Shield Your DNS Traffic With DNS Over HTTPS (DoH)
When you're surfing the web, your browser sends requests over the Internet to look up the right IP address for whatever sites you're visiting. Traditionally, these requests are sent to servers over a plain text connection, making it easy for third parties to spy on what website you're about to access.
Firewalla supports DNS over HTTPS (DoH), a protocol for performing DNS requests via the HTTPS protocol. DoH encrypts your DNS traffic, helping you protect your privacy.
How does DoH work?
DoH securely sends the domain name you type into your browser to a DoH-compatible DNS server. With Firewakka, when you enable DoH for a device on your Firewalla, it will use the DoH server even if it configures its own DNS server.
How do I enable DoH?
To start using DoH, tap on the 'More' button on your Firewalla's main page, or go to 'Settings' and tap on 'Features'. Tap on the 'DNS Service' feature and toggle DoH on. You can select which devices to apply DoH to, and which server (Cloudflare, Google, Quad9, OpenDNS) will handle the DoH queries.
You can also add customized DoH endpoints if you want to use a provider other than the defaults provided in the app. You can add them by tapping 'Servers', then tapping 'Add Server.' Give your new server a name, enter in the endpoint URL or stamp, then tap Save.
You can select multiple DoH servers, and Firewalla will automatically pick the fastest one to use.
Can I use DoH with other DNS services?
While you can't run two different DNS services simultaneously on one device, you can enable additional DNS services simultaneously on other devices. For example, you can run DoH for your laptop while running Unbound for your tablet.
