DSL-510 ADSL Router User’s Guide

DHCP

DHCP stands for Dynamic Host Control Protocol. The DSL-510 has a built-in DHCP server. The DHCP Server will automatically assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers on, they will automatically load the proper TCP/IP settings provided by the DSL-510. The DHCP Server will automatically allocate an unused IP address from the IP address pool to the requesting computer. You must specify the starting and ending address of the IP address pool.

DHCP Server: Click Enable to turn on the DNS forwarding service, which forwards to your LAN PCs the Domain Name System server addresses that your PPP connection learns from your ISP. This option can only be used when the Router is configured to act as a DHCP server for your PCs.

If you click Disable, you must configure DNS addresses manually on each PC or in the fields below.

Starting IP Address: The starting IP address for the DHCP server’s IP assignment.

Ending IP Address: The ending IP address for the DHCP server’s IP assignment.

Lease Time: The length of time for the IP lease.

DHCP Relay

In this mode the Router is an intermediary device or relay agent between a DHCP server owned by the ISP and host systems on your LAN.
