Virtual Private Networks, or VPNs, are a method of employing encryption to allow users to access a private network securely and share data remotely through public networks. Though VPNs connect over public interfaces, it’s secure and appears as a private network. Because VPNs offer an inherent increase in security, they are often used by enterprise corporations as a way of connecting to remote data centers. If you’d like to read up about VPNs further, head over to our What Is a VPN series.

This article will guide you through connecting to your Managed Atlantic.Net VPN.

Required Applications

Whether you’re connecting from a Windows, OSX or Linux desktop, there are many software applications available that can be used to connect to a Mobile IPSec VPN. Some systems are already designed to support connection to Mobile IPSec while other systems require additional software to be installed.

When available, it’s recommended to use the vendor-supplied default VPN clients. Most modern phones, especially the newest Android and Apple devices, support Mobile VPN connections natively. Apple’s OSX desktop and laptop systems also natively support Mobile VPN connections.

For Windows systems, Atlantic.Net recommends using the Shrew Soft VPN Client.

Set up ShrewSoft VPN for Windows

The first thing you’ll need to do is download the latest version of the Shrew Soft VPN client on your Windows workstation. Go to; about half-way down the page is a listing of all available Stable Releases.


Once you have the installer downloaded, double-click (execute) the installation package.


Select “Standard Edition” and press [Next].


Select [I Agree] to accept the terms of the License Agreement.
