Enable NAT:

This technology translates the IP addresses of a local area network to a

different IP address for the Internet. If this Router is hosting your network’s connection to the

Internet, please select the check box. If another Router exists in your network, you don’t need

to select the option.

¾

Enable Firewall:

A firewall enhances network’s security. Select the option to use a firewall,

or else without a firewall.

¾

Enable IGMP Multicast:

This is disabled

by default. This setting will not allow IGMP (Internet

Group Management Protocol) packets to be forwarded to the LAN. IGMP is used to manage

multicasting on TCP/IP networks. Most users will not need to enable this. Some ISPs use

IGMP to perform remote configuration for client devices, such as the Router. If you are

unsure, check with your ISP.

DHCP Server:

These settings allow you to configure the Router‘s Dynamic Host

Configuration Protocol (DHCP) server function. The DHCP server is enabled by default for

the Router’s Ethernet LAN interface. DHCP service will supply IP settings to computers which

34

TD-W8910G

54M Wireless ADSL2+ Router User Guide

are configured to automatically obtain IP settings that are connected to the Router though the

Ethernet port. When the Router is set for DHCP, it becomes the default gateway for DHCP

client connected to it. Keep in mind that if you change the IP address of the Router, you must

change the range of IP addresses in the pool used for DHCP on the LAN.

±

Start IP Address:

Enter a value for the DHCP server to start with when issuing IP

addresses. Because the default IP address for the Router is 192.168.1.1, the default

Start IP Address is

192.168.1.2

, and the Start IP Address must be 192.168.1.2 or greater,

but smaller than 192.168.1.254.

±

End IP Address:

Enter a value for the DHCP server to end with when issuing IP

addresses. The End IP Address must be smaller than 192.168.1.254. The default End IP

Address is

192.168.1.254

.

±

Leased Time (hour):

The Leased Time is the amount of time in which a network user

will be allowed connection to the Router with their current dynamic IP address. Enter the

amount of time, in hours, then the user will be “leased” this dynamic IP address. After the

dynamic IP address has expired, the user will be automatically assigned a new dynamic

IP address. The default is

24

hours.

¾

Configure the second IP Address and Subnet Mask:

You can configure the Router’s

second IP Address and Subnet Mask for LAN Interface though which you can also access to

the Web-based Utility as the default IP Address and Subnet Mask.

Note:

DHCP Server and the second IP Address are not available for the connection type of

Bridge

here, they won’t display on the screen above since only Bridge is selected.
