5.12 Configuring DHCP Relay

DHCP Relay provides a means for relaying DHCP and BOOTP requests from a subnet to

which no DHCP server is directly connected to one or more DHCP servers on other

subnets. The DHCP Relay Agent listens for DHCP and BOOTP queries and responses. When

a query is received from a client, DHCP Relay forwards it to the list of DHCP servers

specified. When a reply is received from a server, it is broadcast or unicast (according to

the client's request) on the network from which the original request came.

From the

Configuration

menu, click on

DHCP relay

. The

DHCP Relay

page is displayed:

5.12.1 Enabling/disabling DHCP relay

Click on the

Enable/Disable

button at the top of the page. If you click on the

Disable

button, DHCP server is disabled and the button changes to

Enable

.

Note: The Enable/Disable button is only visible when the DHCP Server of the CopperJet

is disabled. DHCP Relay only works when the DHCP Server is disabled.

5.12.2 Configuring DHCP relay on specific interfaces

You can configure DHCP relay to run on one or more specific interfaces. By default, once

enabled, DHCP relay operates on all available IP interfaces. You may set DHCP relay to run

on one of your LAN interfaces and the WAN interface, so that it can listen for replies from a

DHCP server at your ISP. This allows you to set DHCP server to run on a different interface

at the same time.

To specify an interface for DHCP relay to run on:

5.14.2 Automatically discover DNS Relay addresses

For configuring the automatic discovery of DNS addresses, a WAN Connection need to be

configured. See section

5.6 WAN Connections

for configuring WAN connections.

For both PPPoA and PPPoE connections, the CopperJet can discover the DNS addresses

automatically. The service provider will provide the DNS addresses through DHCP. In this

situation, there is no need to configure DNS Relay manually. Go to the

Configuration

menu

and select

WAN Connections

. The WAN connections that are defined are displayed. Edit the

preferred WAN connection by selecting

Edit

. The

WAN connection

page is displayed.

For PPPoA, select the

PPP

tab. For PPPoE, select the

PPPoE

tab.

Be sure that following options are set to

true

if you want the CopperJet to automatically

discover the DNS addresses.
