The DNS servers can be discovered automatically through DHCP on the WAN interface OR
configured manually.
5.14.1 Configuring DNS Relay manually
To manually configure DNS Relay, go to the Configuration menu and select DNS relay. The
DNS Relay page is displayed:
Fill in the required DNS address and click on Apply. You will now see that the DNS address
is added. To delete the DNS address mark the box Delete? and click on Apply. Click Reset
to undo your selection.
When finished configuring DNS Relay, go to the Configuration menu and click on Save
config to save the new settings into the CopperJet.
Note: You need to fill in the CopperJet IP address as DNS server on your network card or
configure the DHCP Server and enable the setting: Use Router as DNS Server.
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.
