TD-W8901G 54Mbps Wireless ADSL2+ Modem Router User Guide

The ADSL ATU-R supports both IGMP version 1 (IGMP v1) and IGMP v2. Select

“Disabled” to disable it.

• IGMP Snoop: Enable the IGMP Snoop function if you need.

¾ DHCP Server: Select Enabled, then you will see the screen below (shown in Figure 4-12).

The Router will work as a DHCP Server; it becomes the default gateway for DHCP client

connected to it. DHCP stands for Dynamic Host Control Protocol. The DHCP Server gives out

IP addresses when a device is booting up and request an IP address to be logged on to the

network. That device must be set as a DHCP client to obtain the IP address automatically. By

default, the DHCP Server is enabled. The DHCP address pool contains the range of the IP

address that will automatically be assigned to the clients on the network.

• Starting IP Address: Enter the starting IP address for the DHCP server's IP assignment.

Because the default IP address for the Router is 192.168.1.1, the default Start IP

Address is 192.168.1.100, and the Start IP Address must be 192.168.1.100 or greater,

but smaller than 192.168.1.254.

• IP Pool Count: The max user pool size.

• Lease Time: The length of time for the IP lease. After the dynamic IP address has

expired, the user will be automatically assigned a new dynamic IP address. The default is

259200 seconds.

• Physical Ports: Specify the Physical Ports of the DHCP client.

• DNS Relay: If you want to disable this feature, you just need to set both Primary and

secondary DNS IP to 0.0.0.0. If you want to use DNS relay, you can setup DNS server IP

to 192.168.1.1 on their Computer. If not, the device will perform as no DNS relay.
