Note: If you change the start or end values, make sure the values are still within the same subnet

as the gateways IP address. In other words, if the gateways IP address is 192.168.1.1 (default)

and you change the DHCP start/end IP addresses to be 192.128.1.2/192.128.1.100, you will not

be able to communicate to the ADSL Router if your PC has DHCP enabled. In addition to the

DHCP server feature, the ADSL Router supports the DHCP relay function. When the ADSL

Router is configured as DHCP server, it assigns the IP addresses to the LAN clients. When the

ADSL Router is configured as DHCP relay, it is responsible for forwarding the requests and

responses negotiating between the DHCP clients and the server.

By turning off the DHCP server and relay the network administrator must carefully configure the

IP address, Subnet Mask and DNS settings of every computer on your network. Do not assign

the same IP address to more than one computer and your ADSL Router must be on the same

subnet as all the other computers.
