By default, the primary WAN port is identified as port 1 on the back of the DNA, and the secondary WAN port is identified as port 2.


Labeling WAN Ports

1. Select the desired WAN Port from the Configured Networks pane shown in Figure 2.

2. At the top of the selected WAN port's card, enter a custom label. By default, each WAN port is labeled ISP 1 or ISP 2.

The following IP address modes are available:

  • DHCP: The DNA will attempt to dynamically assign an IP address to the port.
  • Static Address: The DNA will prompt you to assign the port a static IP address. See the Setting a Static IP section of this article for more information.
  • PPPoE: This mode is most commonly used for DSL connections. If selected, the DNA will prompt you for the username and password used to connect to your ISP.

When you are finished configuring your connection, click the Save Changes button.

Changing the Primary and Secondary WAN Connections

1. Select the desired WAN Port from the Configured Networks pane shown in Figure 2.

2. Select the Primary or Secondary radio button, depending on which value you would like to set for each port.

If you change Port 1 to Secondary, Port 2 will automatically switch over to Primary.
