Labeling WAN Ports

1. Choose the desired WAN Port from the Configured Networks pane.

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 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.

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.

3. Click the Save Changes button.

Setting a Static IP

You can configure up to 16 WAN IP addresses per WAN port.

1. On the selected WAN card, choose the Static Address option from the Mode dropdown.

2. Complete all fields required by your ISP, and then click Save Changes.

Use the optional Additional IP Addresses field for 1:1 NAT.

The Subnet Mask drop-down menu lets you select masks from /17 to /31.

IMPORTANT  When using the Additional IP Address option, input the lowest possible value in the block as the Primary IP address value. Failure to do so will prevent the DNA from correctly routing VPN connections.

Setting Custom DNS

1. On the selected WAN card, click the Add Custom DNS option.

2. Choose Google Public DNS, OpenDNS, or Custom from the Nameservers dropdown. If you select Custom, you will be prompted to enter the information manually.
