The Ignoratus project uses open source available software to create a hidden VPN that can bypass almost all firewall systems. A skilled developer could design and implement something like this, but the aim here is to provide a simple guide for not so advanced users to use the project. With this, comes a well documented guide and a script that installs the system.
The software used in this project are:
wstunnel
dnslookup
Other software already provided in the Debin repositories, specially Wireguard and Python.
