What aspect of client traffic does Split Tunnel primarily affect?

The focus of Split Tunnel is on how client traffic is managed in relation to corporate network resources. When Split Tunnel is configured, it primarily affects traffic bound for internal resources. This means that the traffic intended for the organization's network is securely tunneled through the VPN, providing a layer of security as it traverses the public internet.

When Split Tunnel is in effect, traffic that does not need to access internal resources—such as web browsing or accessing external sites—can go directly through the user's local internet connection rather than being routed through the VPN. This selective routing helps enhance performance by reducing bandwidth load on the VPN and allows users to access external resources directly without the overhead of the VPN connection.

This nuanced handling of traffic provides both security for sensitive internal resources and efficiency for general web traffic. Thus, the configuration effectively allows users to access both internal and external resources without compromising security for the internal traffic that is tunneled.
