Update local DNS resolver

With a Gateway location created, you have the ability to send traffic to your environment. You can test without risk by changing your DNS resolvers in your browser or network settings.

Change DNS resolver at the network level

To configure your device to send traffic to Gateway:

macOS

Windows

Linux

cat /etc/resolv.conf

nameserver 172.64.X.X
nameserver 172.64.X.X

iPhone

Android

Change DNS resolver in the browser

To configure your browser to send traffic to Gateway:

1. Obtain your DNS over HTTPS (DoH) address:

   1. Go to Gateway > DNS locations.
   2. Select the default location.
   3. Copy your DNS over HTTPS hostname: https://<YOUR_DOH_SUBDOMAIN>.cloudflare-gateway.com/dns-query

2. Follow the configuration instructions for your browser:

   Mozilla Firefox

   1. In Firefox, go to Settings.
   2. In Privacy & Security, go to DNS over HTTPS.
   3. Under Enable secure DNS using, select Max Protection.
   4. In Choose provider, choose Custom.
   5. In the field, enter https://<YOUR_DOH_SUBDOMAIN>.cloudflare-gateway.com/dns-query.

   Firefox is now configured to use your DoH endpoint. For more information on configuring DoH settings in Firefox, refer to Mozilla’s documentation ↗.

   Note

   If you want to enforce DNS policies through WARP instead of over DoH, you can disable DoH for your organization by blocking the Firefox DoH canary domain ↗.

   Google Chrome

   1. In Chrome, go to Settings > Privacy and security > Security.
   2. Scroll down and turn on Use secure DNS.
   3. Select With Custom.
