By default, CenturyLink dns will try to redirect your website to a proxy server if you’re using a custom certificate, such as the OpenSSL or PEM version.
However, you can configure CenturyLink DNS to redirect any website to your proxy server.
In this guide, we’ll show you how to configure your CenturyLink Domain Controller to redirect the DNS over TLS.
For more information on custom certificates and proxies, see How to Install a Custom Certificate.
For a detailed explanation of why you might want to use a custom DNS over HTTPS proxy, see Why You Should Use a Custom DNS Proxy.
You can also configure Centurylink Domain Controller as a reverse proxy for your own sites by using the “Custom Proxy” option in your Centurylink web interface.
If you do this, Centurylink DNS will attempt to use your own proxy server to redirect to your CenturyLogic server.
If this redirects to a domain name that you control, CenturyLogics DNS will redirect your traffic to that domain.
You should verify that your CenturyLinks DNS server is running on the same network as your CenturyServer.
CenturyLink does not automatically detect whether your DNS server supports reverse proxy support.
You must configure the reverse proxy in your DNS settings.
If the domain you want to redirect does not already support reverse proxy, you’ll need to configure the domain manually.
For instructions on configuring a custom reverse proxy to redirect DNS over the TLS protocol, see Reverse Proxy Support for DNS.
After you have configured your domain, you need to enable HTTPS for your domain.
When you set up your domain and HTTPS, CenturyLinks default proxy settings will be configured in accordance with the CenturyLink website configuration settings.
For details about configuring DNS over HTTP and HTTPS for specific websites, see Configure a Custom Reverse Proxy for a Specific Website.
To test whether your domain is configured correctly, go to https://www.centurylink.com/support and click on the Troubleshoot page.
This troubleshooting page will help you identify and troubleshoot issues.
If your domain settings work as expected, you will be redirected to the Troubled Sites page.
If they don’t, you might need to re-configure the proxy settings.
Once you’ve configured your reverse proxy settings, you should see your domain page, along with an HTTP Status Code of 503.
For an example of the status code displayed when your reverse-proxy settings are configured, see the example below.
If DNS server fails to forward traffic, click on Start Proxy Settings.
You’ll see a list of all the domains you have enabled in your domain controller settings.
You may also see the status of your reverse proxies on the Reverse Proxy Settings page.
After enabling the DNS, you may be redirected back to your web site if your reverseproxy settings fail to work properly.
This page is a page that allows you to verify that DNS over SSL is working properly, as well as to change DNS settings for the DNS.
If a DNS proxy settings page doesn’t work, try the TroubleHotshooting page.
You will see a Troubleshooting page, which you can use to confirm that your domain works as expected.
If all else fails, you must manually configure the DNS to allow traffic to go through the CenturyLogix proxy server that is listed in the next section.
