A virtual private network (VPN, is a secure network between two or more devices. It is generally used to protect data through a private tunnel. Your traffic through the VPN will always be encrypted with secure algorithms. These networks provide security against spies, and censorship of your current IPS or government.

A popular OpenVPN client for MacOSX is Tunnelblick. It can be obtained for free from OpenVPN client
Follow these basic steps to use Tunnelblick with OpenVPN VPNPTP Server:
Note: The first time Tunnelblick is run on a given Mac, it will ask the user for the an system administrator’s username and password. This is necessary because Tunnelblick must have root privileges to run, as it modifies network settings as part of connecting to the VPN. For more information on using Tunnelblick, see the Using Tunnelblick
To connect to VPNPTP Server from a Linux client computer, you need to follow these steps

Usually, the easiest way to install an OpenVPN client is to use the package management system for your particular Linux distribution. Run one of the following commands (as root):
yum install openvpn
apt-get install openvpn
Running the OpenVPN client with the downloaded client config file: Usually, the easiest way to install an OpenVPN client is to use the --config argument to specify the location of the downloaded client config file:
openvpn --config usa1-vpnptp_com.ovpn
Follow the next steps:
To connect to VPNPTP on an iPhone, iPad or iPod touch, you will need to install the OpenVPN Connect client and download our VPN configuration file (us1AND-vpnptp_com.ovpn). It is recommended to follow these instructions in order.
Download and install the OpenVPN Connect client (by OpenVPN Technologies) from the App Store.

The information on the internet and other networks is sent grouped in data packets. MTU (Maximum Transmission Unit) is the maximum amount of data that can be physically transmitted in a packet. Windows assigns a default value of MTU to each connection according to its type. However, it is necessary to check in practice if this value works properly in each connection.
If the MTU value set is too high, it can cause fragmentation and loss in the sent packets. Otherwise, if it is lower, the network capacity is not properly utilized. The MTU values assigned by Windows according to the network used are:
Each transmission unit consists of headers or headers plus the data used. The data referred to as MSS (Maximum Segment Size), truly define the information to be sent, so the formula would be: MTU = MSS + TCP & IP headers.
ping [-f] [-l
] [host] ping -f -l 1500 google.com
If result = Packet needs to be fragmented but DF set. You have to try until you fragment the package:
ping -f -l 1480 google.com Packet needs to be fragmented but DF set ....
ping -f -l 1460 google.com icmp_seq=0 time=1.883 ms icmp_seq=1 time=3.353 ms
As seen in the last ping there is no fragmentation so it is the correct MTU.
ping [-M do] [-s
] [host] ping -M do -s 1460 google.com
ping [-D] [-s
] [host] ping -D -s 1460 google.com
