1. Introduction
Wireguard is a cutting-edge VPN protocol that is known for its simplicity, speed, and security. It has gained a lot of popularity in recent years and is now considered one of the best VPN protocols available. However, if you want to get the most out of Wireguard, you need to know how to change your DNS server.
Changing your DNS server on Wireguard can improve your speed, security, and privacy. With the right DNS server, you can bypass geo-restrictions, avoid DNS leaks, and get faster connection speeds. In this guide, we’ll show you how to change your DNS server on Wireguard and provide you with some tips to help you choose the best DNS server for your needs.
2. What is Wireguard?
Wireguard is a modern VPN protocol that was created with the goal of being simple, secure, and fast. It was designed to replace traditional VPN protocols like OpenVPN and IPSec, which are often complex and difficult to configure.
Wireguard is much simpler than these protocols and uses fewer lines of code, which makes it easier to audit and maintain. It also uses modern cryptography, including the ChaCha20 stream cipher and the Poly1305 message authentication code. This makes it more secure than many other VPN protocols.
3. How does Wireguard work?
Wireguard works by creating a secure tunnel between two devices. This tunnel is encrypted, which means that no one can intercept or read the traffic that passes through it. Once the secure tunnel is established, all traffic between the two devices is routed through it.
Wireguard uses a concept called “cryptokeys” to establish and maintain the secure tunnel. These cryptokeys are generated when the connection is established and are used to encrypt and decrypt the traffic. Because these keys are constantly changing, it makes it much more difficult for attackers to intercept and decode the traffic.
4. Why Change DNS Server on Wireguard?
There are several reasons why you might want to change your DNS server on Wireguard. One of the main reasons is to improve your speed and security. By using a faster DNS server, you can improve your browsing speed and reduce the amount of time it takes for websites to load.
Another reason to change your DNS server is to avoid DNS leaks. When you connect to a VPN, all of your traffic is supposed to be routed through the VPN server. However, if your DNS requests are still being sent to your ISP’s DNS server, then your VPN connection is essentially useless. By using a different DNS server, you can ensure that your DNS requests are also being routed through the VPN.
Lastly, changing your DNS server on Wireguard can also help you bypass geo-restrictions. By using a DNS server in a different location, you can trick websites and online services into thinking that you’re located somewhere else. This can be useful if you’re trying to access content that is restricted in your country.
5. How to Change DNS Server on Wireguard?
Changing your DNS server on Wireguard is a relatively simple process. Here are the basic steps:
- Open your Wireguard configuration file
- Find the DNS option in the [Interface] section
- Add your desired DNS server (e.g. 1.1.1.1 or 8.8.8.8)
- Save the file and restart Wireguard
It’s important to note that not all DNS servers will work with Wireguard. You should check with your VPN provider or do some research to find a DNS server that is compatible.
6. Step-by-Step Guide: How to Change DNS Server on Wireguard
If you’re not familiar with editing configuration files, here’s a step-by-step guide on how to change your DNS server on Wireguard:
- Open your Wireguard configuration file
- Find the [Interface] section
- Add the DNS option (e.g. DNS = 1.1.1.1 or DNS = 8.8.8.8)
- Save the file
- Restart Wireguard
That’s it! Your DNS server should now be changed. You can test it by visiting a website like dnsleaktest.com to see if your DNS requests are being routed through the VPN.
7. Common DNS Servers for Wireguard
There are several DNS servers that are commonly used with Wireguard. Here are some of the most popular options:
| DNS Server | IP Address | Description |
|---|---|---|
| Cloudflare | 1.1.1.1 | Fast, private, and secure |
| 8.8.8.8 | Fast and reliable | |
| OpenDNS | 208.67.222.222 | Family-friendly and secure |
| Quad9 | 9.9.9.9 | Privacy-focused and secure |
There are many other DNS servers available, so you should do some research to find one that meets your specific needs.
8. How to Test DNS Server on Wireguard
Once you’ve changed your DNS server on Wireguard, you should test it to make sure that it’s working properly. Here’s how:
- Visit a website like dnsleaktest.com
- Run the test and check the results
If your DNS requests are being routed through your VPN, then you should see the IP address of your VPN server listed in the results. If you see your ISP’s IP address or a different IP address, then your DNS requests are leaking and you need to troubleshoot the issue.
9. Advanced Techniques: Changing DNS Server Based on Location
If you frequently travel to different locations, you may want to change your DNS server based on your location. For example, if you’re in the United States, you might want to use a different DNS server than if you’re in Europe.
To do this, you can use a script that automatically changes your DNS server based on your location. Here’s an example script:
if [ "$WG_INTERFACE" == "wg0" ]; then
if [[ "$(curl -s ipapi.co/country)" == *"US"* ]]; then
echo "Changing DNS to Cloudflare"
sudo wg set wg0 dns 1.1.1.1
else
echo "Changing DNS to Google"
sudo wg set wg0 dns 8.8.8.8
fi
fi
This script checks your IP address and determines your location. It then sets your DNS server based on your location. You can modify this script to use different DNS servers or to add more locations.
