Setting up DNS forwarding on a Linux client device is the configuration suggested for testing purposes. We recommend you configure your DNS server or your router to take the most advantage of Lumu Continuous Compromise Assessment on your entire network.

Requirements

1. A device running a Linux operating system.

Remember that for using Lumu DNS servers through Lumu Gateways collectors, you first need to register your public IP address or group of IPs as a gateway for your company at the Lumu Portal before configuring your DNS. If you are using Lumu Virtual Appliance (VA) as a DNS resolver, remember first to deploy and configure your VA.

Edit Linux DNS Settings

The DNS settings can vary depending on the Linux distribution. The following is a general overview of configuring DNS on a Linux client.

Go to the Linux system settings, then go to the Connections area of the Network section. On the IPV4 area, set Lumu DNS server addresses (or your Lumu Virtual Appliance IP, if applicable) in the Preferred DNS server and Alternate DNS server fields, respectively.

Example of Linux client connections settings

The Lumu DNS resolvers IPv4 addresses are:

50.17.0.10

3.87.85.24

Validate Your Settings

The final step is to verify that your DNS connections are correctly routed through Lumu. See Validate your new DNS Settings for more information.
