DHCP > Setup

Setup

Enable DHCP Server

To use the Router as your network’s

DHCP server, select Enable DHCP Server. If you already

have a DHCP server on your network, remove the check

mark.

Dynamic IP

Client Lease Time

The Client Lease Time is the amount

of time a network user will be allowed connection to the

Router with their current dynamic IP address. Enter the

amount of time, in minutes, that the user will be “leased”

this dynamic IP address. The range is 5-43,200 minutes.

The default is 440 minutes.

Dynamic IP Range Start/End

Enter a starting IP address

and ending IP address to create a range of available IP

addresses. The default range is 00-49. Enter a value for

the DHCP server to start with when issuing IP addresses.

This value must be 192.168.1. 2 or greater, because the

default IP address for the Router is 192.168.1.1.

Static IP

You can assign a static IP address to a specific device based

on its MAC address.

Show unknown MAC addresses

Click Show unknown

MAC addresses to view all devices’ IP addresses and

corresponding MAC addresses. The Unknown MAC

Address List appears.

Unknown MAC Address List

To add an IP address and MAC address set to the Static

IP list, select Enable, and then click Apply. To add all IP

addresses and MAC addresses to the Static IP list, click

Select All.
To update the on-screen information, click Refresh. To

exit this screen and return to the DHCP > Setup screen,

click Close.

Static IP Address

Enter the static IP address. You can

enter 0.0.0.0 if you want the Router to assign a static IP

address to the device.

MAC Address

Enter the MAC address of the device.

Name

Enter a descriptive name for the device.

Enable

Select Enable to assign the static IP address to

this device.
Click Add to List, and configure as many entries as you

would like, up to a maximum of 100. To delete an entry,

select it and click Delete selected Entry.

Block MAC address on the list with wrong IP address

To

block traffic from devices with MAC addresses on the Static

IP list but using the wrong IP addresses, select this option.

It prevents users from changing device IP addresses

without your permission.

Block MAC address not on the list

To block traffic from

devices using dynamic IP addresses, select this option. It

blocks all devices with MAC addresses not listed on the

Static IP list.

DNS

DNS Server

You can assign DNS server(s) to the DHCP

clients so the Router will use the DNS server(s) for faster

access to functioning DNS server(s). Enter the IP address

of at least one DNS server.

WINS

WINS Server

Windows Internet Naming Service (WINS)

is a service that resolves NetBIOS names to IP addresses.

WINS is assigned if the computer (DHCP client) requests

one. If you do not know the IP address of the WINS server,

keep the default, 0.0.0.0.
