Virtual Private Networks are becoming a necessity for many users, as threats related to privacy and
Internet security are becoming more evident when we talk about the online universe.
This is something that sometimes becomes a challenge even for the provider that provides us with the
Internet connection, so a good VPN can mask our activity and thus remain largely hidden. However, we
can face the inconvenience that certain websites and some Internet providers have begun to block VPN
connections by default, which prevents anyone from accessing content without first disabling it. But if
using a VPN in principle is legal, why block access?
Techniques to make your VPN Undetectable
Fortunately, there are ways to get around these VPN locks that do not involve deactivating the service,
as we will see in this article. Therefore, in some cases skipping these blockages can be quite simple,
although everything will depend on how the service detects and filters VPN traffic.
Among the most common methods and tools that are usually used to detect our VPN and deny access,
we can find the blocking by comparing the real IP with a list of addresses of that VPN already known.
On the other hand, data packets can be tracked where encrypted data passed from a VPN is analyzed to
check for unique cryptographic signatures, so if they are detected, the service can be immediately
Another known method is by blocking ports since each of them has an assigned number, so all you have
to do is to check the traffic coming from that port and then block it.
Change VPN settings
To greatly avoid these blockages, once we have the VPN configured and ready to use, there are some
important adjustments that we can make to increase security. This way we can make traffic virtually
undetectable without installing any additional software.
To begin with, keep in mind that the type of encryption used by the VPN can make a big difference,
where most implement the standard 256-bit AES with the OpenVPN protocol, which achieves a good
balance between speed and encryption. However, many of the blocking algorithms that we have
mentioned, work by checking OpenVPN traffic and block it. Therefore, by changing to a new encryption
standard, we can avoid firewalls to access any website.
The characteristics of the encryption protocol vary depending on the VPN we use, but it can be a good
way to make the VPN undetectable. Therefore, we can change the OpenVPN mentioned standard, for
others such as L2TP / IPSec, SSL / TLS or the SSH method.
Other alternatives to make your VPN Undetectable
On the other hand, to say that the ports used by the data work like a door or a tunnel that our device
uses to send information to our ISP or to the sites we visit, many of them already known, so they can be
blocked. Thus, it is also advisable to change the port that is used for traffic if our VPN has that option,
just use any these ports to remain hidden: 2018, 41185, 443, 80.
At the same time, the most advanced users in these areas have other alternative methods to make the
VPN undetectable, such as the use of an SSH tunnel, a highly recommended method for sending data by
having an additional layer of data. And this is rarely blocked or monitored, which makes it an excellent
way to hide the VPN connection and leave no trace, although we will lose some connection speed.
