For security purposes L2TP protocol would be a reasonable choice due to its industry standard encryption algorithms that verifies integrity and encapsulates information twice.

To bypass firewalls, restrictions and censorship use OpenVPN or SothEther, they can also be used to secure wi-fi connections and public networks.

PPTP, which is native in most operating systems and devices, is a good choice for the cases when OpenSSL is not supported on your device.

SSTP is very secure and usually very strong AES and completely integrated into Windows (Windows 7, Windows 8, Windows 10). Mimics like a normal HTTPS connection, which in most cases can’t be banned.

The VPN encryption protocols used by virtual private network service providers, such as LimeVPN are measures of security for your online presence. Without being too practical, you should look for the most secure VPN protocol. However, you need to ask yourself one simple question, “Which VPN protocol is best?” The best VPN protocols are PPTP, L2TP, SSTP and OpenVPN.

Please make sure you are using one of the public DNS servers below on your computer/router in order to bypass DNS restrictions on your country.

We provide OpenVPN / SSL VPN protocol on TCP ports 80 (http), 443 (https), 992, 1194, 8888 and UDP ports 53 (DNS), 80, 992, 1194 and 8888. If you cannot connect with PPTP or L2TP protocol you can try to connect with OpenVPN with different TCP and UDP ports.

We also provide SSTP VPN protocol which uses standard SSL ports (https traffic and can’t be banned) so most likely if you can browse https web sites SSTP should work for you. Please be advised that SSTP protocol is supported only on clients with windows operating system Vista SP1, 7, 8, 2008 and newer. Unfortunately Mac OS, IOS and Android do not support Microsoft’s SSTP protocol yet.

There are various factors to consider as far as the choice of best VPN protocol is concerned. To begin with, security is one of the most important factors, along with VPN tunneling and authentication. Another important factor to consider is compatibility to client. You should take security consideration serious because it bypasses any physical precaution measures you might have in place. The best VPN protocols in the VPN protocols comparison list consist of: PPTP, L2TP, OpenVPN and SSTP.

What is PPTP Protocol?

This is one of the finest VPN protocols offering the best PPTP VPN security for internet users. Most VPNs are developed as well as managed by using the PPTP protocol, which is built on the functionality of PPP. This makes it possible to develop dedicated point-to-point tunnels through the internet. This VPN protocol works by incorporating one of several encryption standards. This protocol also provides foundation for the creation of L2TP.

What is L2TP Protocol?

L2TP is a well-known VPN tunneling protocol that uses tunneling to deliver data by authenticating a client in a two-phase process (authentication of the computer and the user). L2TP is normally paired with IPsec protocol. In case you are wondering what is IPsec protocol; it is a protocol for authenticating as well as encrypting internet traffic used in conjunction with L2TP.

What is OpenVPN?

Open VPN protocol is the best SSL VPN protocol and the fastest VPN protocol to use. You do not have to wonder which VPN protocol to use, because OpenVPN is just like PPTP or L2TP VPN tunneling protocols. As far as VPN tunneling protocols comparison goes, OpenVPN protocol is the best. This protocol has been ported to almost all operating systems, such as Mac, Linux and Windows.

What is SSTP Protocol?

SSTP is a new feature found in Windows Server 2008 along with Vista, which allows you to develop a VPN connection from a remote access client. By doing so, you are provided with the best SSTP VPN security. This protocol relies on the secure sockets layer for encryption, data integrity and encapsulation. The SSTP connection is a virtual private network tunnel, which behaves like L2TP and PPTP VPN tunnel.
