How to bypass VPN blockades


While VPNs are the most secure and most effective method to circumvent censorship bans as well as geographical restrictions, some businesses and government agencies are still trying to restrict Internet access, and remain an inch ahead. Anti-VPN technology will identify and stop VPN traffic on local networks and websites and reduce the efficiency for the VPN.

Blocking VPNs

Internet enemies like China, Iran, Russia, Syria, and Egypt are currently focusing on blocking VPNs. a means to stop encrypted protocol tunnelling that makes online users secure.

Internet services like Hulu, Netflix and BBC iPlayer are doing the same, stopping users from accessing VoD by using the use of a VPN service that allows them to unblock content restricted to a specific region.

It’s bad enough that users needed to look out for journalistic policies and leakage concerns However, they now have to ensure they are using a VPN they select is secure against blocking such content.

The main goal of using VPNs VPN is to ensure that you keep your identity private even in countries where they strictly enforce certain data for the general public.

This is where the feature called “blackout” is useful and is a.k.a. “StealthVPN” offered by the majority of companies on the market This feature lets you avoid VPN blocking.

Therefore, this guide is for those who are that are privacy-conscious and living within “Internet Enemy” areas. This guide will give you the details about the confusion surrounding it, how it functions and the many ways it can be used!

The reasons behind blocking VPN traffic can be a myriad of reasons, from copyright protection as a means to block the Internet. As of 2017, Chinese officials have ordered ISPs to stop all VPN services to bypass the “Great Wall of China”. Similar methods, though at a lower scale are used by corporations as well as schools to block internet activity.

What exactly is an obfuscation?

From a user’s perspective, Obfuscation is the process of using various technology and software codes in order to make something difficult to comprehend.

Many products and services employ obfuscation to safeguard intellectual property and to prevent attackers to break proprietary software.

The process can involve encrypting code, changing variables into useless labels and adding unneeded code to an application library or even the removal of metadata.

Obfuscators are typically used to automate the conversion of simple programming code in a way that performs in the way it was originally designed, however, it is difficult to understand or read…

Obfuscation is an extremely reliable method of blocking VPN traffic by hiding the data as normally unencrypted traffic, which allows users to circumvent VPN blockages.

It accomplishes this by hiding the entire request sent and received behind the standard HTTPS (Hypertext Transfer Protocol Secure) encryption, for instance, when you connect to a banking website via port 443.

What are the ways a VPN employs encryption?

VPNs enable the internet to travel through a safe and secure tunnel. They also conceal your location by providing you with an entirely new IP address, that is linked to the server you connect to, thereby keeping your identity hidden from the eye of government agencies as well as cybercriminals and copyright hunters.

This is one of the reasons VPNs are extremely well-liked by digital nomads as well as everyday people. They are blocking ports, IP addresses DNS and protocols. However, VPNs themselves are a target in countries that use Deep Packet Inspection (DPI) to block targeted applications/protocols.

By relying on the packet type instead of port numbers You will not be able to get complete protection against bans until you employ “obfuscation”. Below is an illustration of what is a typical connection when using OpenVPN. OpenVPN protocol.

Obfuscation operates in a totally different way, and it uses pluggable transports that redirect traffic into tunnels that are more difficult to trace or navigate.

The majority of VPNs utilize an OpenVPN protocol in order to enable “XOR Entanglement” a.k.a. OpenVPN Scramble. This is highly effective to protect against the deep packet examination (DPI).

OpenVPN Scramble uses the XOR encryption algorithm to break sophisticated VPN blocks in nations like China, Iran, Russia, Syria and Egypt.

The XOR Cypher

Pronounced “Ex-or” XOR” stands for Exclusive or. It’s a mathematical operation that utilizes the XOR Cypher, which replaces each alphanumeric character of the string with a different number.

Since the algorithm can be reversed it is possible to pass your output data back to the same Cypher, and it will erase the original string as well as the cypher that was deleted.

This kind of cypher employed by XOR is also referred to in the “Additive Cipher” or ROT13 It is utilized by smart technicians to create hidden messages.

How efficient is OpenVPN Scramble? (XOR Obfuscation)?

If you are connecting to a server using XOR Obfuscation, the data encrypted by OpenVPN using XOR Cyphers can be difficult for DPI and other systems such as The Great Firewall to identify themselves.

This is one reason it’s earned quite a name on the VPN market since it employs a simple approach to implementation.

