split tunneling(split tun´&l-ing) (n.) The process of allowing a remote VPN user to access a public network, most commonly the Internet, at the same time that the user is allowed to access resources on the VPN. This method of network access enables the user to access remote devices, such as a networked printer, at the same time as accessing the public network.
An advantage of using split tunneling is that it alleviates bottlenecks and conserves bandwidth as Internet traffic does not have to pass through the VPN server. A disadvantage of this method is that it essentially renders the VPN vulnerable to attack as it is accessible through the public, non-secure network.
