How To Make A VPN Undetectable & Bypass Blockers

If you want to find a solution to accessing the internet anonymously and securely every time then using a VPN could be the perfect solution for you. Your device will already have a VPN in place but it can cause blockages via detection, especially when it comes to venturing on websites that feature geo-blocking which can prevent access depending on where you are.

By using a VPN service, you can make your online footprint geographically invisible which will allow you to have access to a wider range of sites anonymously and securely with a minimized risk of detection, especially when browsing using public WiFi. However, know how to make a VPN undetectable and able to bypass blockers with ease.

The best VPN provider on the market is ExpressVPN which not only provides the best service in terms of security and ease of use but also has a 30 day returns policy so you can purchase it with peace of mind knowing that you will get your money back if you decide it’s not for you. In this guide, we’ll be discussing why VPNs are often blocked and how to bypass these blocks. 

Why VPNs Are Blocked

The first thing that is important to know is why VPNs are blocked. There are a number of reasons depending on what it is that you are looking for with some sites being blocked due to censorship and others due to copyright. Here are the most common reasons why VPNs tend to be blocked:


Firstly, VPNs are most likely to be blocked due to government censorship. A website could be blocked if it doesn’t conform to the cultural or moral values of a country.

There are countries that are stricter than others when it comes to censorship with China being among the strictest. China has applied what is called its Great Firewall which restricts access to a wide range of sites including Google, Youtube, various social media apps, and news sites among much more.

On top of this, China has also restricted the majority of VPN service sites meaning that those in China would find it extremely difficult to get around this block. Other countries that have strict censorship include Iran, Turkey, and the UAE as there are certain social media sites that are banned as well as VPN services.


The second reason is also the most common reason which is copyright infringement. This relates to sites such as Netflix which has differing libraries depending on the country so what is available on US Netflix is not guaranteed to be the same as the content on UK Netflix.

Other examples of copyright infringement could be sending and receiving files such as copyrighted movies and songs which have not to be paid for or are not available in your country.

If you do engage in illegal activity such as this and don’t have a VPN in place, your internet service provider will be able to see and will subsequently notify the authorities. 

Geographical Restrictions

Following on from copyright infringement, we have geographical restrictions which is another reason why Netflix may be different in each country. This rule mainly applies to streaming services as the distribution rights to certain content such as films, TV shows, and music may differ depending on the country.

This means that a film that is available to view in the UK on one platform may not necessarily be available in the US on the same platform. This is why companies such as Netflix have started to make their own content as it allows all users across the globe to access the same shows and films.

Having a VPN can allow you to alter your location anonymously and allow you to view services that are available in other countries although bear in mind that this is illegal and companies such as Netflix have made it even more difficult to bypass their geoblocking code. 

Professional Restrictions

Lastly, blocks can happen due to professional restrictions which are mainly applied by schools and workplaces to prevent students and employees from venturing onto social media or streaming sites when they are connected to the institution’s WiFi. 

Different Types Of VPN Blocks

Now that you know why VPNs are blocked, it’s important to know how they are blocked. This is to help further your understanding of how a new VPN can bypass these blockages. Here are the most common types of VPN blocks: 

Deep Packet Inspection (Known As DPI)

The first kind of VPN block is a Deep Packet Inspection which is known as DPI and is one of the more advanced blocks. DPIs work differently as they investigate the type of traffic rather than the location of the traffic.

Incorporating technology such as OpenVPN, DPIs apply cryptography signatures which can strip away a VPN’s anonymity. Even if they cannot identify the specific VPN, DPIs are able to see that they are equipped with a high level of encryption and therefore apply the block without having to rely solely on the location of the user.

This block is what China uses within the Great Firewall to minimize the number of VPNs use and is the main reason why finding and using a VPN is so difficult within the country. The way to avoid this kind of block is by having an option to alter your security settings within your VPN. 

IP Blocks

The most common kind of block used is the IP block. When a VPN is applied, it will display an IP address that matches the server’s meaning that geoblocking should be limited. However, it is not as simple as this, especially as companies find more ways to stop this from happening.

Streaming sites such as BBC iPlayer and Netflix have a log of VPN IP addresses and when that IP address is used to stream on their sites, it will be automatically blocked. Whether this happens or not depends on how secure your VPN is and whether it has the capabilities to bypass this block. 

Port Blocking

Lastly, Port Blocking is a technique that blocks VPNs that constantly come through the same port when accessing certain sites. Sites may have a list of ports that are known to route through VPNs such as port 1194 so the website simply monitors the activity from that VPN and is able to determine that the traffic should be blocked.

If you are caught and Port Blocked, you’ll be stopped from accessing that sight via or VPN or even without it. This type of block is not as common as DPI or IP Blocking and can easily be prevented by switching the ports that your traffic is filtered through. 

Bypassing VPN Blocks

Knowing how the VPNs are blocked is crucial because then you will have a better understanding of how they can bypass these blocks.

