iOS Split Tunneling
iOS split tunneling allows you to route specific traffic through the WireGuard tunnel while excluding other traffic. This is useful for scenarios where you want to protect sensitive data while still accessing local resources.
WireGuard supports split tunneling on iOS devices by using the “Allowed Apps” feature. This feature allows you to specify which apps are allowed to use the WireGuard tunnel. All other traffic will be routed through the normal internet connection.
Configuring Split Tunneling
To configure split tunneling on your iOS device, follow these steps:
- Open the WireGuard app and select the tunnel you want to configure.
- Tap on the “Allowed Apps” tab.
- Select the apps that you want to allow to use the WireGuard tunnel.
Once you have configured split tunneling, only the traffic from the allowed apps will be routed through the WireGuard tunnel. All other traffic will be routed through the normal internet connection.

Security Implications
Utilizing WireGuard split tunneling on iOS introduces specific security considerations that must be addressed. Understanding the potential risks and implementing appropriate mitigation strategies is crucial for maintaining a secure network environment.
One primary concern is the potential for data leakage. By selectively routing specific traffic through the VPN tunnel while allowing other traffic to bypass it, split tunneling creates a situation where sensitive data may inadvertently be transmitted over the unsecured public network.
This risk is particularly relevant for devices that are used both for personal and professional purposes, as it increases the possibility of sensitive work-related data being exposed.
Mitigation Strategies
- Implement strict access controls: Limit access to the VPN tunnel to only those applications and services that require it. This reduces the risk of data leakage by preventing unauthorized apps from accessing sensitive data over the public network.
- Use strong encryption: Ensure that the VPN tunnel is configured to use strong encryption protocols, such as AES-256 or ChaCha20, to protect data in transit from unauthorized access.
- Regularly update the VPN software: Keep the WireGuard client and iOS software up to date to patch any security vulnerabilities that may be discovered over time.
- Monitor VPN logs: Regularly review VPN logs to identify any suspicious activity or unauthorized access attempts. This allows for prompt detection and response to potential security breaches.
Use Cases
WireGuard split tunneling on iOS offers a wide range of use cases, providing users with enhanced privacy, security, and productivity.Split tunneling allows users to selectively route specific traffic through the VPN tunnel while allowing other traffic to bypass it. This can be particularly useful in situations where users need to access both secure and non-secure networks simultaneously.
Enhanced Privacy
Split tunneling can enhance privacy by limiting the exposure of sensitive data to the VPN provider. By routing only specific traffic through the VPN tunnel, users can protect their browsing history, personal information, and financial transactions from being intercepted by third parties.
Improved Security