It is also possible to find malware makers using obfuscation in order to hide their harmful code fragments from detection. They use a one-byte value which acts as a “key”.

The code that is obfuscated is encoded into each bit of data, and then XOR’ing every byte of data with the chosen key. But, keys with longer lengths can be utilized, and this is what the majority of VPNs employ.

Generally speaking, the effectiveness of XOR to scramble data is dependent entirely on the randomness of the key it employs and this is why it’s so effective as well as demonstrated by its extensive use of it.

You could even conduct tests. You can switch on a standard VPN and then test it using Wireshark. The connection will be treated as OpenVPN. If obfuscation is enabled, Wireshark will no longer recognize the traffic as OpenVPN.

It is the XOR Obfuscation argument

It is undisputed there is no doubt that the XOR Obfuscation is extremely efficient in enhancing your privacy online, by securing your privacy from government attempts to stop OpenVPN traffic.

It’s more precise to establish the quality of your VPN connection when you combine the XOR Obfuscation feature, however, there are some who argue that it might not always be efficient.

This is why openvpn_xorpatch is been not supported by the implementation in any version that is official of OpenVPN and ISPs make themselves patches that deal with issues with the VPN problem of blocking.

“We don’t advocate this strategy since there’s a more efficient solution that is used in users of the TOR community. It’s a program called obfsproxy that can be used with OpenVPN without the need to recompile OpenVPN.”


VPN blockades

  1. Blocking via IP address

    If you are connected to the Internet through a VPN websites will look up an IP address from the proxy server, not the actual device. Netflix as well as other businesses analyze IP addresses with databases of well-known VPN server addresses or shares addresses and stop these addresses. To prevent this from happening, VPN providers regularly change the IP addresses of their servers.

  2. Blockage of ports

    To block access to the VPN administrators of networks may block ports that are often utilized to access VPN services. The easiest method of avoiding this blockage is to use alternative ports.

  3. Deep Packet Inspection (DPI)

    The DPI technique analyzes all traffic that is on the network to find VPN traffic. It then blocks or logs it, and redirects the traffic.

How can I bypass VPN blockers?

Without further delay, we’ll discuss possible solutions. Here are the seven most efficient methods to get around VPN blockers.

  1. Consider a different VPN server (or other VPN service)

    Businesses and websites can block certain IP addresses of the most popular VPNs, but nobody has the resources or time to ban all VPNs. If you find that the VPN you’re using isn’t working Try switching to a less well-known VPN (you can check out our guide to the top free VPN trials to test this). If your IP address cannot be used, change to an alternative IP address with this same VPN provider by connecting to another server.
    To find the VPN with the largest number of servers, you must follow the link. With a variety of servers, These VPNs also have a huge range of IP addresses. This means you are able to switch between various IP addresses with ease. We’ll also offer some additional suggestions for different VPNs However, you can begin by exploring the top VPNs as they’re all known for providing huge numbers of IP addresses.

  2. Make your very own VPN server

    If you are a fan of playing with software and hardware it is worth the creation of your own VPN server. It’s not something that requires an IT specialist. There are numerous useful articles and tutorials available on the Internet on how to create customized VPN servers. All of them make the process straightforward.
    You can guess that TechNad is concerned with privacy and security concerns relating to VPNs. That being said we’ve put together our own guide for creating the VPN server in your home. Make sure you go through it.

  3. Use a different VPN protocol

    The VPNs of today offer an array of protocols that have been designed to meet different requirements. While some of them place your security and privacy first while others compromise and deliver high performance. There’s a wide variety of VPN protocols, including OpenVPN, L2TP, PPTP, SSTP and others. If you’re interested in learning more about these protocols, make sure you go through our guide on VPN protocols.
    Depending on the VPN application that you’re using, you’ll be capable of switching to the latest protocol. It’s done by going to the VPN settings page and choosing an option. It’s as easy and could be one of the most straightforward solutions to the question of how to circumvent VPN blocking.

  4. Switching between various VPN ports

    Ports are docking stations used to regulate the flow of data. In the case of VPN software being involved, ports are used by different protocols to control the way your outgoing and incoming web-based data is dealt with. When you close the port, you block the flow of data, which is a method to restrict accessibility to VPN applications. Therefore, the best option is to choose an alternative port.

