To start taking advantage of Lumu Gateways, you need to configure your DNS resolver device to point all DNS requests to Lumu's IP addresses, substituting the automatic DNS servers provided by your internet service provider (ISP).

Once you have pointed your DNS to Lumu, all requests to resolve a hostname on the internet will be processed by Lumu against its proprietary intelligence including machine learning and artificial intelligence models to identify if your network is “talking” with adversarial infrastructure.

Remember to first register your public IP address or group of IPs as a Gateway for your company at the Lumu Portal before pointing your DNS to Lumu. 

Configuring Your DNS

We recommend doing this procedure on your edge DNS equipment , typically a router, DNS, or DHCP server in your company. Typically, the device that provides an internal non-routable IP address (DHCP) or the device that serves as your default gateway is also where you configure public DNS servers. Most often this will be a DNS server or a router—this might be your DSL router or cable modem if that is the only router in your network.

Remember to first register your public IP address or group of IPs as a gateway for your company at the Lumu Portal before configuring your DNS.

Before you change your DNS settings to use Lumu Gateways’, be sure to record the current DNS server addresses. It's important that you keep this data for backup purposes—just in case you need to revert to them at a later date.

Some ISPs hard-code their DNS servers into the equipment they provide. If you are using such a device, you will not be able to configure it to use Lumu. Instead, you can configure each one of your devices (desktops, servers, etc).

The process for changing your DNS settings varies according to the operating system (OS) and versions (Windows, Mac, or Linux) or the device (desktop, DNS server, router, or mobile device). For authoritative information, please consult the vendor documentation.
