Field Name

Description

Starting Local Address

Displays the starting address used by the built-in DHCP server

to distribute Private LAN IP addresses. In the example shown,

addresses between 2 and 9 can be used for devices on your

Private LAN that require fixed IP addresses such as printers or

a device assigned as a DMZ host.

Note:

The LAN IP address ending in 1 is reserved for the

internal gateway server. The LAN IP address ending in 255 is

also reserved and should not be used for CPE devices.

Number of CPEs

Enter the maximum number of devices allowed to connect to

the Private LAN.

Notes:



The Factory Default is 245. The maximum number of

devices is 253. This is the combined total of addresses

reserved for static IP addresses, for example, the sum of the

IP addresses between 2 and the value entered in the Starting

Local Address field and the value entered in the Number of

CPEs field.



The sum of the value entered in the Starting Local Address

field and the value entered in the Number of CPEs field

must always be 255 or less.

DHCP Client Lease Info

Displays the MAC address, IP Address, Subnet Mask, Duration

and Expiration date of all devices issued an IP address by the

built-in DHCP server. This field also displays the current

system time and date.

Reserving IP Addresses

Use the Setup Basic Settings - Fixed CPE IP Assignment page to reserve IP

addresses. This feature allows you to assign a fixed IP address to any device in your

network by setting static IP addresses in your PC or other network device.

These addresses will be removed from the pool of the IP addresses to be used by

your gateway's DHCP server when issuing IP addresses to devices that are

connected to your local network.

Reserving IP addresses is useful in making sure that there are no IP address conflicts

on the network, for example, two devices using the same IP address. Another

example: when using DMZ Host, the IP address for the DMZ Host should always

have the same IP address.

Note:

If you are not familiar with the Fixed CPE IP Assignment procedures detailed

in this section, contact your service provider before you attempt to change any of the

residential gateway default Fixed CPE IP Assignment settings.

Click

Fixed CPE IP Assignment
