Configure the data interface

For a security connector that’s used as a DNS sinkhole, the data interface defines where in your network malicious or suspicious traffic is directed. For the DNS Forwarder, the data interface is the IP address of the DNS forwarder.

By default, the data interface is configured to use the Dynamic Host Configuration Protocol (DHCP). As a result, these settings may already be configured. You can configure a static configuration. If you select a static configuration, make sure that you provide a valid IPv4 address. Currently, the security connector does not support IPv6.

Note: As a best practice, if you are setting up a DNS forwarder, make sure that you use a static configuration for the data interface.

How to

  1. If you are on the security connector main menu, press 2 or use the arrow keys on your keyboard to select Configure Networking and then press Enter. If you are on the Networking menu, go to step 2.
  2. In the Networking menu, press 2 or use the arrow keys to select Configure Data Interface and then press Enter.
  3. Press E to edit the existing settings of the data interface.
  4. To use a static network configuration:
    1. For the Data IP Mode, enter S, and press Enter.
    2. For the Data IP Address, enter an IP address, and press Enter.
    3. For the Data Subnet Mask, enter a subnet mask address, and press Enter.
    4. For the Data Gateway IP, enter an IP address, and press Enter.
  5. To use a DHCP network configuration, enter D in the prompt for the Data IP Mode, and press Enter.
  6. Enter y and press Enter to confirm that you want to apply the changes.
  7. After the changes are applied, press Enter to return to the networking menu.
