# 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

Linux

Terminal window

```

cat /etc/resolv.conf


```

```

nameserver 172.64.X.X

## 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 **Traffic policies** \> **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 ↗](https://support.mozilla.org/kb/dns-over-https).  
Note  
If you want to enforce DNS policies through the Cloudflare One Client instead of over DoH, you can disable DoH for your organization by blocking the [Firefox DoH canary domain ↗](https://support.mozilla.org/kb/canary-domain-use-application-dnsnet).  
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**.  
   4. In the **Enter custom provider** field, enter `https://<YOUR_DOH_SUBDOMAIN>.cloudflare-gateway.com/dns-query`.  
Read more about [enabling DNS over HTTPS ↗](https://www.chromium.org/developers/dns-over-https) on Chrome.  
Microsoft Edge  
   1. In Microsoft Edge, go to **Settings**.  
   2. Select **Privacy, Search, and Services**, and scroll down to **Security**.  
   3. Turn on **Use secure DNS**.  
   4. Select **Choose a service provider**.  
   5. In the **Enter custom provider** field, enter `https://<YOUR_DOH_SUBDOMAIN>.cloudflare-gateway.com/dns-query`.  
Brave  
   1. In Brave, go to **Settings** \> **Security and Privacy** \> **Security**.  
   2. Turn on **Use secure DNS**.  
   3. Select **With Custom**.  
   4. In the **Enter custom provider** field, enter `https://<YOUR_DOH_SUBDOMAIN>.cloudflare-gateway.com/dns-query`.  
Safari  
Currently, Safari does not support DNS over HTTPS.
3. Verify that third-party firewall or TLS decryption software does not inspect or block traffic to the DoH endpoint: `https://<YOUR_DOH_SUBDOMAIN>.cloudflare-gateway.com/dns-query`.
