Wired LAN Configurations

Before all computers using a wired Ethernet connection (i.e. those computers

that connect to this router’s LAN ports 1 through 4 by Ethernet cable) can

communicate with each other and access internet, they must have a valid IP

address.

There are two ways to assign IP addresses to computers: static IP address (set

the IP address for every computer manually), and dynamic IP address (IP

address of computers will be assigned by router automatically. It’s

recommended for most of computers to use dynamic IP address as it saves a

lot of time on setting IP addresses for every computer, especially when there

are a lot of computers in your network; for servers and network devices that

provide services to other computers and users that come from the Internet,

static IP address should be used so that other computers can locate the server.

Suggestions on IP address numbering plan:

If you have no idea how to define an IP address plan for your

network, here are some suggestions.

1. A valid IP address has 4 fields: a, b, c, and d; for most home

and company users, it’s suggested to use 192.168.c.d, where c

is an integer between 0 and 254, and d is an integer between 1

and 254. This router is capable to work with up to 253 clients,

so you can set ‘d’ field of the router IP address as 1 or 254 (or

any number between 1 and 254), and pick a number between 0

and 254 for field ‘c’.

2. In most cases, you should use ‘255.255.255.0’ as your subnet

mask, which allows up to 253 clients (this also utilizes the

X650’s capability of working with up to 253 clients).

3. For all servers and network devices that provide services to

other people (like Internet service, print service, and file

service), they should use static IP address. Give each of them

a unique number between 1 and 253, and maintain a list, so

that everyone can locate those servers easily.

4. For computers that are not dedicated to providing specific

services to others, they should use dynamic IP address.

If you do not understand the descriptions listed above, don’t

worry! We will provide recommended setup values below.

Please follow these instructions to set wired LAN parameters:

Please click ‘LAN’ menu on the left of the web management interface; there

are three setup groups here: ‘LAN IP’, ‘DHCP Server’, and ‘Static DHCP

Leases Table’. Here are the setup instructions for each of them:

7.1 LAN IP section:

Here are descriptions of each setup item:

IP address (1):

Please input the IP address of this router.

Subnet Mask (2):

Please input subnet mask for this network.

802.1d

If you wish to activate 802.1d spanning tree

Spanning Tree (3):

function, select ‘Enabled’ for setup item ‘802.1d

Spanning Tree’, or set it to ‘Disabled’

DHCP Server (4):

If you want to activate DHCP server function of this

router, select ‘Enabled’, or set it to ‘Disabled’.

Recommended Value if you don’t know what to place in field:

IP Address: 192.168.1.1

Subnet Mask: 255.255.255.0

802.1d Spanning Tree: Disabled

DHCP Server: Enabled

7.2 DHCP Server:

These settings are only available when ‘DHCP Server’ in ‘LAN IP’ section is

‘Enabled’; here are descriptions of each setup item:

Lease Time (1):

Please choose a lease time (the duration of time that

every computer can keep a specific IP address) of every

IP address assigned by this router from a dropdown

menu.

Start IP (2):

Please input the start IP address of the IP range.

End IP (3):

Please input the end IP address of the IP range.

Domain Name (4):

If you wish, you can also input the domain name for your

network (This is optional).

Recommended Value if you don’t know what to place in fields:

Lease Time: Two Weeks (or ‘Forever’, if you have less than 20 computers)

Start IP: 192.168.1.100

End IP: 192.168.1.200

Domain Name: (leave it blank)

NOTE:

1. The number of the last field (‘d’ field) of ‘End IP’ must be greater than

‘Start IP’, and cannot be identical to router’s IP address.

2. The former three fields of IP address of ‘Start IP’, ‘End IP’, and ‘IP

Address of ‘LAN IP’ section (‘a’, ‘b’, and ‘c’ field) should be the same.

3. These settings will affect wireless clients too.

7.3 Static DHCP Leases Table:

This function allows you to assign a static IP address to a specific computer

forever, so you do not have to set the IP address for a computer and still

enjoy the benefits of using a DHCP server. A maximum of 16 static IP

addresses can be assigned here.

(If you set ‘Lease Time’ to ‘forever’ in the ‘DHCP Server’ section, you can

also assign an IP address to a specific computer permanently; however, you

will not be able to assign a certain IP address to a specific computer since

IP addresses are be assigned in random order this way).

Here are descriptions of each setup item:

Enable Static

Check this box to enable this function,

DHCP Leases (1):

otherwise uncheck it to disable this function.

MAC Address (2):

Input the MAC address of the computer or network

device (total of 12 characters, with characters ranging

from 0 to 9, and from a to f, like ‘001122aabbcc’)

IP address (3):

Input the IP address you want to assign to this

computer or network device

‘Add’ (4):

After you inputted the MAC address and IP address

pair, click this button to add the pair to the static

DHCP leases table.

If you want to remove all of the characters you just entered, click ‘Clear’.

After you clicked ‘Add’, the MAC address and IP address mapping will be

added to the ‘Static DHCP Leases Table’ section.

If you want to delete a specific item, please check the ‘Select’ box of a

MAC address and IP address mapping (1), then click ‘Delete’ button (2); if

you want to delete all mappings, click ‘Delete All’ (3).

After you finish all LAN settings, please click ‘Apply’ button on this page.

After you click ‘Apply’, the following message will be displayed on your web

browser:

Please click ‘Continue’ to return to previous setup menu and continue router

setup, or click ‘Apply’ to reboot the router so that settings will take effect

(Please wait about 40 seconds for router to reboot).
