Configuring the management interface (Transparent mode)
In Transparent mode, you can configure the management interface for management access to the DFL-500
NPG.
•
Go to System > Network > Management .
• Change the Management IP and Mask as required.
These must be valid addresses for the network from which you will manage the DFL-500 NPG.
•
Select the management Access methods for each interface.
By default in Transparent mode, you manage the DFL-500 NPG by connecting to the internal
interface. However, you can configure the management interface so that you can manage the DFL-
500 NPG by connecting to any interface.

• Go to System > Network > DNS .
•
Change the primary and secondary DNS server addresses as required.

Adding routing gateways
The first step in configuring DFL-500 NPG routing is to add routing gateways. Routing gateways are the
gateways on your network that you want to route DFL-500 NPG traffic to. You can add the IP address of each
routing gateway, and you can also optionally configure the DFL-500 NPG to ping the routing gateway at a
specified time interval to make sure that the DFL-500 NPG can communicate with the routing gateway.
To add a routing gateway:
• Go to System > Network > Routing Gateway .
• Select New to add a new routing gateway.
•
Enter the IP address of the routing gateway.
This IP address should be on the same subnet as the DFL-500 NPG interface that connects to this
gateway.
• Select Dead gateway detection if you want the DFL-500 NPG to confirm connectivity with the
gateway.
