Topic

This article describes the Static Host Mapping feature of the Datto Networking Appliance (DNA).

Environment

  • Datto Networking Appliance

Overview

The Static Host Mapping feature allows an operator to specify an IP address to resolve for a given hostname when queried by an internal client on the LAN. In the networking field, this feature is sometimes called "DNS Host Override" or "DNS Static Host Mapping."

To access the Static Host Mapping card, log into the DNA web interface, and click Security, as shown in Figure 1.

To add a mapping, click New Mapping, and configure the following settings:
  • Hostname: Enter the fully-qualified hostname that you want to map to an IP address.
  • IP Address: Enter the IP address that you want the hostname to resolve to. You can use any valid IP address.

To add another rule, click New Mapping. Once you have finished configuring the rule, click Save Changes. The DNA will apply the rule globally.
