The official servers allow the passage of any IPv4 protocol, whereas the SSH connection of private servers allows only the passage of TCP, UDP will only be possible on private servers if the server is running any UDP Gateway such as badvpn-udpgw, without the connection UDP, you will not be able to play some games online or access some services.

It is also possible to use your own server through SSH, (Private Server option), in the standard method using port 22 (SSH standard), or with connection text and SNI if the server is prepared to receive these types of connections.

To use it, no registration or payment is required, just a functional internet connection or knowledge to go through your provider's restrictions in case your access is blocked. The available official servers use a proprietary protocol that we call TLSVPN, it is a simple protocol that protects the connection using TLS 1.3 (and TLS 1.2 optionally), the same used in HTTPS sites, with a self-signed certificate verified at the time of connection to avoid interception. TLS Tunnel is a free VPN that aims to cross barriers imposed by internet providers and governments, and to guarantee privacy, freedom and anonymity to users.
