VPN Split Tunneling – By default, a VPN secures all of your network traffic.  So if a VPN is connected to a machine (PC – Laptop – Router) then all software, apps and other machines take advantage of the secured connection.

The principle of Split Tunneling VPN is to cut the encrypted connection for certain applications or software. You can have a browser that uses the secure VPN tunnel and another that uses your IP ISP. This is the basic principle.

What are the advantages of Split Tunneling?

  • Gives great flexibility to your network.  You have two lines, one secure and one not.
  • Some software such as newsreaders that allow you to access the Usenet network have not interest in using the VPN.  The Usenet network is already secured by the SSL VPN and cause you to lose the connection speed.
  • Avoids having to log off to go to some sites.
  • Greatly simplifies the sending of mail with a VPN!

Unfortunately, this feature is not present among most of the VPN vendors with the exception of PureVPN. PureVPN is one of the top VPN providers with more than 500 servers all over the World. They provide a lot of options and additional services like SmartDNS.

Firefox launched from the client will give you an IP NL in the case of a connection in the Netherlands.  The same Firefox from your desktop will give you your ISP IP address.

Warning: This feature (full of promise) is in Beta.  Before using it blindly you should check that the application launched from the client is effectively secured because eg IE does not work.
