Split tunneling is a feature in virtual private networks (VPNs) that allows users to access the internet directly without having to go through the VPN tunnel. This can improve browsing speeds and reduce latency, making it a desirable feature for many organizations. Fortigate, a popular network security platform, supports split tunneling, but enabling it requires some configuration. In this article, we will delve into the world of Fortigate and explore how to enable split tunneling, its benefits, and the potential security implications.
Introduction to Fortigate and Split Tunneling
Fortigate is a comprehensive network security platform that offers a wide range of features, including firewall, VPN, intrusion prevention, and antivirus protection. It is widely used by organizations of all sizes to protect their networks from cyber threats. Split tunneling is a feature that allows users to access the internet directly, bypassing the VPN tunnel. This can be useful for several reasons, including improved browsing speeds, reduced latency, and increased productivity.
Benefits of Split Tunneling
There are several benefits to enabling split tunneling in Fortigate, including:
- Improved browsing speeds: By allowing users to access the internet directly, split tunneling can improve browsing speeds and reduce latency.
- Increased productivity: With split tunneling, users can access the internet and internal resources simultaneously, without having to disconnect from the VPN.
- Reduced bandwidth usage: By allowing users to access the internet directly, split tunneling can reduce the amount of bandwidth used by the VPN tunnel.
Security Implications of Split Tunneling
While split tunneling can offer several benefits, it also poses some security risks. When users access the internet directly, they may be exposing their devices and data to cyber threats. Malware and viruses can infect devices, and data can be intercepted by hackers. Therefore, it is essential to weigh the benefits of split tunneling against the potential security risks and take steps to mitigate them.

What is Split Tunneling in Fortigate and How Does it Work?
Split tunneling in Fortigate is a feature that allows remote users to access the internet directly from their device, bypassing the Fortigate VPN tunnel. This means that when a user is connected to the VPN, they can still access the internet without having to go through the VPN tunnel. This feature is useful for improving the overall user experience, as it allows users to access the internet at their local speeds, rather than being limited by the speed of the VPN connection. By enabling split tunneling, administrators can also reduce the amount of traffic that needs to be processed by the Fortigate device, which can help to improve overall network performance.
Enabling split tunneling in Fortigate involves configuring the VPN settings to allow remote users to access the internet directly. This can be done by creating a new VPN policy that includes the split tunneling feature, or by modifying an existing policy to include this feature. Administrators can also configure the Fortigate device to allow split tunneling for specific users or groups, or to block access to certain websites or applications. By carefully configuring the split tunneling feature, administrators can ensure that remote users have access to the resources they need, while also maintaining the security and integrity of the network.
