The following IP address modes are available:

  • DHCP: The DNA will attempt to assign a dynamic 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: DSL connections commonly use this mode. 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. Click 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.
