Split Tunneling

What Does Split Tunneling Mean?

With split tunneling, a user can simultaneously access a public network while connected to a virtual private network. In other words, it provides a multi-branch networking path. The public network could be any network like a local area network, wide area network or even the Internet.


Using split tunneling often depends on the business’ needs and helps in securing the data traffic of users working in a remote login environment. Split tunneling can provide a much-needed network speed and performance boost in a multi-network environment.

Techopedia Explains Split Tunneling

Once the virtual server is aware that split tunneling is implemented, it alerts the client and the traffic is directed through the specific tunnel.

Split tunneling can keep a strict separation between private and public networks by enforcing its policies. It is highly capable of minimizing the bottlenecks involved in communications. It can also preserve the bandwidth associated with the virtual private network.

Split tunneling can help the virtual network to handle lighter workloads with the help of gateways, servers and clients as it allows transmission of data which needs a virtual private network protection. Configuration of specific network routes are possible in split tunneling and can be downloaded to the client.

When split tunneling is enabled, security measures need to be tightened, as outside attacks are possible and the network could be vulnerable if such measures are not taken.
