DSL-500G ADSL Router User’s Guide

DHCP Service Modes

DHCP services can be employed in one of three different ways; it can provide DHCP services, it can receive

DHCP services or it can relay DHCP service. By default the device is configured to act as a DHCP server on the

Ethernet LAN. In this case it will supply IP settings to hosts that are configured to receive IP settings from a

DHCP server.

The device may also be configured to relay IP settings from your ISP’s DHCP server. In this case, you will want

to configure the client hosts on your LAN to automatically obtain IP settings.

Finally the Router can perform no DHCP function at all. In this case, it will need to be either manually assigned

IP settings or receive them from a DHCP server on your LAN or from the ISP (see previous section).

Figure 8. DHCP Mode Configuration

Choose one the options below from the DHCP Mode: drop-down menu.

DHCP Server

This is the default mode for the Router. In this mode it provides DHCP

services to properly configured hosts on the Ethernet LAN.

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.

none

In this mode the device does deliver or relay any DHCP services. If you

choose this option and are operating in Router mode you will need to

supply IP settings to the device manually (see previous section).

Click the Submit button to save the settings in temporary memory. When you are done making changes to the

configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to

permanent memory.
