When it comes to online security and privacy, using a virtual private network (VPN) has become increasingly popular. A VPN provides an encrypted connection between your device and the internet, ensuring your data remains secure.
However, one aspect that often gets overlooked is Domain Name System (DNS) resolution. DNS helps translate website names into IP addresses so your device can access those websites. By default, your DNS requests may not be as secure as you think when using a VPN because of DNS leaks, split tunneling, and misconfigured VPN clients. This is where setting up a DNS proxy server comes in handy.
What is a DNS Proxy Server?
A DNS proxy server acts as an intermediary between your device and the internet’s DNS servers. Instead of relying on the default DNS settings provided by your ISP or VPN service, you can configure your own proxy server to handle these queries. Doing so gives you several advantages, including improved privacy and the ability to bypass censorship restrictions.
Steps to Setting Up a DNS Proxy Server With Your VPN
Step 1: Choose Your Proxy Server Software
There are several software options available for setting up a DNS proxy server with your VPN. Some popular choices include Pi-hole, BIND9, dnsmasq, Unbound, PowerDNS, and Dnscrypt-proxy. Each has its own features and configuration options that cater to different user needs. It’s important to research and choose the right software based on factors such as ease of use and compatibility with your devices.
Step 2: Set Up the Proxy Server Software
Once you’ve decided on the software for your DNS proxy server, it’s time to install it on the device of your choice. This could be a dedicated server or an existing device such as a Raspberry Pi or Synology NAS. The installation process varies depending on the chosen software but usually involves downloading the necessary packages from official websites or package managers like apt or yum. Follow the installation instructions provided by the software’s documentation.
Step 3: Configure DNS Resolution
After installing the proxy server software, you’ll need to configure it to handle your DNS resolution. This involves specifying which DNS servers to query, setting up any caching or filtering options, and enabling DNSSEC for enhanced security. Refer to each software’s instructions on how to configure these settings correctly.
Step 4: Integrate with Your VPN Connection
To ensure that your VPN traffic goes through the DNS proxy server, you need to configure your VPN client or router as a custom DNS resolver. Most VPN providers offer an option in their client applications or router settings to change the default DNS resolver. Enter the IP address of your proxy server in this field, and save the changes.It will redirect all DNS queries from your device through the proxy server.
Step 5: Test Your Setup
After configuration, it’s important to test whether your DNS proxy server is working correctly. Visit websites like dnsleaktest.com or doileak.com to check for any unauthorized leaks. These tests will verify if VPN provider’s default DNS resolvers are not being used and instead pushed through your own proxy server.
Step 6: Monitor and Update Your DNS Proxy Server
Once your DNS proxy server is up and running, it’s important to regularly monitor its performance and update it as needed. Keep an eye on the logs and metrics provided by your software to ensure that there are no unusual activities or signs of potential security and data breaches. Stay informed about the latest updates and patches released by the software developers, as these updates may address security vulnerabilities or introduce new features.
Step 7: Configure Firewall Rules
To further enhance the security of your DNS proxy server, consider configuring firewall rules. By implementing strict firewall rules, you can prevent unauthorized access to your proxy server and ensure that only trusted users or devices can make use of it. Check the documentation of your chosen software or consult with a network support and security professional for guidance on how best to configure these firewall rules.
Wrapping Up
Setting up a DNS proxy server with your VPN can significantly improve your online security and privacy while also refining browsing speed and bypassing censorship restrictions. By following this step-by-step guide, anyone can take control of their own DNS resolution and ensure their internet activities remain protected. Remember to choose reliable software, properly configure it based on your preferences, integrate it with your VPN connection correctly, and test for leaks or potential vulnerabilities regularly.
