable Static DHCP IP

option.

IP Address

Enter the IP address of the device to add as a static DHCP client.

MAC Address

Enter the MAC address of the device to add as a static DHCP

client.

Click

Add

to add the device to the static DHCP client table or

Reset

to return the table to its previous state.
