Undoubtedly, PPTP VPN is the easiest protocol to set up and is also very useable. But this protocol works via port:1723 using GRE and that is its weak point. In some countries what often happens is that major internet services providers (ISPs) or corporative firewalls disable port:1723 and GRE which is incompatible with the PPTP connection. Frequently more popular protocols like L2TP\IPSec do not function in a particular network. For instance, in an office or a hotel in which the web administrators authorize only Web traffic (port:80[http] and port:443[https]).

We offer you an easy solution for this problem. Open VPN, a traffic tunneling protocol that works with any kind of open port.

A VPN, or Virtual Private Network, is a cryptosystem that allows you to secure your data as it travels over an insecure network such as the Internet.

While this may sound similar to the SSH cryptosystem, VPNs have a different purpose. As far as users are concerned, they will be able to do anything they normally would be able to do even when they are away from the network. Because of this, VPNs are popular with telecommuters and with offices that need to share resources over physically separate locations.