The first course of action is to make sure you have a quality VPN that comes with high security which will give it a better chance of getting around blocks undetected. Here are some of the best ways to bypass VPN blocks:

Changing Ports

The first thing you can do is changing ports. As mentioned earlier, one of the ways that VPNs are easily detected is because the traffic is constantly being filtered through the same port which makes it easier to be tracked and then blocked. Here are some of the ports that you should switch to:

Port 80

Firstly, Port 80 is the best choice for those who want a higher rate of encryption thanks to its high security making it reliable for all HTTP sites meaning that you have a minimal chance of being detected. Depending on what VPN you use, you may be able to utilize the SSTP protocol which provides an extra level of protection. 

Port 443

Secondly, Port 443 is another popular choice for those who have unencrypted traffic. This is especially useful for those making purchases online and wants to ensure that their financial and payment information is secure and not at risk of being leaked.

Using Port 443 provides a minimal chance of being detected when making payments so you don’t have to worry about any complications occurring when entering in your information. 

Changing Security Protocols

When researching which VPN is right for you, you’ll see that each service offers something different in terms of their security so knowing what level of security you want beforehand will definitely be best for you.

One of the best choices is OpenVPN thanks to its advanced technology, fast speeds, and high-security levels. However, it is not always the best when it comes to avoiding detection from blockers as lots of algorithms are set to detect OpenVPN traffic specifically.

There are some VPN services that offer fast speeds which can be ideal for those wanting to bypass any geographical blocks while others are better for providing anonymity and keeping your personal information and data secure and hidden from any leaks. 

Dedicated IP Address

Having a dedicated IP address can be great for those wanting to prevent detection. When you purchase your VPN subscription, you can choose to add on a dedicated IP address for an extra fee which will give you more security and will have a stronger chance of bypassing a higher number of different blocks while also ensuring that you avoid detection and blocks.

Dedicated IP addresses work by providing you with a specific IP address that isn’t used by anyone else meaning that it will come across that you are a regular user as they won’t be inundated with traffic using the same IP address or VPN.

This option costs more but is the best choice to consider as it provides you with all the security and protection you need to stay safe and anonymous on the internet without fear of detection or blocking. 


IKEv2 stands for Internet Key Exchange v2 which incorporates IPSec security as well as boasting faster speeds. If you are looking for a bypass for portable devices such as a mobile phone or tablet then this is the best option as it automatically reconnects you should you lose your connection.

The downside to this option is that it can be timely and difficult to set up as well as remaining compatible with a select few devices so make sure it works with your device beforehand. 

L2TP or IPSec

L2TP and IPSec are combined options that work differently with the former providing fast speeds but compromising security and the latter providing extra security with lower speeds.

It can take a long time to set these up and it is more inconvenient as it is a bypass option that comes with two different components so it is definitely among the weaker options in this list. Therefore, only consider this choice when you don’t have any other alternatives to choose from. 

Obfuscated Server

One of the most commonly used methods to bypass blocks is obfuscated servers. These are highly advanced servers that provide VPNs so you can be sure that they are not going to be detected.

Using a VPN connection provides you with the ability to bypass blocks, but your internet service providers and other third parties may be able to see that you are using VPN, although they won’t see what sites you are using it for.

Obfuscated servers hide the presence of your VPN connection altogether which means that no one will know that you have one and it will appear as though it is any other internet traffic. This means that you will appear as any other internet usage so you have very little chance of being blocked while also being protected with an extra layer of security that allows you to search anonymously at all times.

If you are searching from countries that have heavy use of censorship such as China, having an obfuscated server can be handy as VPNs are completely banned and since they use different ports each time, it makes it very difficult to detect you as it is impossible to keep an eye on every single port. 


One of the oldest solutions to bypass blocks is PPTP which should be used as a last resort due to its low security. This is because the technology in PPTP isn’t as advanced and although it has fast speeds, there is a high chance that you will be detected as well as an increased chance of your personal information being stolen or leaked, especially when using your device in a country that has strict laws regarding censorship.

Using PPTP can be good for those who want to bypass any geographical restrictions but be cautious when using this option as it does come with a lot of risks. 

Server Switching

If you find your VPN is constantly getting blocked by the same sites over and over, you can simply switch your server which will give your VPN a refresh and ensure that the sites have a tough time detecting your new VPN.

Making sure that you choose a VPN that has a higher number of servers will lessen the chances of your VPN specifically being detected and blocked and will also likely have more benefits when it comes to the security of your VPN. 


SSTP is an option that uses specific ports to bypass blocks making it a highly secure option. It filters traffic through port 443 which is one of the hardest ports to detect and is only available for those using Windows devices. 

Switching To Mobile Data

For those who are tired of website blocks in the workplace or are at school, you can bypass them by disconnecting from the WiFi and using your mobile data.

This will take away any restrictions that were in place when you were using the WiFi; however, bear in mind that this option will eat away at your data so if you have a limited amount of data in your contract, make sure that you are not using it too much to prevent high bills. 