    • The TCP port is 443 If you go to websites that require important details, such as your credit card information Your Internet connection will use port 443 (used by HTTPS) which is the standard encryption protocol. The port is nearly never blocked as online purchases or exchanges of crucial data are not possible without the use of this port. Port 443 is also more difficult to spot for websites by using Deep Packet Inspection (DPI). The option to change this port’s number is provided in nearly all VPN software. If your VPN software doesn’t permit you to change your port’s number, then you are able to change it manually by editing your OpenVPN Configuration file. But, it is recommended to consult with your VPN provider prior to making any modifications.
    • Port 80 of TCP: Port 80 is utilized to run the HTTP protocol, which is the basis on which virtually every website operates. The port is not blocked, however, Deep Packet Inspection can easily find VPN traffic through this port, block it, and stop it from going through this port.
    • Stealth VPN: Sometimes even ports 443 can be used to detect VPN use since the majority of VPNs contain a data-packet header that allows firewalls to recognize their presence. VPN providers are aware that some websites are able to recognize VPN traffic using port 443, which is why they’ve devised the method known as “Stealth VPN”. It conceals your VPN traffic and disguises it as normal traffic thus allowing users to access websites on port 443 without being identified. Stealth VPN can rewrite data headers in packets to ensure that VPN traffic isn’t recognized by the site.
  5. Use different software

    Additionally, if you want to use as well as using a VPN to get around any blockchains, there are various types of software you could look at. All of them are made to protect you from unauthorized access, and they do this by using various forms of technology. Here’s a brief review.

    • It is the Tor browser: Tor is an internet browser that permits users to browse the internet in complete anonymity. Tor nodes are easily blocked, however, you can get around IP blocking through Tor bridges. It is also possible to bypass Deep Packet Inspection (DPI) through a technique called onion routing. It forwards messages via the ‘network of repeaters’ operated by volunteers. It is possible to install Tor Browser for free.
    • Shadowsocks The proxy or application is quite widespread in China. Shadowsocks is an open-source proxy software that is used in China for accessing websites with censorship. This is an anti-GFW as well as SOCKS5 proxy server that was created by a Chinese developer. This is why it’s extremely popular in the country.
    • Psiphon is another open-source program designed to break VPN blockers. Psiphon is a blend of various VPN, SSH, SSH+ and HTTP Proxy technology. If you’re using a VPN and you aren’t able to access websites due to a VPN blocker You can alter preferences for SSH and SSH+. One of the reasons why people enjoy this application most is that if you find that the Psiphon site is not accessible in your region You can contact them via email and request that they give you the program.
  6. Make use of an SSL/SSH tunnel.

    SSL, as well as SSH tunnelling, offer two ways of routing your website traffic across different types of secure connections. Though they require manual configuration the VPN service provider is happy to assist you with setting up these customized encryption systems.

    • SSL tunnelling: Tunnels using SSL and TLS are created using Stunnel software. SSL and TLS tunnels are utilized in HTTPS (e.g. in online stores). If you connect to the VPN server by using SSL or TLS it becomes hard for sites to tell whether you’re using HTTPS as well as VPN traffic. You should make contact with the VPN provider to set up SSL or TLS tunnels since they require installation on both the client’s computer as well as the server. AirVPN is a well-known program that lets you build SSL as well as TLS tunnels with ease.
    • SSH Tunnelling: SSH tunnelling is identical to SSL tunnelling in a variety of ways. It also makes tunnels, however, it makes use of the SSH (Secure Shell) tunnel instead of SSL or TLS. SSH is crucial in the world of business which is where it’s utilized to connect to the shell account on UNIX systems. It’s not as widely utilized as SSL however it is an effective method to gain access to blocked websites. To enable it you have to connect with the VPN company.


  7. Switch to mobile data using tablets and smartphones

    If VPNs are not allowed at your workplace or school then you won’t be able to utilize this kind of software to access blocked websites. You can however switch to an Internet connection that isn’t blocked. Therefore, instead of using your school’s or office’s Wi-Fi network, you must use your mobile plan offered by your service provider (on your tablet or smartphone).
    It’s a simple method and does not require any advanced skills or expertise. Simply turn off Wi-Fi and connect to the Internet using your mobile. Your service provider may be charged however, you’ll have access to websites such as Facebook as well as Twitter. You can also connect your mobile to your smartphone and connect it with your computer through a modem.

Which VPN do I utilize to get around the VPN blocking?

Let us offer you some suggestions. After having tested a wide range of VPN services, we have a clear idea of the ones that are most effective in battling VPN blockers. Here are the top five VPNs to get around VPN blocks.