Lastly, consider investing in WireGuard which is a newer alternative that combines fast speed with OpenVPN security so you can bypass an array of blocks. A fantastic choice for those who want higher security, they do offer select VPNs such as CyberGhost and only work on Linux devices so it is quite limited in terms of its products and versatility. 

Other Ways To Prevent Blocks

We’ve discussed the most common ways that you prevent any blocks but there are others, especially if you are more advanced with your technological skillset and want to boost the amount of protection your VPN has. Here are some of the other ways that you can prevent blocks:

SOCKS5 Proxy (Also Known As Shadowsocks)

Known as Shadowsocks, SOCKS5 Proxy incorporates the Socket Secure 5 protocol which transfers data via a proxy server. This means that there is an extra layer of security as the user is the only one that has access to the proxy meaning that you can be assured of anonymity and security when accessing the internet.

If you are wanting to share files via P2P, this is one of the best options as the proxies use remote servers which bypass any blocks which is ideal for those in countries that apply heavy censorship laws such as China.

This is because the traffic is filtered through a proxy server which gives you a new IP address so when accessing sites such as Google in China, they’ll be able to see the new IP address and not your actual one. This means that you have a layer of anonymity.

The downside to SOCKS5 Proxy is that it isn’t the most secure option on the list as it doesn’t have as high a level of encryption which means that the more you use it, the more likely it can be that you are going to be detected. However, this can be altered depending on what VPN you invest in as paid VPN is more likely to give you high-quality encryption that will combine with this proxy to offer flawless service.

Although this may cost more, it will ensure that you are as protected as possible when using the internet, especially if you are in a country with strict censorship laws. 

SSH Tunnel

If you are looking for an option that encrypts your traffic then an SSH tunnel is a good option to consider as it filters your data through various servers that allow it to bypass blocks undetected.

SSH tunnels can be made by using local port forwarding which is when your device is connected to another device to bypass the block. This can be handy if you are wanting to make purchases but want the data to be as encrypted and secure as possible so it doesn’t fall into the hands of hackers. It uses methods such as FTP which means that lots of different applications can be used without being blocked.

The slower speeds, however, mean that it isn’t ideal for certain uses such as streaming sites as you’ll find that it buffers so going for an alternative option that boasts faster speeds is best.

SSL/TLS Tunnel

Similar to SSH tunnels, SSL/TLS tunnels are great for those who want a high level of encryption as they deal with high levels of traffic and are ideal for protecting private data such as online banking, allowing you to transfer money safely.

You’ll find that many high-quality VPNs offer this anyway but having an SSL or TLS tunnel can provide extra benefits such as additional security and guaranteed anonymity.

Utilizing port 443 specifically, any sites that are monitoring this port will not be able to tell that you are using a VPN as it will disguise it as regular HTTP traffic meaning that you are just a regular user.

It can take a long time to set these tunnels up but they are easy to install and easy to use making them great for those who want to advance their protection in the easiest way possible. 

Tor Browser

Lastly, the Tor browser can be a handy option for those who are more advanced with technology as it is an open-source software meaning that you can access and browse on the internet anonymously.

Often associated with the dark web, the Tor browser simply adds a layer of security for its users by entering the traffic through the Onion Router which contains high levels of encryption to keep users anonymous. It is called the Onion Router because of the many layers of coding and encryption that it contains which makes it impossible to penetrate.

Bear in mind that the Tor browser on its own doesn’t provide 100% security as your IP address may be located at the entry and exit points which are always monitored by various agencies due to Tor’s connection with the dark web.

If you are wanting to use the Tor browser, then make sure you have opted for a VPN that boasts the highest level of security as well as an alternative IP address to ensure that you are being as secure as you can.

When researching which VPN is right for you, always make sure that you find one that is VPN Over Tor meaning that you will connect to the Tor network first and then the traffic is filtered through the VPN server.

This means you will have protection at the entry and exit points and will make it harder for sites to block you and difficult for hackers to expose your personal information. 

The Best VPN Service

Now you know everything there is to know about how VPNs work, how they can bypass blocks, and most importantly, the different types of blocks you can encounter, it’s time to research a variety of VPN services to find which one is going to be best for you and help to reduce your chances of detection and subsequent blocks.

There are a lot of options for you to choose from with paid and free options to suit all budgets; however, bear in mind that free VPNs have a much higher chance of detection because they are more limited in their benefits and are not as encrypted meaning that you are most likely to be detected at some point.

On the other hand, a paid VPN requires monthly payments which can be expensive, but you are guaranteed to have higher security and anonymity as well as better benefits which will make the VPN more successful. 

When it comes to determining which VPN service is the best of the best, it definitely has to be ExpressVPN. You’ve probably come across ExpressVPN before and with good reason. It is one of the most popular options because of the wide variety of benefits it provides.

ExpressVPN does require a paid subscription, but you get your money’s worth and more as they incorporate all kinds of techniques to bypass blocks while promoting fast speeds and high security. Here is everything you need to know about ExpressVPN:
